Investment Rating - The report indicates a positive outlook for the cleanroom sector, suggesting that the demand for cleanrooms is expected to continue increasing due to the semiconductor industry's growth [10]. Core Insights - The cleanroom shortage has garnered attention from various stakeholders in the semiconductor supply chain, including storage, wafer foundries, and equipment manufacturers, indicating a rising demand for cleanroom facilities [8][10]. - Major companies like Micron and Samsung are planning to invest in additional cleanroom capacity to meet the growing demand for advanced memory technologies, particularly HBM, which has a higher wafer consumption ratio compared to DDR5 [10]. - TSMC is also facing capacity constraints in its 3nm production due to high demand from companies like NVIDIA and AMD, leading to an anticipated increase in monthly production capacity despite cleanroom space limitations [10]. - Equipment manufacturers such as ASML, Lam Research, and KLA have reported that the physical capacity of wafer fabs is a significant constraint on expanding production to meet customer demand, with many fabs nearing full operational capacity [10]. Summary by Sections Semiconductor Storage Companies - Micron is shifting memory demand from DDR5 to HBM, which requires more cleanroom space, prompting plans for additional cleanroom investments [10]. - Samsung anticipates supply expansion limitations in 2026 and 2027 due to the scarcity of cleanroom space and is planning to invest in new wafer fabs to secure cleanroom capacity [10]. Wafer Foundries - TSMC is expected to increase its 3nm capacity by an additional 20,000 wafers per month, but is constrained by cleanroom space [10]. Equipment Manufacturers - ASML reported a revenue of €7.2 billion in Q4 2025, with CEO emphasizing that many fabs are operating at near full capacity, limiting new capacity releases due to land, power, and cleanroom space constraints [10]. - Lam Research achieved revenue of $5.1 billion, with management noting that existing fabs have little excess capacity, and new factory construction typically takes over two years [10]. - KLA reported a record revenue of $2.9 billion, with the CEO highlighting customer efforts to increase equipment density and process efficiency within limited space [10]. Market Outlook - The cleanroom sector is expected to see growth in both scale and profitability driven by AI-related semiconductor demand, with recommended investments in companies like Axiom Integration and Shenghui Integration overseas, and Deep Sanda A and Bocheng Co. domestically [10].

Summary of Conference Call Records Industry Overview - The focus is on the cleanroom industry, particularly companies like Yaxing Integration and Shenghui Integration, which are leaders in this sector [1][2]. Key Insights and Arguments - **AI Demand and Capital Expenditure**: Recent financial reports from several overseas leaders have exceeded expectations, confirming the robust demand for AI and indicating that AI capital expenditures are entering an expansion phase. Cleanrooms, as a front-end infrastructure segment, are expected to see a corresponding increase in demand [1]. - **U.S. Semiconductor Investments**: The U.S. has significantly increased investments in the semiconductor manufacturing chain, attracting major companies like TSMC and Samsung to establish factories in the U.S. By the end of 2024, TSMC is expected to have invested $65 billion in the U.S. and announced an additional $100 billion investment in March 2025. Recent "tariff-for-investment" policies have led TSMC and other Taiwanese companies to commit to at least $250 billion in direct investments in the U.S., which is likely to drive rapid growth in regional cleanroom demand [1]. - **Southeast Asia Developments**: - **Singapore**: The RIE2030 initiative plans to invest SGD 37 billion over the next five years in key economic sectors like semiconductors, aiming to double the output of the semiconductor and related manufacturing industries by 2030. This initiative is attracting major players such as UMC, World Advanced, and Micron to establish factories [2]. - **Vietnam and Thailand**: These countries are leveraging labor cost advantages and industrial cluster benefits to accelerate the transfer of precision manufacturing (PCB) and other supply chains, leading to robust regional capital expenditures [2]. Supply Side Dynamics - Cleanroom production capacity is primarily concentrated in mainland China and Taiwan, with the top five companies holding nearly 40% of the market share. Mainland leaders like Shenzhen Sanda A are actively pursuing overseas expansion. However, there are potential restrictions on mainland capacity moving to the U.S., leading to a significant mismatch in supply and demand in the U.S. market. It is anticipated that there will be an accelerated introduction of Taiwanese cleanroom leaders to the U.S. market, with project profit margins expected to exceed expectations, contributing significantly to performance growth. Continuous recommendations are made for Yaxing Integration (a Taiwanese cleanroom leader securing multiple large contracts in Singapore) and Shenghui Integration (which has established a U.S. subsidiary and is expected to benefit from TSMC's orders) [2]. Risk Factors - Potential risks include a downturn in semiconductor capital expenditures, increased competition within the industry, and the possibility that expansion efforts in the U.S. may not meet expectations [3].
