It's time for us to start Tokyo Electron Financial announcement for the second quarter of fiscal year ending March 2026. Thank you very much for joining us today despite your busy schedule. I am Yatsuda of IR Department, serving as the moderator for today's session. Let me introduce today's attendees. Toshiki Kawai, Representative Director, President and CEO. I am Kawai. Thank you very much. Hiroshi Kawamoto, Senior Vice President, General Manager, Division Officer of Finance Department. I am Kawamoto. Thank you very much for joining us today. Before starting the presentations, let me explain the flow of today's session. First of all, Kawamoto and Kawai will make presentations. After that. Until 6:00 P.M. Japan time, we will have a question-and-answer session where we entertain questions from the audience. This meeting uses two channels of Webex for the simultaneous interpretation between Japanese and English.
As we explained in our email, you are kindly requested to use apps on PCs and mobile terminals if you wish to ask questions, but if you're not going to ask questions, you can use telephones. Since this conference is intended for institutional investors and analysts, we would appreciate your understanding that we receive questions only from institutional investors and analysts as usual. We will post the audio contents of this conference in Japanese and English on our website within a couple of days. It would be appreciated if you could also visit our website. First of all, Mr. Kawamoto will present the consolidated financial summary. Once again, good afternoon. I am Kawamoto, Finance Division. I'd like to present the consolidated financial summary of the second quarter of the fiscal year ending March 2026. This slide shows the quarterly financial summary.
I will mainly refer to the figures in the blue box. In the second quarter, we generated net sales of JPY 630.0 billion, which is in line with our guidance, a 14.6% increase quarter over quarter. Gross profit was JPY 284.8 billion, a 12.12% increase from the previous quarter. Gross profit margin was 45.2%, a 1.0 percentage point drop quarter over quarter due to the increased ratio of fixed costs. Operating income was JPY 158.4 billion, a 9.5% increase from the previous quarter. Operating profit margin was 25.1%. Declined by 1.2 percentage points quarter over quarter, mainly due to the impact of increased development expenses. Income taxes increased by 6.0% to JPY 161.0 billion. Net income attributable to owners or parents was JPY 123.8 billion, a 5.1% increase quarter over quarter.
Capital expenditures in the second quarter were JPY 991.2 billion, consisting mainly of the payment made at the start of construction of the production building at Tokyo Electron Miyagi and development building of Tokyo Electron Kyushu. This is a graphic representation of the financial summary shown on the previous page on the chronological basis for your reference. This shows the financial summary on the semi-annual basis. The figures in the blue box are financial results in the first half of this fiscal year. The far right column shows the financial estimate for the first half of this fiscal year we announced on July 31st. As you can see, our results, in most cases, exceeded our guidance. This slide shows net sales by region. As for the composition in the second quarter, the proportion of Korea rose by 5 percentage points quarter over quarter to 21.1%.
The proportion of sales in China was 40.3%. In the second quarter, reflecting the trend of pulling forward from the second half of this fiscal year. This shows SBE new equipment sales by application. In the second quarter, from the bottom of this chart, sales to non-memory customers accounted for 59%. Non-volatile memory accounted for 14%, and DRAM accounted for 27%. In the first half of this fiscal year, the composition of SBE new equipment sales by application was mostly in line with our estimates. This shows the field solution sales. In the second quarter, field solution sales were JPY 160.3 billion, thanks to the high utilization rate of the customers' fabs in the second quarter. Sales of services were strong, and modifications increased as well. As a result, field solution sales grew by JPY 19.1 billion quarter over quarter. This slide shows the balance sheet.
The total assets were JPY 2,667,000,000,000 . Cash and cash equivalents were JPY 455.2 billion, increasing by JPY 87.7 billion from the previous quarter. Notes and accounts receivable were JPY 411.4 billion, increasing by JPY 18.1 billion quarter over quarter. Inventories were JPY 720.4 billion, declining by JPY 36.6 billion from the previous quarter, partly because of a drop in inventory at the factories. Tangible assets were JPY 561.2 billion, increasing by JPY 80.9 billion from the previous quarter, primarily due to the capital expenditures that I mentioned earlier. For the liabilities and net assets shown on the right-hand side, liabilities were JPY 662.3 billion, increasing by JPY 25.8 billion from the previous quarter. Net assets were JPY 2 trillion 4.6 billion, rising by JPY 131.8 billion quarter over quarter. The equity ratio was 74.4%, just for your information. This slide shows the cash flow.
