Thanks, Tina, and good afternoon, everyone. 2020 was a remarkable year for Lam Research. Our global teams rose to meet the unprecedented challenges of the COVID-nineteen pandemic and delivered the best year in our history. Total revenue of $11,900,000,000 and earnings per share of $20.45 were both record highs for the company, driven by served available market, market share and customer support business growth. Through the year, we also launched new products And announced breakthrough technology solutions that we believe lay the foundation for our continued success.
Before going into details, I I want to express my sincere thanks to our teams for their incredible execution in an extraordinarily difficult environment And to our customers and suppliers for their partnership and support as we all adapted to the unforeseen events of 2020. We entered the new year with hope that the world will soon emerge from the COVID-nineteen health crisis and move towards a global recovery. From our view, WFE spending in 2020 ended in the high $50,000,000,000 range. This is about what we estimated at our Investor Day in March, Just before the extent of COVID-nineteen's impact was known, we saw spending growth across all segments of the market, Led by a recovery in NAND, continued expansion in foundrylogic and a slight pickup in DRAM. China domestic spending for the year was in the $10,000,000,000 plus range.
As we look to 2021, We see strong momentum across all parts of our business. Our early view is for substantial WFE growth to the high $60,000,000,000 to $70,000,000,000 range, supported by the ongoing migration to higher layer counts in NAND, A strong spending environment in DRAM and increased investment in foundry logic as indicated by recent customer commentary. Currently, we are seeing spending bias somewhat towards the first half of twenty twenty one. While today's Absolute levels of WFE are significantly higher than a few years ago. We believe the rapid digitization of the global economy, combined with rising capital intensity due to greater process complexity, supports robust multiyear WFE spending.
In fact, this is a common theme that underpins our outlook for the next several years. It is that sustainable growth Throughout the semiconductor value chains will be driven by the proliferation of artificial intelligence, high performance computing, IoT, 5 gs and the incredible societal advances and user experiences these technologies enable. We expect strong demand from a diverse set of end use markets to positively impact semiconductor And semiconductor equipment growth in 2021 and beyond. Take, for example, the $200,000,000,000 global online gaming market. Nearly 3,000,000,000 people worldwide actively play video games across a variety of platforms, generating over the last 5 years More than a 50% CAGR in data growth as users embrace realistic experiences enabled by more powerful processors, faster memory and If you just look at a sub segment of the broader gaming market, namely gaming consoles, The number of these units shipped annually is much smaller than the number of smartphones sold.
However, when you consider that a GPU for a gaming console Is approximately 4 times the size of a smartphone application processor, this is an important driver of incremental WFE. From a memory and storage perspective, newer consoles utilize approximately twice the DRAM bits and employ SSD based storage versus HDD in prior generations. Add rising capital intensity trends on top of this semiconductor content growth And the impact on WFE increases further. We estimate that a 5% upside in the game console market has the potential to drive about $500,000,000 of incremental WFE. And this is just one end use market example.
If we similarly look at the impact of the 5 gs phone market, we see that 5% incremental demand in 5 gs units has the potential to drive close to $1,000,000,000 in incremental WFE. It is demand drivers such as these that have strengthened our conviction around the sustainability of WFE spending over a multiyear period. It is against this positive backdrop That Lam remains focused on executing to our long term objectives for sand expansion, Good share gains and installed base business growth we described at our Investor Day last March. In NAND, we continue to extend our strong leadership position. We estimate that our tools have now cumulatively processed Approximately 37,000,000 more wafers than our nearest competition through the 3 most critical three d NAND applications.
Since we first provided this metric at our Investor Day less than 1 year ago, we have widened the wafers process experience gap by more than 40%. The accelerated learning that comes from our installed base of 3 d NAND systems puts Lam in the best position to deliver the solutions needed to meet our customers' next generation manufacturing challenges. It also allows us to gain early insight into new opportunities being created by technology inflections. For example, In 2020, we announced our new Stryker SE atomic layer deposition system, which employs a unique iStill capability For high aspect ratio dielectric gap fill. This tool addresses a new technology need for 3 d NAND devices Scaling to 128 layers or more.
And production ramp of Stryker FE is underway at multiple customers. 2020 also saw the launch of Sensei, our next generation etch platform. And today, we announced our new Vantex High aspect ratio dielectric etch module on Sensai. Vantex features advanced RF technology And new uniformity enhancements to enable next generation device roadmaps. Zantex and Sensi together collect more data per wafer than ever before, enabling advanced equipment intelligence and to deliver new levels of productivity and process control.
The timing of our Vantex launch intercepts DRAM and NAND roadmaps facing increasingly complex node to node scaling challenges. As a result, Vantex is already in qualification with both DRAM and NAND customers and repeat orders have been received to ramp this system Into high volume production in 2021. For Hungry Logic, we continue to target new technology inflections to expand our opportunity and position. Our TiO GX conductor etch system has been engineered with an advanced RF pulsing capability to meet the unique requirements of extremely narrow high aspect ratio features. It also provides extendibility to future devices featuring nanowire or nanosheet architectures.
