China Begins Mass Production of Domestic Immersion DUV Lithography Machines
A state-backed Shanghai company has started mass-producing immersion deep ultraviolet (DUV) lithography machines, with first deliveries expected in 2025-2026 to Chinese chipmakers SMIC, Hua Hong, and CXMT. Output targets are 5 machines in 2026 and 20 in 2027, far below ASML’s 130 systems. The U.S. MATCH Act threatens to cut ASML sales to China, while analysts caution Chinese tools trail ASML in performance and scalability, with commercial viability unlikely until the mid-2030s. ASML shares fell up to 10% on the news.

Why China’s DUV Push Hit ASML and Micron for Different Reasons
China has begun producing domestic immersion deep-ultraviolet lithography tools, with state-backed Shanghai Aishengna planning to deliver machines to SMIC, Hua Hong, and CXMT. Production is small (5 systems in 2026, 20 in 2027) and performance still trails ASML. ASML faces direct product substitution risk as DUV scanners are the main lithography available to China under export controls, with China generating 29% of ASML's 2025 net sales. Micron faces indirect supply-curve risk through competitor CXMT, which could add DRAM capacity and pressure pricing. However, Micron's strong fiscal Q3 results ($41.46B revenue, data center >$25B) and current supply-demand dynamics mitigate immediate bearish impact. The article also notes hedge fund positions and short interest data for Micron.
Can China Replace Lithography Powerhouse ASML?
A report by The Information, later confirmed by Reuters, revealed that a state-backed Chinese firm, Shanghai Aishengna Electronic Technology Group, has begun mass-producing deep ultraviolet (DUV) lithography machines, a technology long monopolized by Dutch giant ASML. The news triggered a roughly 9% drop in ASML shares this week. However, analysts at JPMorgan and Bank of America caution that the selloff is overblown, noting that the Chinese firm's production volume is tiny compared to ASML's (which shipped over 131 UV machines last year and plans 30% capacity increases). More critically, China has not yet developed extreme-ultraviolet (EUV) lithography, essential for leading-edge AI chips. JPMorgan acknowledged a long-term risk to ASML's China revenue, which accounts for about 20% of sales ($10 billion).
China's Homegrown Chip Tool Push Squeezes ASML Between US Export Controls and Beijing's Self-Sufficiency Drive
A Reuters report reveals that China's state-owned Shanghai Aishengna Electronic Technology Group is leading an effort to mass-produce immersion deep ultraviolet (DUV) lithography tools, key to modern chipmaking. This development highlights how ASML, Europe's most valuable listed company, is caught between U.S. export controls limiting its access to the Chinese market and Beijing's push for technological independence. ASML's shares fell about 10% in two days, wiping over €60 billion off its market value. While JPMorgan analysts argue damage will be limited in the medium term—ASML shipped 131 such systems in 2025 versus China's plan for 5 this year and 20 in 2027—the long-term risk to ASML's China revenue is rising. Analysts note that U.S. export controls have inadvertently created a business case for Chinese lithography, as Chinese chipmakers may accept less capable domestic machines to avoid dependence on foreign tools that could be blocked later. ASML expects 20% of its 2026 revenue, around €9 billion, to come from China despite existing restrictions.