The cash inflow from operating activities in the second quarter was JPY 175.8 billion. The cash outflow from investing activities was JPY 86.7 billion, mainly due to the acquisition of fixed assets. Cash outflow from financing activities was JPY 1 billion. Free cash flow was plus JPY 89.1 billion. This concludes my presentation. Thank you very much. Now, Kawai-san will make a presentation regarding business environment and financial estimates. Kawai-san, go ahead, please. This is Kawai. Once again, thank you very much for joining us today. I will present business environment and financial estimates. Let me start with the business environment. CY 2025 WFE market is expected to be $115 billion in size as projected in July. Investment in the mature nodes is soft in general, while investment in NAND is now picking up after being soft over the past few years.
In particular, advanced logic and DRAM for AI applications are driving investment. The era of AI shows here. The strong AI server demand and technology innovation of semiconductors, essential for AI servers, will act as powerful drivers to continually lead a dramatic growth of investment for leading-edge semiconductors. For DRAM, investment not only for HBM but also for commodity DRAM is growing sharply. Double-digit growth is expected to continue next year and beyond. For NAND, along with the growing demand of SSD for data centers, namely enterprise SSD, utilization rate is improving at our customers' fabs. For logic, along with device scaling to 2 nanometer and 1.4 nanometer, further investment growth is expected in the future. The need for advanced packaging and testing is growing day by day. They become more and more important. For mature nodes, investment is expected to continue at the current level.
Driven by those factors, CY 2026 WFE market size is expected to hit a record high. We expect expansion of demand for high-value-added, cutting-edge equipment in coming years. In the growing semiconductor production equipment market, Tokyo Electron has established an advantage to strategically capitalize on diversified business opportunities, as we offer not only front-end process tools for device scaling and device stacking, but also 3D heterogeneous integration tools and testers. There is a consensus that in the year 2030, the semiconductor market will reach $1 trillion in size. Among various technology innovations for 2030, Tokyo Electron has a lot of business opportunities. For example, for etching, due to growing investment in HBM featuring numerous interconnect layers, we expect the sales of JPY 500 billion in total for DRAM interconnect process by year 2030.
For bonder and other 3D integration tools, we generated sales of about JPY 30 billion in the previous fiscal 2025. From now on, however, drastic expansion is expected in applications of advanced logic, DRAM, and NAND, and accordingly, we expect to generate sales of more than JPY 500 billion by year 2030. Tester demand is growing more than expected. Looking back at Tokyo Electron's history, there was a time when prober business made up bulk of our sales. The current tester momentum is just like that time. In the case of advanced probers for AI and HPC, where Tokyo Electron has a high market share, along with the increase of test time and test process, as well as the introduction of new test methods such as live prober, a high growth rate of CAGR of more than 15% is expected between 2025 and 2030.
We are also focusing our efforts on penetration to new business areas and SAM creation. For die probers, whose market size is expected to account for 10%-15% of total prober market, we have achieved agreement with customers to initiate evaluation for development. For logic of future generations, single-wafer plasma-enhanced CVD is expected to boost business opportunities for void-free gap fill. The market size of plasma-enhanced CVD is currently about JPY 1 trillion. The gap fill business is expected to grow to about 10% of this market. Tokyo Electron has succeeded to develop damage-free gap fill deposition technology, and we have started evaluation with leading-edge customers to expand the application of this technology. There are more projects going on very well. For low-resistant metal film deposition, evaluation is going smoothly at multiple DRAM and NAND customers, and we won POR from one customer.
For cleaning equipment, we are making good progress in SPM vapor cleaning and system to clean both sides of wafers simultaneously, which leads to our market share enhancement. For etching, in addition to the business growth of DRAM capacity, for which we are in a dominant POR position, customers will start investment in mass production of NAND with 400 layers at the end of next year. Accordingly, our cryogenic etching system will be deployed into high-volume manufacturing lines, driven by market growth and our share increase. Gross potential expanding significantly will actively promote customer engagement activities and forward-looking R&D activities and strive to continually enhance our corporate value. Next, I will present the financial estimates. Reflecting the result of the first half of this fiscal year, we have revised our financial estimates.