Leading edge foundrylogic customers are increasingly adopting Kiyo GX for their Critical front end of line applications at 5 nanometer and beyond, where the need for atomic level precision etch becomes more acute. Moreover, as devices scale, parasitic RC degrades transistor performance. As a result, we are seeing increasing Customer pull for Lam's etch and deposition solutions designed to reduce RC effects, including atomic layer etch for self aligned contacts, New functional films and optimized metal solutions, which reduce via end line resistance by simplifying middle of line and back end of line process flows. In DRAM, we are seeing incremental share and SAM growth also coming from growing complexity of node transitions. We assess that we have greater than 50% etch market share in DRAM and due to the importance of high quality hard masks In mask open etches with EUV, we expect additional patterning share gains in etch and deposition as EUV passes increase Adoption of EUV in foundrylogic and DRAM is also creating a significant SAM expansion opportunity for Lam's dry photoresist solution.
Using this new technology, we believe we can accelerate our growth in both foundrylogic and DRAM By disrupting the existing wet photoresist equipment market, our solution is gaining significant traction with leading customers as they look to improve the cost metrics of EUV patterning. Changes of this magnitude do take time to realize, So with tools now being installed and wafers being run for top DRAM and foundry logic customers, we are pleased with our progress readying this innovative technology for production. And finally, 2020 was another outstanding year for our customer support business group. Our installed base has now reached nearly 66,000 chambers and CSPG revenue growth exceeded chamber growth by a factor of more than 2x for the 2020 calendar year. We generated record revenues for all sub segments within CSBG.
Growth in our Reliant business was driven by automotive, 5 gs and consumer electronics, And we expect these areas to continue to outpace overall market growth in coming years. Meanwhile, We delivered on the expectations we set on our last earnings call for calendar year growth of 25% in productivity focused services And 6x growth in remote support engagements. We are excited about the trajectory and broad strength of this business And especially its proven ability to deliver world class support of complex technologies in high volume manufacturing. To wrap up, Landmark did its 40th anniversary in 2020 with record financial performance,
A
strong slate of innovative new products and services and solid execution on our strategy to expand leadership across markets. As our March quarter guidance suggests, we are optimistic about the opportunities that lie ahead for Lam and believe we are in an excellent position to win. Thanks again. And now here's Doug.
Excellent. Thank you, Tim. Good afternoon And thank you all for joining us today on what I know is a very busy earnings time. I hope you and your families have been safe and healthy since we last spoke with you. I'm really quite pleased to be reporting these outstanding results.
We came in at the high end or exceeded the range for all guided metrics in the December quarter. Despite the challenges we faced during 2020 related to the global pandemic, Lam delivered record financial performance in revenue, operating income dollars and earnings per share. Our December quarter revenue came in at $3,460,000,000 at the high end of our guidance range and represented an increase of 9% from the September quarter. The strength in our performance was driven by investments in all device segments As our customers ramp to meet the demands from a diverse set of end markets such as data centers, smartphones, PCs, gaming consoles, IoT and Automotive. Overall, our revenue increase was not only driven by the labor path equipment needs of the industry, But also by the continuous growth of our installed base.
We continue to add value to our customers by delivering spare parts, equipment upgrades, Refurbished Tools and Advanced Service Offerings. Looking at the details of our systems revenue, The memory segment was strong in the December quarter coming in at 68% of systems revenue. This strength was driven by the NAND Segment, which represented 51% of our systems revenue versus 39% in the prior quarter. December was a record revenue level of NAND quarterly revenue dollars for the company. We have clear leadership positions in the NAND segment With customers investing in equipment for 64, 96 and 128 layer devices.
DRAM investments contributed 17% of our systems revenue. DRAM spending was spread over the 1Y, 1Z and One Alpha notes. The revenue percentage was down slightly from the 19% in the September quarter. We expect continuing healthy investments in the combined memory market as we see prudent inventory and profitability management. On the Foundry segment side, spending remains robust.
We concluded 2020 with a record level of revenue dollars in this segment. Majority of the investments in the December quarter were concentrated at the leading edge 7 5 nanometer nodes. Foundry represented 26% of our systems revenue for the quarter versus 36% in the September quarter. Rounding out the systems revenue picture, logic and other contributed the remaining 6% of systems revenue in December quarter, which was flat with the prior quarter level. From a regional revenue perspective, we continue to see solid levels of investment in the China region, Coming in at 35% of total revenues.
Different than the last several quarters, the majority of the China spending this quarter came from our global multinational customers investing in their China located fabs. As Jim noted, we achieved another record quarter of revenue for our customer support business group coming in at $1,100,000,000 which is an increase of 12% from the September quarter and over 35% higher than the same quarter in 2019. The growth we've seen in each of the sub segments of this business is a testament to the value we're providing to our customers for technology and productivity enhancements. We remain very comfortable with our commitment to deliver greater than 40% cumulative CSBG revenue growth between 2019 2023 As we outlined at our Investor Day in March of last year. The December quarter gross margin was 46.6%, Generally in line with our expectations.
As I've noted in the past, gross margin could fluctuate quarter to quarter due to overall business levels, Along with customer and product mix. In the quarter, our factory utilization levels improved with the increased business volume. I would mention, we do have continued headwinds to gross margin related to elevated costs for airfreight that will impact us until freight planes get back to more normalized levels. Operating expenses for December came in at $563,000,000 which is an increase from the prior quarter, largely as a result of increased incentive compensation expense that was tied to our higher profitability levels. During calendar year 2020, we spent over $1,300,000,000 in research and development, which represents approximately 2 thirds of our operating expenses.
