China’s 50% domestic equipment mandate pressures AMAT’s $4.2B annual China revenue, while new domestic DUV systems directly threaten ASML’s installed base.
CXMT could surpass MU in physical wafer capacity by 2030, sourcing between 40 and 50 percent of tools from domestic suppliers including ACMR rather than AMAT.

China has directed semiconductor manufacturers to use at least 50% domestically produced equipment when adding new capacity, according to a Reuters report citing people familiar with the policy. Fab projects that fail to meet that threshold are generally denied regulatory approval, although flexibility remains where no suitable Chinese tool is available. The requirement favors domestic equipment suppliers such as Naura Technology and AMEC over foreign companies and provides the context needed to understand China’s newly announced immersion deep-ultraviolet lithography systems.
Reports that Shanghai Aishengna Electronic Technology Group has begun producing immersion DUV systems sent shares of ASML Holding (ASML) down sharply and contributed to weakness across semiconductor equipment stocks, including Applied Materials (AMAT). The initial reaction treated the development as evidence that China could begin replacing Western equipment across its semiconductor industry. That conclusion is directionally understandable, but the immediate effect on Applied Materials is being overstated.

Applied Materials does not manufacture lithography systems. A Chinese immersion DUV machine competes directly with ASML, not with Applied Materials’ deposition, etch, thermal-processing, metrology, inspection and advanced-packaging systems. The greater risk is indirect and longer term: if domestic lithography becomes commercially usable, it fills one of the largest remaining holes in China’s equipment supply chain and allows Chinese fabs to build production lines containing a higher percentage of domestic deposition, etch, cleaning and chemical mechanical planarization equipment.