China's Homegrown Chip Tool Push Squeezes ASML Between US Export Controls and Local Competition
A Reuters report reveals that China's state-owned Shanghai Aishengna Electronic Technology Group is leading an effort to mass-produce immersion deep ultraviolet (DUV) lithography tools, a key component for modern chipmaking. This development highlights how ASML, Europe's most valuable listed company, is caught between U.S. export controls limiting its sales to China and Beijing's push for technological self-sufficiency. Following the report, ASML shares fell about 10%, wiping over €60 billion off its market value. While ASML dominates the DUV and EUV lithography markets, analysts note that China's initial production volumes (5 tools in 2026, 20 in 2027) are far below ASML's 2025 shipments of 131 systems, limiting medium-term damage. However, the long-term risk to ASML's China revenue—expected to be 20% of total revenue in 2026—is rising. Experts argue U.S. export controls have inadvertently created a business case for Chinese lithography, as Chinese chipmakers may accept lower productivity from domestic tools to avoid future supply disruptions.
ASML shares drop 5% on reports of Chinese rival making DUV lithography breakthrough
ASML, Europe's most valuable tech company and the sole global producer of extreme ultraviolet (EUV) lithography machines essential for advanced chips, saw its shares fall nearly 5% in premarket trading after reports emerged that a Chinese state-backed firm has begun manufacturing immersion deep-ultraviolet (DUV) lithography machines. While the Chinese DUV machines are at an early stage and not yet comparable to ASML's technology, the development signals a growing threat to ASML's dominance in the DUV market, which has seen surging demand due to the AI boom. China plans to produce only 5 DUV machines this year and 20 next year, far behind ASML's expected 130 shipments. The news adds to ongoing tensions as ASML is barred by US and Dutch regulations from selling its most advanced EUV machines to China. ASML has also announced plans to expand EUV manufacturing capacity, including supply for Elon Musk's proposed $55 billion Terafab semiconductor plant.
China's reported chip tool breakthrough raises questions about ASML competition
A report emerged that an unnamed Chinese company has begun mass-producing an immersion deep ultraviolet (DUV) lithography machine, a key chipmaking tool long dominated by Dutch firm ASML. The tools are expected to be delivered this year to China's top chipmakers, including SMIC and CXMT. ASML's stock fell 1.8% amid a broader semiconductor sell-off, but analysts caution that China's technology faces significant hurdles. Key concerns include whether the Chinese DUV machine can achieve yield parity with ASML's tools, and whether production can be scaled. Analysts note that ASML's decades of iteration and reliability are hard to replicate, and that Chinese foundries using imported ASML machines still lag behind TSMC. The breakthrough is seen as potentially limited to low-end chip manufacturing, unlikely to shake ASML's dominance in the near term.
China Begins Mass Production of Domestic Immersion DUV Lithography Machines, First Deliveries Expected in 2026
A state-backed Shanghai company has begun mass-producing immersion deep ultraviolet (DUV) lithography machines, with first units to be delivered this year to Chinese chipmakers SMIC, Hua Hong Semiconductor, and memory maker CXMT. Output targets are around five machines in 2026 and roughly 20 in 2027. The manufacturer, reportedly drawing teams from several Chinese firms including Shanghai Yuliangsheng Technology, uses mostly domestic components but relies on some critical Japanese parts. The development comes as the U.S. MATCH Act, moving through Congress, would statutorily cut off ASML sales and servicing to these Chinese firms. ASML expects to ship about 130 immersion systems in 2026, with China accounting for around 20% of net sales. Independent analysis suggests commercial-scale Chinese immersion DUV may not be viable until the mid-2030s, and the new machines trail ASML's tools on performance and build quality.

China Begins Mass Production of Homegrown Immersion DUV Lithography Machines, First Deliveries Expected This Year
A state-backed Shanghai company has begun mass-producing immersion deep ultraviolet (DUV) lithography machines, with first units to be delivered this year to SMIC, Hua Hong Semiconductor, and memory maker CXMT. The manufacturer, reportedly pulling teams from several Chinese firms including Shanghai Yuliangsheng Technology, aims to produce about five machines in 2026 and roughly 20 in 2027. Most components are domestic, though some critical parts still come from Japan, and local supplier delays have held back output. The development comes as the U.S. MATCH Act, moving through Congress, would statutorily cut off ASML sales and servicing to these Chinese firms. ASML expects to ship about 130 immersion systems in 2026, with China accounting for around 20% of net sales this year, down from 33% in 2025. Independent analysis projects commercial-scale Chinese immersion DUV in the mid-2030s, with ASML holding 98.7% of the immersion market. Qualifying the new machines for production lines could take many months, and they trail ASML's tools on performance and build quality.