The R and D focus is a fundamental part of offering differentiated products and capabilities like Sensai and Vantex, Enhanced ALD and Drive Resist that deliver on our long term growth objectives. We had over $1,000,000,000 in operating income in the December quarter for the first time in company history with operating margin at the high end of the guidance range coming in at 30.3 This was due to our strong revenue and gross margin. Non GAAP tax rate for the quarter was 11.5%. As we've discussed in the past, we will have fluctuations within tax rate from quarter to quarter and you should continue to expect the ongoing tax Great to be in the low teens level for the 2021 calendar year. I would mention, we are monitoring potential tax Changes that may arise from the new administration in the United States.
Other income and expense was approximately 53 $1,000,000 in expense, fairly flat with the prior quarter. I would like to remind you that beginning in the March 2020 quarter, the benefits and costs Our employee deferred compensation plan are no longer mismatched in our non GAAP results. They are mismatched in the GAAP results. This mismatch was $24,000,000 in the December quarter. You can see this in the GAAP reconciliation table of our earnings release.
The fluctuations were higher this quarter due to the volatility in the market. Let me now turn to our capital return activity. For the December quarter, we paid $188,000,000 in dividends and allocated $703,000,000 towards share repurchase. During the quarter, our Board Approved an additional $5,000,000,000 share repurchase authorization. For calendar year 2020, we repurchased 3,800,000 shares, Deploying $1,400,000,000 at an average repurchase price of approximately $3.60 per share.
We also paid out dividends totaling approximately $686,000,000 during the year. In total, our capital return activities represented close to 100% of our free cash flow. I'd also mention that since we increased the level of our capital return back in 2017, we've paid out $2,100,000,000 in dividends And deployed $9,300,000,000 towards buybacks, repurchasing 47,300,000 shares at an average price of $198 per share. Diluted earnings per share came in at $6.03 A little above the guidance range and more importantly at an all time high for the company. Our diluted share balance was down slightly from the September quarter Coming in at 146,000,000 shares, pretty much as we forecast.
The share count includes the dilutive impact of approximately 800,000 shares from the 2,041 convertible notes. Let's now look at the balance sheet. Cash and short term investments, including Trusted cash decreased to $6,300,000,000 from $6,900,000,000 in the prior quarter, largely due to the capital return activities that I discussed previously. Day sales outstanding increased to 76 days in the December quarter from 66 days in September. The increase is largely due to revenue linearity and the timing of collections that fell in the March fiscal quarter.
I'd just mention that we collected $136,000,000 on the 1st day of the March 2021 quarter And over $570,000,000 during the 1st week. Inventory turns were slightly up from the prior quarter level coming in at 3.2x. Cash flows from operations came in at $345,000,000 which is somewhat depressed as a result of the growth in accounts receivable And inventory. We've grown inventory to support the higher expected large business volumes and to mitigate supply chain risks from any potential disruption from the COVID-nineteen environment. Non cash expenses included approximately $52,000,000 Equity compensation, dollars 59,000,000 for depreciation and $17,000,000 for amortization.
Capital expenditures for the December quarter increased from September to a total of $92,000,000 We are investing to support the expanding operations at our new Malaysia factory, our manufacturing Facility in Ohio that's focused on critical spare parts and the recently announced Korea Technology Center. We expect to see somewhat higher levels of capital expenditures in 2021 as we support these critical initiatives. And the headcount for the December quarter was approximately 12,200 regular full time employees. Resources have been added to support the increased business volume in our factories, to service our customers in the field And to further enhance our R and D capabilities. Now looking ahead, I'd like to provide our non GAAP guidance for the March 2021 quarter.
We're expecting revenue of $3,700,000,000 plus or minus $200,000,000 Gross margin of 46%, plus or minus 1 percentage point, operating margins of 30.5%, plus or minus One percentage point. And finally, earnings per share of $6.55 plus or minus $0.40 Based on a share count of approximately 145,000,000 shares. Tim has already given you our outlook for 2021 WFE. I'd just reiterate, we do think it will be a somewhat first half weighted spend, although things could change as the year unfolds. You should take that into account as you build your models for the year.
So in summary, we just concluded the best financial year in Lam Research's history. Additionally, we provided guidance for March that represents another record level of financial performance. The company is executing well in a challenging environment. We're delivering on our near term objectives while laying the framework For continued long term execution. This is a testament to Lam's leadership team and our dedicated employees.
Operator, that concludes my prepared remarks. Tim and I would now like to open up the call for questions.
Thank
And we'll take our first question today from John Pitzer with Credit Suisse.
Good afternoon, Tim. Doug, thanks for letting me ask the questions and congratulations on the great results.
Tim, I just want
to go back to your WFE target guide for this year of high 60s to 70. If you harken back to the Analyst Day almost a year ago, your 3 to 4 year target out was sort of a range of And so I'm curious, how should we think about how quickly we've gotten here? Do we worry about overheating. And in a similar vein, as you think about this year being perhaps a little bit more first half weighted, is that really a commentary on Normal seasonality, you want to add capacity in the first half for demand in the second half? Or as you look at the bottoms up, are you worried about any areas that are kind of Perhaps cyclically heating up a little bit too much.