For investors, the distinction matters. Five unproven Chinese DUV systems will not materially change Applied Materials’ earnings in 2026. But the combination of China’s 50% domestic-equipment requirement, rapidly growing local equipment companies, and expanding fabs at CXMT, SMIC and Hua Hong could reduce Applied Materials’ addressable market in China over several years.
Applied Materials Remains Heavily Exposed to China
Applied Materials generated $2.095 billion from China during its fiscal first quarter of 2026, representing 29.9% of total company revenue. China remained the company’s largest individual geographic market even though revenue declined 6.6% from $2.243 billion one year earlier.
China exposure held close to that level in fiscal Q2: reported China revenue was $2.087 billion, or 26.4% of the quarter’s $7.910 billion total. Across the first half of fiscal 2026, China generated $4.182 billion of Applied Materials’ $14.922 billion in revenue — 28.0% of the total (Table 1).
These figures do not mean that all $2.087 billion of quarterly China revenue is threatened by CXMT or Chinese DUV. U.S. controls already restrict exports of specified semiconductor manufacturing equipment used to produce advanced chips in China. The thresholds include logic at 16/14nm or below, DRAM at 18nm calculated half-pitch or below, and advanced NAND.
Applied Materials’ remaining China revenue therefore includes portions of the market it can still legally serve: qualifying mature-node fabs, specialty devices, packaging, display-related manufacturing, services and unrestricted customers. Its current China business should not be confused with the advanced memory and logic opportunities from which the company has already been partially excluded — exclusions that carry a real, quantified cost. Applied Materials has guided to roughly a $600 million revenue headwind in fiscal 2026 from expanded U.S. export restrictions, including $110 million in the fiscal fourth quarter alone.
China’s domestic-equipment policy layers a second risk on top of that sanctions-driven one. Chinese fabs are being encouraged to buy local equipment even in markets where foreign tools remain legally available, putting Applied Materials’ permitted China business under competitive pressure while it is simultaneously locked out of the country’s most advanced capacity additions.
Chinese Equipment Suppliers Are Already Gaining Share
China’s domestic equipment industry is no longer a collection of small development programs. Naura supplies deposition, etch, furnaces, rapid thermal processing and other systems. AMEC competes in etch and deposition. Piotech participates in deposition, while Hwatsing Technology supplies CMP equipment. ACM Research (ACMR), through its large Chinese operating presence, supplies wet cleaning, plating, furnace and packaging systems, although its U.S. headquarters and dual corporate structure distinguish it from purely domestic companies such as Naura and AMEC.
Combined sales from six major Chinese semiconductor equipment suppliers increased from $748 million in 2020 to $7.608 billion in 2025 — more than a tenfold increase in five years. Their adjusted worldwide WFE share rose from 1.2% to 6.5% over the same period. These companies collectively grew sales 29.9% in 2025, led by Piotech, AMEC and Hwatsing (Table 2).
Chinese equipment companies do not need to replace Applied Materials worldwide to affect its financial performance — they only need to gain share inside China, where Applied Materials still produces more than a quarter of its revenue. The 50% domestic-equipment requirement gives them a protected qualification environment, while U.S. export controls limit the foreign competition they face at advanced Chinese fabs.
Domestic DUV can accelerate this process even if the scanners initially perform far below ASML’s systems. Lithography has remained one of the largest weaknesses in China’s equipment ecosystem. Progress there makes it easier to assemble a complete Chinese production line rather than pairing Chinese deposition and etch systems with imported ASML scanners.
Five Chinese DUV Systems Do Not Constitute Mass Production
Shanghai Aishengna is reportedly targeting approximately five immersion DUV systems in 2026 and 20 in 2027. Initial deliveries are expected to go to SMIC, Hua Hong and CXMT. By comparison, ASML shipped 131 immersion DUV systems in 2025.
The Chinese systems reportedly use mostly domestic components, though selected critical parts still come from Japan. They also trail ASML’s scanners in performance, reliability and build quality and could require months of testing before entering production. China’s domestic EUV initiative remains at the prototype stage and is likely years from supporting commercial chip output.
Aishengna’s 2027 production target would equal only about 15.3% of ASML’s 2025 immersion DUV shipments (Table 3). The near-term numbers are small, but the planned customers are strategically important: China’s leading foundry, a major mature-node producer and its principal DRAM manufacturer.
“Mass production” therefore overstates the immediate commercial threat. Five systems are closer to a qualification fleet than a volume-production program. The investment significance is not that Aishengna is about to displace ASML across China, but that the scanners will be installed at the fabs most important to China’s semiconductor self-sufficiency strategy — where they can be tested alongside Chinese deposition, etch, cleaning, CMP and process-control equipment. If the resulting production line hits acceptable throughput and yield, later capacity expansions can carry a progressively higher share of domestic tools.
CXMT Demonstrates the Longer-Term Risk
CXMT is the clearest example of how this equipment ecosystem could develop. The company is now the world’s fourth-largest DRAM producer, behind SK hynix, Samsung Electronics and Micron Technology (MU). Its G4 16Gb DDR5 process has an approximately 16nm feature size, placing it within the U.S. advanced-DRAM threshold covering production at 18nm calculated half-pitch or below.
Consequently, Applied Materials cannot freely compete for much of the equipment required for CXMT’s newest DRAM production. CXMT is not simply choosing Naura over Applied Materials in an unrestricted competitive bid. U.S. rules have already limited Applied Materials’ ability to supply and service controlled tools at advanced Chinese memory facilities.
The impact is no longer only theoretical. Industry trackers estimate that domestic equipment now accounts for roughly 40% to 50% of the tools installed on CXMT’s production lines, a share expected to rise as new expansion phases begin. In core processes such as etch, domestic penetration reportedly exceeds 60% at some facilities, although I have not independently been able to verify these figures. Naura, AMEC and other Chinese suppliers, not Applied Materials, are already capturing much of the equipment spending tied to China’s fastest-growing DRAM producer.
This means CXMT’s expansion represents foregone growth as much as direct displacement of Applied Materials’ currently reported China revenue, and the foregone share is already substantial. CXMT’s capacity reached approximately 290,000 wafer starts per month in Q1 2026 and could approach 350,000 by year-end. New fabs under construction in Shanghai and Hefei could eventually lift CXMT’s capacity above 600,000 wafers per month and allow it to overtake Micron in physical wafer capacity by 2030.
CXMT will still trail Micron technologically. Its older process produces fewer bits per wafer, while Micron receives additional revenue from leading-edge DRAM and HBM. However, CXMT’s lower manufacturing efficiency may require greater wafer capacity and equipment intensity to produce a given number of bits. That would normally create an opportunity for deposition and etch suppliers. China’s domestic-equipment policy, and CXMT’s own sourcing pattern, instead directs much of that opportunity toward local companies.
China’s DUV program reinforces this outcome. CXMT has already relied on imported ASML DUV systems and multi-patterning to produce advanced DRAM without EUV. A domestic DUV platform would not immediately give CXMT the same technology as Micron, Samsung or SK hynix, but it could allow the company to add future lithography capacity without depending entirely on additional ASML shipments or foreign servicing.
Applied Materials’ AI Opportunity Remains Intact
The China risk should not obscure Applied Materials’ growth opportunities elsewhere. AI is increasing demand for advanced logic, gate-all-around transistors, HBM, high-performance interconnects, 3D architectures and advanced packaging. These transitions increase materials-engineering intensity and support demand for Applied Materials’ deposition, etch and packaging systems.
The company’s June 2026 product introductions for 2nm and advanced 3D architectures — including its Viva nanosheet engineering platform and new ALD and etch systems — target precisely these AI-related manufacturing transitions. Spending by TSMC, Samsung, Intel, Micron and SK hynix can offset some of the equipment opportunities Applied Materials cannot pursue in China.
China’s five initial DUV systems therefore do not invalidate the Applied Materials investment story; they are too few, too immature and too far behind ASML to produce an immediate earnings shock. The larger issue is whether domestic DUV lets China qualify a complete equipment ecosystem that eventually reaches beyond restricted advanced fabs and begins displacing Applied Materials in the mature-node and specialty markets where it can still sell.
Investor Takeaway
The market reaction to China’s domestic DUV announcement exaggerated the near-term threat to Applied Materials. Aishengna does not compete directly with Applied Materials, and five planned systems will not materially reduce its 2026 revenue. Applied Materials’ most important AI-related growth opportunities remain tied to advanced manufacturing outside China, where its deposition, etch, gate-all-around and packaging technologies retain strong competitive positions.
The longer-term China risk is nevertheless real, and CXMT shows it is no longer only longer-term. Applied Materials generated 29.9% of fiscal Q1 2026 revenue from China, while six major Chinese equipment companies increased combined sales more than tenfold between 2020 and 2025. China’s 50% domestic-equipment requirement gives those suppliers a structural advantage, and CXMT—one of the first planned recipients of China’s domestic DUV systems—already sources an estimated 40%–50% of its production-line equipment domestically.
For investors, the correct interpretation is not that Chinese DUV immediately threatens Applied Materials’ earnings. It is that China has turned its fastest-growing advanced fab into a protected qualification market for domestic processing equipment, and CXMT’s rising localization rate is the clearest evidence of how far that substitution has already progressed. Applied Materials can continue growing through AI-driven investment elsewhere, but a progressively self-sufficient Chinese equipment industry will limit how much of China’s semiconductor expansion the company can capture.