For the full year fiscal 2026, we expect net sales of JPY 2,380,000,000,000 , gross profit margin of 45.3%, and operating profit margin of 24.6%, as shown here. In the ongoing third quarter, we sold some of the shares we own and recorded extraordinary income. Taking these factors into account, we have revised fiscal 2026 net income upward by JPY 44 billion- JPY 488 billion. Now, this slide shows fiscal 2026 SBE new equipment sales focused. The SBE new equipment sales in the second half of this fiscal year remained unchanged from three months ago, as expected grow slightly from the first half to JPY 880 billion. The breakdown by application is shown on this slide. This shows our plan for R&D expenses and CapEx.
In this fiscal year, following completion of Miyagi New Development Building in April, construction of a new development building in Kumamoto was completed this month, October. A production and logistics center in Iwate is also planned to be completed next month. In Miyagi, we also started construction of a new production building in June, which adopts the next-generation smart manufacturing concept. R&D expenses in fiscal 2026 are slightly revised to JPY 290 billion. The plan for CapEx and depreciation remains unchanged, expected to be JPY 240 billion and JPY 86 billion, respectively. This is my last slide showing the dividend focus. Reflecting the revised financial estimates and selling of some shares we own, the full-year dividend per share is expected to be JPY 533.
In this fiscal year, while taking account of balance between status of cash on hand and capital efficiency during this fiscal year, we will flexibly consider the possibility of share repurchase. This concludes my presentation. Thank you very much for your kind attention. Now, we'd like to start the question-and-answer session till 6:00 P.M. Japan time. You can ask questions either in English or Japanese, but our speakers are on the Japanese channel. Please allow us to take audio questions only in Japanese. If you ask a question in Japanese, please click the raise-hand button on the Webex. For details, please refer to the instructions attached to the invitation email. I will call the name of the person one by one. Our secretariat will contact you in advance, so please check the Webex chat box. When asking a question, you are kindly requested to unmute your microphone for yourself.
When your question is answered by our attendees, please hit the raise-hand button again to remove the raise-hand signal. For questions in English, please use the Webex chat box and give your affiliation, name, and question in text, and send it to our secretariat. We will refrain from answering questions if your name or affiliations are not given. We will translate your English question, and on the Japanese channel, we will read it out in Japanese, and speakers will answer in Japanese. On the English channel, the question and answer will be simultaneously interpreted into English on a real-time basis. As we'd like to take questions from as many participants as possible, we will take one question per person. If time allows, we will take additional questions. The first question. Yoshida-san from CLSA Securities. Thank you very much. WFE market focused.
Next year, for DRAM, you made some comments, but once again, as a whole, WFE market, how do you view next year's WFE market? Also, by application, could you share your image of the growth rate? In the first half of next year, your competitors say the sales will be the market should be flat and recovery starting in the second half of next fiscal year. What should it be? What is your view? Thank you. WFE market focused or Outlook. At present, we are now scrutinizing the WFE market trend. You can see quite strong inquiries, especially for the leading-edge nodes for AI server. We have rather strong inquiries. In particular, DRAM is expected to grow double-digit. That's how I view for next year. The strong, very strong demand for AI server is now coming. However, there is one thing I want to note.
Although demand is rather strong, the customers' fab space is limited against the very, very strong demand. So, fab space of customers might have some limitation. We have strong inquiries, but in the second half, recovery is expected because once the open space is available in the customers' fab, they will have process tools moving to the new open space in their fab. For this year, logic and memory proportion should be 35% for memory. Out of memory, 80% is from leading-edge memory and 20% from non-advanced memory. Out of 65% logic, non-memory, 25% is leading-edge, and 75% is non-leading-edge. In the breakdown next year, the memory and non-memory proportion should be 40% - 60%. Maybe in the future, and memory, 85% is from the leading-edge memory. As for logic, for this year, 25% is from leading-edge, but next year, about 40% of total logic are leading-edge logic next year.
Thank you very much. I have one short follow-up question. Next year, this past half of next year, if the market remains flat, now you have the January to March, you can see some drop expected. If there is no change, April to June, you can see drastic recovery in next fiscal year. My view is correct, or as you said earlier, we need to wait for the second half because there is no open space. I think inquiries are rather strong for next fiscal year, so delivery adjustment is now being conducted. AI server demand is growing, so now we can see the timing of recovery. The market is now moving as we expected, so we can have a great expectation for next year. Thank you very much. Yoshida-san, thank you very much for your question. Next question is from Mr. Nakamura of Goldman Sachs Japan.