A lot of questions in there, John.
Yes, but maybe there was
a comment in my script even that was that said, in many cases, the outlook we gave at Investor Day, Yes, that was formulated before we really knew about COVID-nineteen, before we saw all of these tremendous work from home drivers, A lot of things have just really kind of changed maybe the way semiconductors have and the role semiconductors have played kind of in the world In the last 12 months. And so we give our best view when we give it. And at that time, we thought a range of $60,000,000,000 to $70,000,000,000 seemed pretty reasonable Given what we thought about demand, clearly, some segments of the market have been growing a lot faster, as we just mentioned, from those demand trends. When we look at it, There is an urgency to get tooling to meet demand. And that's not just that's not our customers, that's also us as we look.
Doug talked about investment in our Ohio facility to build critical spare parts as factories are running at very high levels of utilization. So we're investing. Our customers I think the outlook is difficult to say. We're selling you right now. It looks like it's 1st half somewhat 1st half weighted.
But I also talked about long term demand drivers that we think fundamentally continue to Become growth drivers for this industry in the long term. And we've just seen growth in I'll give you a couple of examples, 5 gs, Gaming consoles, everybody's read about the shortages in automotive image sensors. There's just Such a role that semiconductors play today. I don't think there's any segment we would point to that we feel is Overheating relative to the long term trends we've talked about. Just one example, because I know we'll get the question at some point on NAND.
We talked about the recovery in NAND. But if you look at the spending on NAND over the last 3 years and you average that out, it's actually very close To the average annual spending that we've outlined for a couple of years at the Flash Memory Summit, which says that you need roughly $70,000,000,000 Over a 5 year period to hit the high-30s demand bit growth rate. And so we feel reasonably comfortable with the demand Profiles across all the segments right now. And there'll be changes quarter to quarter and such. But long term, we think they're in line with the demand we're seeing.
Very helpful. Thank you. Thanks, John.
Next, we'll hear from Krish Sankar with Cowen and Company.
Yes. Hi. Thanks for taking my question. Just to follow-up on the WFE commentary, is there a way to quantify it How much is it pent up versus back half? And if there is any upside to back half, anything is going to come from memory, Gillette, China, anything?
And then I had a quick point on. Yes. It's well, we haven't quantified I don't think we're going to do so right now. Doug is shaking his head no. I'm going to right now.
But I think that to your point and Doug kind of mentioned it's like this is our view now. You can always feel the demand and the urgency for the next couple of quarters much stronger than the quarters further out. So I think your question is a good one, which is Where might we see changes later in the year? I think you have to look at some of the demand drivers. And again, there's a broadening of demand across It's not just driven by leading edge.
In fact, we were looking at the amount of foundry spending, for instance, that's coming from 28 nanometer and above. It's at very high levels these days. You see that in strength that gets reported into our CSPG business, the Reliant business. I think you can continue to see strength there. It's how semiconductor is being incorporated into everything.
The content in cars and such is just Increasing at quite a rapid rate and those tend to drive kind of that off leading edge business at a very rapid pace. Where that gets manufactured? I mean, there is a fair bit of investment in China, for instance, that is at those trailing edge nodes. And I think that's why we have seen strength in China and why we actually believe that China, especially at those trailing edge nodes, continues to be An area of strength is they satisfy a lot of that domestic demand for those kinds of applications like 5 gs and cars And other things. So, I guess you could say there might be added strength in those broader demand drivers that could surprises later in the year.
Got it. That's super helpful, Tim. Just a quick follow-up, in your WSU assumption for this year, what are you modeling for domestic China? You You think there's $10,000,000,000 after? I'm just kind of curious where it's shaping up for this year.
Thank you. I don't think we're ready to give That's an exact number, but what we've said is it's $10,000,000,000 plus this year and we expect growth this year.
I don't know if
Doug wants to add anything. Yes. It's
probably in the same range, Chris, plus minus a little bit, is kind of how we're thinking about
Thanks, Doug. Thanks, Matthew.
Next, we'll hear from Timothy Arcuri with UBS.
Hi. I guess, Doug, I wanted to ask the prior question maybe a little bit differently. You said WFE this year is probably 58.5 sorry, This year or last year, probably about 58.5%. So your share grew about 100 basis points up to like 13.6%. So if I assume that the service business, maybe you could help Tom if this is right, but it seems like service is going to be maybe $12.25 or $12.50 in March.
So if you use that same share number, you get like an $18,500,000,000 $18,500,000,000 worth of WFE in Q1. So that's almost $74,000,000,000 annualized. So I sort of look at the full year number of you're guiding high 60s to 70. So that would sort of imply that the back half of the year has to be at least for the industry has to be down pretty substantially off of where the first half of the year is Or at least after the way Q1 is running. So I'm just kind of wondering if you can comment on that and sort of like double click on that.
And then I had a follow-up. Thanks.
Yes, Tim, I'm not going to unpeel the whole number. So we do and I can't go through all All the numbers as I sit here that you just stood out. I'm sure you're doing the right math or close. As we look into the year, it does look like a first Half weighted year. Things move around, things change.
I think probably NAND is First half weighted, I think Foundry Logic probably a little bit also. And I think Deere Amp probably through the year is fairly steady. Things move around, things change. We always have pretty good visibility at this point into the first half and the second half is far enough away that it can move around. So that's That's why we kind of try to put some ranges.
You guys will do the math, to kind of think it through. I I don't know if I'm helping you here, but that's generally what I'm seeing and how I'm thinking about it.
Okay, cool Doug. Thanks. And then I guess my second question is on NAND. So it looks like CapEx is going to run above EBITDA this year for the industry. I mean, You're going to the industry probably does $19,000,000,000 in NAND.
I don't know if you'd agree with that, dollars 19,000,000,000 WFE this year. So that's pretty substantially above the $14,000,000,000 run rate that you get when you divide your $70,000,000,000 by 5. So I guess when you take those two factors and you look at CapEx Speaking about EBITDA, usually that's not all that sustainable. So I guess, what's the tone of your customers? Do you does that concern you at all?
Just really curious on that. Thanks.
Tim, when you look at this, it will go up, it will go down. Nothing goes up every quarter. It ebbs and it flows. And if you go back to 2019, it was pretty low. If you go through 2020, it went up a little bit.
2021, Flat to up a little bit, maybe, yes, probably. And then it will course correct based on whatever demand looks like. I mean, when we step back on the reason Tim and I both talked about these long term demand drivers, is that's the important thing to think about over the next several years for the industry. It won't go up every quarter. It never does.
You know that better than I do or as well as I do. And timing of fab investment, when things come in, It'll go up, it'll go down. That is what always happens and is what will happen in 2021 most likely.
Yes. And I think if I was just to add, Tim, I mean, it's Yes. The absolute spending in NAND in any given year is somewhat out of our control. But I mean, what we do control is How we continue to expand share of every dollar of WFE spent, and that's why I talked about how we've leveraged the learning we're getting from Being the company that runs the vast majority of the critical applications in NAND, to identify And we've introduced new applications and grow into those so that the next node, our share of WFE goes higher. And I talked about Stryker FE, The ALD tool for Gap Fill, brand new application for us, competes in a space where we didn't compete before.
And As node transitions occur into the future, it means that our share of WFE increases. It's also important to remember that Our share of every dollar WFE spent on node transitions actually is the highest. And that's simply because of the role that debt and debt position play in those transitions. So if you end up in a year, let's say, and I'm not characterizing Any given year in this way, but if you end up the year where you do add lots of wafer starts, people become concerned that that might be Bit of overheating with new capacity, but actually we look at it as adding to what we would consider to be kind of our 3 d annuity, The 3 d NAND annuity, which says installed base is larger, which means that the next transition, Lam will get an even greater share of the spending that is required to move that entire 3 d NAND installed base forward to the next node. So, Doug said, any given year, something happens.
In the long term trend, we think Lam's opportunity continues to grow in 3 d NAND. Totally. Thanks, Tim. Thanks, Tim.
We'll now hear from Bijan Muse with Evercore.
Yes. Hi. Thanks for taking the question. Question for you on CSBG business. Is your commentary on the first half weighted year reflective for that business as well?
And as part of that, if I hold the business just flat at Q4 level, that business would run about 16% in calendar 2021. So How should we think about the growth rate this year? And then I have a quick follow-up.
Yes, C. J, my commentary on first half, second half was very much targeted at WFE, not necessarily installed base. No, the installed base won't necessarily grow every single quarter. We'll grow every single year, like we've been saying. We feel really good about where we're at though.
I mean, it's we're record after record, and Tim shared the chamber count with you. It's Kind of like it's been over the last several years. So the tailwind there is really very good. Yes.
And I guess I'd just add, at our Investor Day, we talked about the goal we And to expand the number of products and services available for the installed base is a way of increasing revenue per chamber. I think you've seen our progress in that area in this past year, and we'd expect that to continue to Increase going forward as we focus on equipment intelligence and remote services and a lot of database productivity enhancers. That's great. And as a quick follow-up, on your last call, you talked about how given the preponderance of manufacturing in Fremont, You couldn't shift to 1 large logic player in China. Curious if you've been able to get a license and as part of that, Are you including the spend there in your 2021 domestic China outlook?
Thank you.
So where we're at right now, CJ, is we're still in the application process for license, haven't heard back. When we look at China, that's plus or minus how we described flat to up. There's a range around it. But at this point, we haven't heard back on the license we have applied and we're waiting. Thanks, Ted.
Yes. Thanks, CJ.
Next, we'll hear from Harlan Sur with JPMorgan.
Good afternoon and congratulations on the solid results and execution. For all of the leading growth leading edge growth trends that you highlighted in your prepared remarks, Tim, is there a corresponding significant attach rate of analog and mixed signal semiconductors to these applications?
Additionally, some of your customers
are moving to 12 inches analog manufacturing. And then we know that there's pretty Significant tightness in foundry capacity for lagging edge 2840 nanometer CMOS. So approximately And obviously, I think you mentioned this is driving some of the strength in your business. Approximately, what percent of your overall business is lagging edge technology nodes? And do you see this Standing as the year unfolds?