Thank you very much. I am Nakamura from Goldman Sachs Japan. Thank you very much. Can you hear me? Yes. Three months ago, the calendar 2026 WFE market was drastically revised, and after that, various open AI news and memory market has been booming. There were the drastic changes over the past three months. You said there are strong inquiries, and once again, three months ago, when you made downward revision, there are some factors for that downward revision. How do you view those factors right now? In particular, in some memory customers, you said the yield has been improved, and because of that, you declined the WFE market outlook in the first half of next calendar year. How do you view the current situation? Initially, we had expected early recovery.
That's the reason why we need to make the revision, but three months later, you can see some momentum gaining now. We landed the first half of this fiscal year with the results in line with our focus. We received the orders and had fixed the production plan. I think we can fulfill the plan. Initially, we had the expectation for early recovery. That's the reason why we need to make the downward revision three months ago, but now we can see some symptoms for recovery. Initially, we expected early recovery both for logic and NAND market. Currently, you can see some growing trend of PC and smartphone demand. Initially, we expected a bit too early recovery, and the demand for the mature node has been desecrated. Because of that, we came up with downward revision three months ago.
For mature node market, also in the future, maybe the investment remains unchanged. For leading-edge AI server-related area, the market will be growing. Therefore, a portion of the mature node will be declining gradually. Did I answer to your question? Thank you very much. Calendar 2026 WFE market trend. When you say your current comment, six months ago, you said you expect double-digit growth, and three months ago, you retreated that comment. What is your view for WFE market 2026 calendar year? WFE market is expected to hit the record high in calendar 2026. For memory demand, it is really big, drastically big. Against that big demand, we may not be able to fill the demand, so we may see memory shortage. In that sense, long-term super cycle might start. Also, customer production plan should be closely watched.
In that sense, when customers' FAF capacity is ready, in the second half of next year, you can see another jump in the business. This is one of the ways to view the next year, and I feel comfortable about that kind of outlook. Demand is growing, definitely. Deliveries have started. Even that, the supply cannot catch up with the demand, so we need to carefully watch the capacity enhancement. Thank you very much, Nakamura-san, for your question. Next question is from Mr. Wataki of Morgan Stanley MUFG Research Japan. I'm sorry, I was not able to connect rightly. I think the atmosphere in the market is improving. Next market, it may be difficult. Maybe 20% growth can be achieved, excluding China. How do you view the market growth next year, Kawai-san? Rather high growth rate can be expected.
Actually, my expectation is not so accurate, so I think I feel a very good condition. Even if 20% grow outside of China, depending on Chinese market, overall situation might be rather difficult. ASML is not so good in China next year. How do you think about the outlook of China? In principle, certain levels of semiconductor devices, including commodity devices, are required. Therefore, certain levels can be maintained. However, I cannot hear any bright news. My concern is the restriction, risks of regulations. How do you view the risks of regulations? Compared with the previous period, there are quite a few considerations. As far as our company is concerned, we haven't identified anything additional. We must closely watch the situation of regulations. When we ship equipment from Japan, there are quite a few equipment shipped from Japan. We must abide by the Japanese regulations continuously.
This is how I view the trend. However, the portion of the Chinese market is different from the geopolitical viewpoint. The AI server proportion goes up, the leading-edge area portion is increasing. Therefore, the general proportion of the China market will be declining. Thank you very much. That was very helpful. Wataki-san, thank you very much for your question. Next question is from Shimamoto-san of Okasan Securities. Shimamoto-san, please go ahead. Thank you very much. I'm Shimamoto from Okasan Securities. Thank you very much. My question is a bit different from other questions so far. Next fiscal year is the final year of the midterm management plan, and sales target is JPY 3 trillion. You haven't removed this target, but the market has been improving so far. Your milestone target, how do you view this midterm management plan target? As for the growth rate, growth rate is expected rather high.