Yes. We're I mean, we don't break out exactly what percentage of our business is in that segment, but I did say We do see that area continuing to grow. Again, and it's that's like what we would always consider to be the strongest secular growing part of our market because it's being Driven by almost every aspect of the economy in terms of the types of products that semiconductor is going into that are manufactured at those And so we've seen I don't maybe I think it's something like I could get it wrong, it's 8 or 9 quarters, I We've now had reported record revenues in that trailing edge space. So one, We feel like we know how to compete and address that market, and we think that it's going to be just one that just continues to grow, Maybe not quarter over quarter over quarter, but records every quarter, but certainly year to year to year, it will continue to be an area
And Harlan, I'll just remind you what we said back at the Investor Day in March and still believe that this segment of WFE will outgrow the rest of the market by, I don't know, 2 times, maybe 3 times, although the leading edge stuff has picked up since then, but it's still a very good growth area for us.
Yes. No, thanks for the insights there. And then to kind of follow-up on CJS' question, in calendar year 2020, as you mentioned, services grew 22%. That's not only double your installed base growth CAGR over the past few years, but it's doubled the trend line target of around 10 As it relates to your 2023, 2024 financial model. And if you just look at the continued complexity on these next generation leading edge tools, The strong demand for lagging edge nodes, it appears that the service business is going to continue to grow faster than this 10% growth target that you guys have put out there, Upgrades, advanced services, Reliance, refurbished tools.
So would you broadly agree with that? Or are there some offsets that we To be thinking about that could dampen the year over year services trajectory back to that kind of normalized kind of 10% to 12% level?
Yes. I don't think we're ready to up our long term objective just yet, but I think you're pointing out
Some of
the things that are doing quite well in that part of the business around Advanced Services, and we talked about a 6x Increase in remote support engagements. I think if we look, 1, we put out that model at Investor Day. As I mentioned, As the COVID environment kind of evolved, some of the advanced services, the database services, the pull for the idea of like less People related maintenance using data and remote capabilities clearly caught a lot more traction in the second half of the year. We need to see how much of that sticks As we kind of come out of this environment, but we believe that those things are those capabilities are now kind of demonstrating their value and a lot of that Those will be strong drivers. The other thing that happened in 2020 is there probably were some instances of Spares being ordered a bit ahead of normal trend as everybody, including land you see in some of our inventory numbers, Tried to hedge against disruptions due to COVID-nineteen.
And so you might see some moderation if you're looking for offsets in that So we feel, as Doug said, very comfortable about hitting the objective we put out at the Investor Day, but we're not ready to set a New growth target for that business until we see a little bit more of the trend this year.
Great. Thank you.
Thanks, Charlie.
We'll move on to Vivek Arya with Bank of America.
For the first one, I'm curious, what do you think is the right way to gauge the utilization of your NAND shipments last year? Is there some engagement with those customers on the CSBG side that gives you insight into what that Call based utilization is because I imagine the NAND number, at least to us, was somewhat of an upside surprise, and I just wanted to understand what's driving that?
Well, I guess if I understand the question about you're kind of asking How much the tools that we've shipped are being utilized in our customer's fabs, and that's not something I can really comment on. Obviously, through our engagements with customers, we have good insight into that, But it's not something we can really talk about. If I misunderstood the question maybe
Or maybe if Tim, What do you think is the supply demand balance for NAND right now among your customers?
Well, I think we I think if you consider that we talked about further strength in the NAND market into 2021, I would say that There is a sense that more equipment is needed to bring on additional capabilities in VAND at this point in time, for sure.
Got it. And as a quick follow-up, Doug, I think you alluded to some cost headwinds from airfreight. Some of your semiconductor peers, I think, have managed to kind of pass on increasing costs in other areas, foundries and wafers and substrates and so forth. Do you think this is the kind of cost you could pass on? I'm trying to think how do you go from your operating margins right now To the 32% to 34% kind of range you had outlined at your Analyst Day at similar level of annualized sales?
Yes, Vivek. I mean, we're always trying to get the best pricing that we can get. It's hard at times though to kind of pass stuff like this through. We're doing our best. It is a bit of a headwind.
So I guess we're not able to push it through at this point. I do think this Part of things will mitigate at some point as the world gets back to normal and freight lanes get back to normal. Things are just Constrained right now, we fly things in and out of our factory a lot, oftentimes or at least we used to on the belly of a commercial aircraft At times, they're just not flying at the volume that they used to be. I do think that gets back at some point once we get COVID under control in the world.
Any way to quantify the headwind, Doug? Is it like 100 basis points to gross margin, 50 basis points? Any color on the
Yes, Vivek, I haven't given a hard number, but I would tell you it's noticeable. It's meaningful. It's a meaningful head vendor. I wouldn't be talking about it. And we're doing our best to manage it.
And I do believe it will get better over time, but I haven't quantified it.
Understood. Thank you.
Thanks, David.
Next, we'll hear from Joe Moore with Morgan Stanley.
Great. Thank you. You talked about the drivers of the higher WFE in calendar 21. You talked about migration to higher layer accounts in NAND As well as DRAM and Foundry. I guess in the NAND side, does that mean you think NAND spending is higher for the year or are you not going to go that far?
And then for DRAM, it seems like the economics are improving. Do you think that's were people spending sort of independent of that, just thinking they needed to get a Technology migration or have you seen sort of stronger spending because the market has been stabilizing and improving?
Yes, Joe, I'll start and then I'll let Tim add on as well. As we look into 2021 right now, pretty much we see every segment of our business up, Right. It's up in Foundry Logic. It's up in NAND. It's up in DRAM.
To different degrees and like I Kind of alluded to earlier, things can change, but that's our outlook right now. And again, we see these longer term demand drivers as a large part of what's going on. I don't know, Tim, if you want to add anything.
No, I think you pretty much got it. I mean, I think if you're you started the question about NAND. I mean, again, It's again this layered transition is a way for customers to reduce their cost and but those transitions are complex from a net So creating a lot of demand for our tools to help enable those transitions.
Yes. And to the extent that A lot of the NAND spending is on layer count migration rather than adding incremental wafers. I mean, does that wouldn't Lam normally outgrow the WFE In that kind of environment, assuming there isn't like a lot of capacity being added in NAND?
Yes. Joe, in the conversion as Tim alluded to earlier, when you're just doing the layer count conversion, that's a sweet spot For us in terms of the percent of spend, so the answer is yes, with the caveat that everybody's installed base is a little bit different. There's always A handful of new wafers coming in. You got to kind of peel the onion back to the next layer and look at what's going on in any one period. But I would agree with your comment that in a layer count Conversion, that's a good spot for us.
Great. Thank you very much.
Thanks, Joe.
Toshiya Hari with Goldman Sachs has our next question.
Hi, guys. Thanks for taking the question and congrats on the strong results. I had 2 as well. My first one is somewhat related to Joe's question. Wanted to get your thoughts on your ability to outperform WFE in 20 Tim, given sort of the application wins that you have in the bag and given sort of the device type mix that you guys are assuming internally, would it be fair to assume kind of a similar magnitude of outperformance in your systems business in 2021 Vis a vis 2020 or do you think 2020 was a little bit unique given how strong NAND was in the year?
Tim, as I'll answer, that's a lot of information you're asking for. As we look, I mean, Doug just mentioned, I mean, clearly, we see strength across All parts of the business. I mean NAND expansion is clearly good for us. As I mentioned in my comment, More than 50% share in DRAM etch. We're expanding our deposition, so DRAM is good.
Foundry logic is an area where, Obviously, from an exposure perspective, land has it's been less in the past, but we've talked about our improvements there. And so I think even there as the nodes move forward, some of these new products we're talking about, whether it's dry resist, That might not be a 'twenty one story, maybe but more of a 'twenty two and beyond story. But we're working hard to increase our SAN as percent of WFE. And I guess what I'd just say is in terms of outperformance, you got to go back to what we said at Investor Day, which is the way our path to outperformance is To expand our SAM and coming from where we are in the high 30s, you said we're going to get to 40% SAM as a percent of WFE. That's increasing our opportunity.
And then we do think with new products like the Vantex on Sensai and other products that are kind of in the pipeline to Coming later this year, those will be market share drivers for us. And so combination SAM expansion and market share gains Hopefully, it's lead to continued outperformance of the market.
Yes, that's helpful. And then, Tim, as my follow-up, you just mentioned Ventex, Pretty fascinating technology. Wondering if you could kind of give us some color Areas or points of differentiation vis a vis your nearest competitor in Asia. And if you can remind us what your market share aspirations are in Dielectric Hatch over the next Couple of years, that would be super helpful, just given how relatively speaking, you've been stronger in Conductor X. So I think the opportunity set is bigger in dielectric.
Thank you.
Yes. Okay, great. Well, just a couple of things. I mean, one, the VanTek story is really like 2 parts. One is, It is the first module on the new Sensai platform.
So again, when you're thinking about Sensai, you're thinking about Tremendous amounts of data collection and using that not only to improve the productivity of
the platform and the
maintenance and such, but also Process control, and as you look at now in that dielectric high aspect ratio etch, which is where Vantex is targeted, Those edges are becoming incredibly difficult, both in NAND and DRAM where that product is really targeted. We've leveraged the learning from all of those, those wafers I talked about. We've been running relative in 3 d MAND to really understand what it takes to build the world class high aspect ratio etcher and that's what we think we've delivered to the market. We do really well in dielectric etch, quite honestly, in both DRAM and NAND already. But We're not going to we haven't quantified, I believe, our dielectric etch ambition, but clearly it's higher in years to come.
And we think FAMPTEC's on since
I is The platform to do that.
Got it. Thank you so much.
Thanks, Toshiya.
We'll now hear from Blayne Curtis with Barclays.
Hey guys, thanks for taking my question. I wanted to go back to the Last quarter, you talked about obviously, you didn't want to guide WFP, but
you gave
us guideposts and obviously DRAM was the strongest. Now fast forward, We've all seen big foundry CapEx numbers, but your NAND came in strong as well.
Can you talk us through
the last 3 months, what kind of improved for you? I know you don't want to spout in perfectly for the year, but just trying to still get a better feel as to what you're expecting between those two segments.
I don't know, Blayne. Obviously, one large foundry customer upsized their CapEx. I think everybody understands what happened there. I don't think Many of us saw the totality of that coming. So clearly, that was a bit of the upside.
Maybe that would be the only thing I would specifically point to.
Got
you. And then just back on gross margin, obviously, you have the higher freight costs, you're guiding it down a bit, revenue up. Can you just kind of walk us through the March guide and then just opportunities for leverage either gross margin or even on OpEx as you look through the rest of the year?