How do you view the trend? For our midterm management plan, ever since its announcement, there have been various changes in macroeconomy, geopolitical situation between America, China, regulations, inflation, Russia-Ukraine war. There are quite a few things happening over the past three years. There are some differences from our original assumption. For some equipment, in the beginning, there are some regulations imposed on some of the equipment. Those changes or differences have some impact on our performance of the achievement of financial model. Having said that, high value-added leading-edge equipment, the evaluation is going on track. By providing high value-added equipment, we do have the strong earning power. Excluding macroeconomic impacts as well as our strategy is concerned, I think we are now fulfilling our strategy smoothly. 40% gross profit margin five years ago has been increasing to 45% along with the provision of high value-added products.
In the future, in the leading-edge area, our technology is provided to more and more opportunities. As I said earlier, there are various factors, but we try to offset those impacts because of the strong demand for AI servers. Therefore, if the WFE market grows to a certain expected level, I think we may get close to our midterm management plan. We should closely watch various factors to pursue the possibilities. Thank you very much. I have one follow-up question. For memories, there are some big fluctuations in memory. I think that is the critical issue, especially NAND. For the time being, there has been no investment for NAND, but customers' utilization goes up and NAND price goes up as well. Appetite for investment on page 13. Now you have increased. There is no increasing inquiries, but do you have a high expectation next year for inquiry for NAND? Right.
Yes, definitely. I think next year is a good year for NAND. Strong year. Thank you. Thank you very much. Shimamoto-san, thank you very much for your question. Next question is from Mr. Hirakawa of BofA. I am Hirakawa from BofA. Thank you very much. The field solution business, now we have JPY 160 billion, one step higher. That's what you showed us. Over here, it's not green field, but brown field. That's the reason why it goes to JPY 160 billion toward next fiscal year. I wonder WFE market growth, that figure will be declining, or do you think JPY 160 billion should be a new standard? For customers, utilization rate is increasing. Therefore, field solution is growing accordingly. That's one thing. Leading-edge node, the customer assets should be upgraded. CIP continuous improvement project. It's a kind of upgrade or modifications. Will be rather high in volume.
We do have demand for CIP. Etching system, for example. In our company, customers asking for upgrade from RK4 to RK7. These are the drivers. Thank you very much. I have one follow-up question. If that is the case, second half of this fiscal year or the next fiscal year, the field solution. Is JPY 160 billion, should be a kind of standard. Is that correct understanding? In the future, increasingly, the install base creates the new value. Field solution modifications and uptime improvement of the equipment. Also yield enhancement, which is really critical. Therefore, how can we support our customers to enhance the yield? Or how can we provide the services and technology to support customers to improve yield, which has become more and more critical? Therefore, the field solution sales is expected to grow along with the increase of the install base growth. Thank you very much. Mr.
Hirakawa, thank you very much for your question. Next question is from Yamamoto-san from Mizuho Securities. Yamamoto-san, go ahead, please. I am Yamamoto from Mizuho Securities. Thank you very much. Cost control. I have a question regarding cost control. Tokyo Electron is working hard to grow. That's your direction. You have the company-wide power to promote the growth. I know your driving power is very strong. In some cases, your focus is not correct upward or downward, but for the growth, you have very strong. When your performance is in downturn phase, why don't you think about streamlining your structure rather than bloating? This could be a good opportunity to stop and look back. That's how I view your company's trend. Even under the leadership of Kawai-san, the cost cut is not so much.
Initially committed gross profit margin of 47%, and gross profit margin in the midterm management plan is higher than that. I thought you couldn't reduce costs in the previous guidance cut, including SG&A ratio. Three months later, you could only reduce costs this much. There is a wide gap in profit margin against what is committed to the capital market. Even under the leadership of Kawai-san, you are not able to change the corporate culture. I don't think in that way. I want to say that. For one thing, our employees are a source of value creation. Actually, investment for human resources is equal to the investment for further growth. That's our management policy. For the future, the semiconductor market is growing based on that growth, $1 trillion. We want to have the steady preparation. To prepare for the $1 trillion semiconductor market.
Short-term, midterm, and long-term strategy for growth should be considered carefully. Ever since cancellation of integration with Applied Materials over the past 10 years, our sales have been increased more than four times, about four times. Our profit has been increased by eight times. From now onward, $1 trillion market or more than that. That is the new era. Therefore, we are now working on the R&D investment, CapEx, and human resource investment. We do have plans for that to prepare for $1 trillion semiconductor market. We are now preparing for that. Based on such assets, we want to make the best use of our assets so that we can enhance our capability for the device market, which is to be doubled for a short time. We have the performance-based bonus to have the downside flexibility. Now we have the huge market next year and two years from now.