Yes, Blayne, thanks for the question. I think you know and everybody knows, this isn't really a Huge fixed cost business. So when revenue goes up, it matters, but it's not what matters as much as in like our customers business. Product mix matters, customer mix matters, customer concentration moves gross margin around. That's happening probably a little bit in the March quarter, a little bit of a headwind.
If I think about the longer term, Getting to that financial model that we put out for 2023, 2 things I would point you to on the gross margin and operating income for that matter. One is this freight headwind that we're dealing with. 2nd, I referred to ramping the factory in Malaysia. That's going to be a somewhat more efficient, little bit bigger factory, little bit more cost efficient factory. So there's some upside that We're going to see a gross margin there, and that's really from where we are today to where we're trying to get to or where we're going to get to, what gets you there.
Got you. Thank you.
Thanks, Glenn.
Our next question will come from Atif Malik with Citi.
Thanks for taking my questions. Tim, you guys have seen strong growth in 3 d devices, particularly in NAND area And they're announcing the new technology for high asset ratio. My question is in the logic side as the logic devices are now moving in 3 dimensions, Horizontal nanosheet, the 3 nanometer Corian foundry this year. How does that impact the depletion etch opportunity? And should we be looking at that as A major inflection.
I would hope you would be. We've been talking about really At some point along the roadmaps, every device ultimately is inflecting to 3 d simply because that's how you get continued scaling. And so I talked about our Keyo GX tool. You start seeing new types of technologies come in, in the etch and also deposition space. I mentioned that tool with its atomic layer etch capabilities, those tools are well suited to the types of 3 d devices you're going to see in nanosheet or And a wire architectures.
There will also be other tools, which we haven't really talked about so publicly, but they are in the hands of our customers Around selective etch that will become much more prevalent within 3 d logic foundry devices. And then a whole slew of new deposition films that also help. I mentioned some of the RC and such. So Yes, I think it's an area where we can continue to expand our SAM by catching kind of those 3 d inflections in logic and foundry. Our R and D that Doug talked about is really targeted a lot towards growing our opportunity in that space.
Great. And Doug, you have heard about supply constraints in chips and printed circuit boards. Is the availability of chips impacting your capability to build the percent for your customers?
Yes. In any supply chain as complex as ours is with as many suppliers as we have, there's always something that You're working your way through. And certainly, there's a handful of those things today given volume is inflecting up, but we're managing through it pretty well.
Thank you. Yes. Thank you.
Operator, we have time for one more question, please.
Certainly, our final question will come from Joe Quatrochi with Wells Fargo.
Yes. Thanks for taking the question. On your expectations for domestic China being flat to up, how are you thinking about the efficiency of spending this year as the customers Continue to ramp up their technology curves?
In China specifically, Joe, is that your question?
Yes. For your domestic China customers, I think in the past you talked about there's some level of inefficient spend just given that they're still kind of learning.
Yes. Our domestic China customer base is very broad. It's much broader, I think, perhaps than all of you realize. And you've got people at all kinds of different points along ramping technologies. Some are been doing it for a really long time.
Some are brand new to certain When a customer is new to a technology, it takes a little while to get to an efficient ramp point. So it's a broad set of Customers that are at different points, I think is what I would describe. Again, depending on how long they've been doing, what they're doing.
Okay, fair enough. And then quickly on just the DSGB side, how are you thinking about the improvement of Memory fab productivity last year contributing to the growth. And then how do we think about that this year? Because I assume that the spare parts Business would be more of a modest contributor to growth for that business this year.
Let me think about that question and I don't know, Tim, if you have anything you want to add. I mean consumption of spares will ebb and flow across Every one of our end markets with utilization, the utilization size, spare part consumption is somewhat higher. It's just the nature of how It's a consumable part, obviously. So it needs to go along with volume. I don't know if I'm Answering your question, but that's true in the memory fab, just true in foundry and logic as well.
As Tim suggested, maybe there was a little bit of buy ahead in spares, maybe a little bit, but I don't think that was huge. I don't know
if you No. And I don't think that It was something that would be specific to memory, but in general, a couple of comments we've made about spare parts maybe just to comment is, We have always focused on the critical applications because critical applications, you have to keep those chambers in Very pristine condition in order to be able to deliver the EnWave result the customer needs. They tend to be bigger drivers of spare parts. And so I think as each of these technology nodes gets more complex, spare parts and the capability of those spares continues to grow. That's good for our business.
But the flip side of that, of course, is that's customers' cost. And so that's why we are continuously looking for things like the new Sensai platform to Help our customer reduce maintenance cost and running cost of the systems. I mentioned Sensei and Bantex, The first adopters and the first ones to ramp that to production are going to be in the memory space and that's simply because it delivers technology Hash high productivity and that's really the key. How do you find that balance of getting the results on the wafer without consuming too many spare parts and without Consuming too much of the tool equipment time. I think Lam has become very good at that.
And I think that again, we point to The volume of learning we have in high volume production, cross band and DRAM cost sensitive applications, I think we may be the best at that. Thank you.
Thank you, Jeff.
That will conclude today's question and answer session. I will now turn Call over to Ms. Correa for any additional closing remarks.
We just wanted to thank everyone for joining today, and we will talk to you all again soon. Thank you.
That will conclude today's conference. Thank you for your participation. You may now disconnect.