We must follow. Otherwise, we are not able to address customers' requirements. On the other hand, when it comes to efficiency, digital transformation should be utilized. For example, robotics. DX manufacturing with AI and robotics. Using the current assets, we should be prepared for the sales to be doubled in the future. We would like to exceed the midterm management plan in terms of the operating profit margin. This is the growing industry, and this growing industry is security quality. The financial crisis or IT bubbles or cloud, COVID-19. There have been many events in the past. We should be capable of a dynamic capability to cope with various changes or events in the market so that we can achieve world-class profit margin. Competitors are now working on various initiatives. We are aware of that. Under such strategy, we try to further enhance our profit margin.
Your target or ultimate goal is rather high, so you do not have to worry about short-term turbulences, right? Three-year or four-year, five-year ahead, we should closely look at the future. We also need to think about our employees' work-life balance and work-life balance of supply chain as well. If the market is flat, things are different. Actually, our industry is a growing industry. Short-term, midterm, long-term perspectives should be respected when we run the operation of our company. Thank you very much, Mr. Yamamoto, for your question. Next question is from Mr. Nakanomyo of Jefferies Japan. I am Nakanomyo of Jefferies Japan. Can you hear me? Yes. Thank you very much. I have two questions. Number one, on slide 14. Now you are talking about the Bonder laser. You said JPY 300 billion. You said JPY 500 billion by year 2030.
That means JPY 100 billion per year is achieved somewhere in the future, maybe 2026. Mainly driven by NAND wafer bonding, according to my understanding. Could you elaborate. JPY 500 billion for bonder laser? Could you give me some breakdown, please? At present, the momentum is rather strong. HBM, high bandwidth memory, is now coming. And logic, backside PDN, for example. Quite a few applications are now expanding for bonding. Bonder, the bonder, temporary bonder, the bonder. Laser trimming, extreme laser liftoff, their applications are expanding. Wafer to wafer stacking is also coming. Next fiscal year, we can expect the drastic growth in this area. When it comes to applications, not only expansion of applications. HBM, we do have the strong position as a company. That is expected to expand other companies. Maybe we can enhance the share.
Application expansion, market expansion, and share increase, by those three factors, we can see the drastic growth in this area. Of course, step-by-step, growth will be followed. By year 2030, quite large market will become one of our pillars. You do not have any figure for next year's sales. You cannot say that today. I want to say, but I am sorry, let me refrain from saying any figures. Another question, very similar question, I am sorry, for NAND. To DRAM, it is expected to have double-digit growth, but what is the NAND growth rate? For this year, last year's market was rather low. Actually, your sales for NAND customers should be growing considerably. Next year, the investment for NAND with 400 layers will start, maybe with high confidence level, maybe double-digit, maybe high teens growth is expected for NAND.
Through the penetration of generative AI, storage of servers require NAND, and NAND demand will be going up, I think. In 2022, we hit the record high of JPY 340 billion. Can you see very similar? I want to see the growth rate of NAND in year 2026. Figures will have been increasing gradually. Next fiscal year, we can have a high expectation for NAND. NAND with 400 layers, the NAND WFE is expected to grow drastically. From the second half of next calendar year, investment for mass production of NAND with 400 layers will be growing gradually. I think NAND market is better than this year, and we can have high expectation in 2026. Mr. Yatsuda, do you have any comment? At present, for inquiries, the data center, the nearline demand is now growing. PC and smartphones, that is the major market of NAND.
Actually, the PC and smartphones market is rather soft, but migration investment will continue next year as well. Investment for 400 layer NAND is highly expected. When the demand for PC and smartphone increases, you can see the capacity enhancement investment for NAND. For the time being, there is no symptom of the increase of the demand for NAND in the smartphone or PCs. Therefore, we cannot give you any specific numbers now. Thank you very much, Mr. Nakanomyo, for your question. Next question is from Mr. Yoshio Oka of Nomura Securities. Thank you very much. I am Yoshio Oka of Nomura Securities. Thank you very much. Thank you very much for your presentations. Again, on page 14, I have a question regarding page 14. This is just the clarification. So ECHA. JPY 500 billion more in total by 2030. What is your accumulative sales so far?
I want to get the number for that. And the same line for Prober. You are expecting to grow the Prober, but your competition, competitor is rather strong for HBM. Your company, in order to achieve the K-goal of 15% or more, the market is expected to grow furthermore, or do you improve the share? Are there any factors for you to increase your share? I want to see how the Prober business grows. For etching system, the DRAM interconnect process. Along for HBM, investment increase is expected. Not only HBM, for DRAM, there is the investment growth, but interconnect process, in the case of HBM, will be four times more. Therefore, rather stable, strong growth is expected. That is the reason why JPY 500 billion or more. That is what we want to say. Simply calculating about JPY 100 billion per year.
Simply calculating, but getting closer to 2030, the sales will be growing gradually. In addition, for capacity edge, we are in the dominant positions for major customers. Therefore, that will bring us the big business opportunities. As for Prober, when it comes to Prober, in particular, cutting-edge logic, our position there is rather strong. The leading-edge logic, in the area of leading-edge, we are a dominant position. Our share is increasing steadily. That application, the test, for that application, the test time and test volume are increasing steadily. That has a strong momentum. AI server demand increases accordingly. The Prober business grows rapidly with the K-goal of 15% or more. K-goal 15% or more increase by Prober. By Prober, for the future, it is expected to grow, accounts for 10%-15% of the entire Prober market. We agreed with our customers on the evaluation for development.
If they are in progress, we may have some opportunity to make some announcement. We have consensus with customer, agreement with customer to conduct evaluation for development. We can expect the good growth. Thank you very much for your answer. Thank you very much, Mr. Yoshioka, for your question. Next question. In text. Let me read it out. The first question is from Mr. Rolf Bulk of New Street Research. You mentioned in your prepared remarks, mature node WFE spending is expected to remain roughly flat at current levels. Does this include or exclude Chinese investment? What do you expect for Chinese WFE spending growth next year? What is your level of confidence or visibility on this? Thank you very much for the question. For mature node, yes, China is included. China is included. We need to take account of various things.
When it comes to future outlook, maybe flat, including China. Mature node market remains flat, including China. That should be the appropriate way to view the future. WFE market is driven by AI servers. The cutting-edge technology, that is the major driver. That is where we must provide high-value added products with good strategy. Stable and continual growth is expected. Thank you very much. Thank you very much, Mr. Bulk, for your question. Next question is from Lie Ping Huang of Huatai Securities. Management highlighted advanced packaging as a key growth driver in the past. Could you introduce what is the progress in this area and quantify current revenue contribution from equipment sold into advanced packaging applications and the future target? For the advanced packaging, the Bonder and the Bonder and Prober related products are rather important.
Bonder, the Bonder, and Prober is, the two years, our sales have been tripled, and we achieved about JPY 30 billion last year of the sales. When you refer to page 14, as I said on page 14, the Bonder, the Bonder, five years to come, we are going to achieve the cumulative sales more than JPY 500 billion. That is our plan. This plan really reflects the high potential. Advanced packaging or integration or heterogeneous integration is expected to grow furthermore on page 14. I already talked about that, including our expectations. Thank you very much, Mr. Huang, for your question. Next question is [Tommy Key] from [Brandenburg Securities]. Let me read it out. You mentioned the leading-edge logic country investment will accelerate. Will leading-edge country logic grow significantly next year, year over year? Driven by which node, 3 nanometer or 2 nanometer node?
Which node will drive the growth? Will all the foundry and logic players CapEx up year over year, or only one or two players will invest? Where China bottoms back to 20% issue of your revenue at some point? Thank you very much for your question. Currently, it is flat and mature node, and that covers China market. That is what I said earlier. In the future, high-end nodes for AI server will drive WFE market growth. Let me answer to your last question. I am sorry. 30% or less, that is rather high. Highly likely that the China proportion will go below 30%. Talking about your earlier questions, the logic or leading-edge node is expected to grow. Yes, we need to scrutinize the figures of percentage, but we do receive the strong inquiries. Therefore, we expect the growth, strong growth. Any other questions I should answer?
The general ID nodes. It depends on customer's situation. We are suppliers, so we are not able to give you any comments because we are suppliers. We need to be ready to fulfill the customer's demands and make some contribution. Thank you very much, Akisan, for your question. No more questions. Since there seems to be no more questions, we would like to conclude or close the financial announcement. Lastly, we'd like to continually improve our IR activities based on your precious feedback.
