ASML and US chip stocks tumble after report of China's DUV lithography breakthrough
Concerns over growing competition from Chinese-made chipmaking tools hit semiconductor shares, with ASML falling 4.6% and the Philadelphia Semiconductor Index dropping 3.59%.
Shares of ASML and major US chip stocks fell after a report indicated that China had begun mass production of its own deep ultraviolet (DUV) lithography tools, reigniting concerns over competition from Chinese chipmaking equipment.
According to The Information, China has started making homegrown DUV chipmaking tools, a development that could reduce its dependence on foreign suppliers like ASML.
4.6%
The broader semiconductor sector also suffered. The US Philadelphia Semiconductor Index (SOX) closed at 11,394.40, down 3.59%, as the news stoked fears of increased competition from Chinese manufacturers.
Among individual companies, Intel's second-quarter financials showed operating cash flow positive, but adjusted free cash flow was negative $8.4 billion. The company also spent $14.2 billion buying out its Ireland fab partner on 40-year paper at over 6%.
Key levels for the SOX. The invalidation level for a bullish call is a monthly reclaim of 14,246.96. Overhead resistance stands at 13,291.75 and 13,876.77, while projected downside targets are 9,839.79 and 9,755, with further potential to 7,095 into year-end.
Investors are also looking ahead to earnings reports from major tech companies. Microsoft and Meta are set to report after the close on July 29, followed by Amazon on July 30.
Updates
Shanghai Aishengna Electronic Technology Group has emerged as the state-backed firm leading China's effort to mass-produce immersion DUV lithography tools, aiming to manufacture five units in 2026 and scaling to approximately 20 by 2027. While analysts note these domestic machines currently trail ASML’s systems in performance, yield, and reliability, the development offers Chinese chipmakers a potential alternative as export restrictions continue. Meanwhile, following the initial report, ASML shares saw significant volatility with conflicting reports on the total market value impact, while other sector firms including BE Semiconductor and Infineon also recorded notable declines.
Shanghai Aishengna Electronic Technology Group has emerged as the state-backed firm leading the effort to mass-produce immersion DUV lithography tools, with plans to manufacture five units in 2026 and expand to approximately 20 units by 2027. While Chinese chipmakers view this as a potential safeguard against tightening export controls, analysts note that the machines currently lack the performance, yield, and reliability of ASML systems, making short-term commercial competition unlikely. Separately, reports indicate that shares of ASML and other sector peers faced additional volatility, with market fluctuations continuing as stakeholders weigh the long-term implications of China's drive for semiconductor self-sufficiency.
State-backed Shanghai Aishengna Electronic Technology Group is leading the mass production of these immersion DUV tools, aiming to deliver five units this year and approximately 20 in 2027. While Chinese chipmakers may prioritize these domestic machines to mitigate risks of future U.S.-led export restrictions, analysts caution that the units currently lack the performance, yield, and reliability of ASML systems. Consequently, experts note that producing a small number of prototypes does not equate to the high-volume manufacturing capabilities required to pose a significant short-term commercial threat to ASML's global operations.
The state-backed firm Shanghai Aishengna Electronic Technology Group has emerged as the lead developer for China's mass production of immersion DUV lithography tools, aiming to manufacture five units this year and approximately 20 by 2027. While analysts note that these domestic machines have yet to achieve the performance, reliability, and yield levels of ASML's systems, the initiative represents a significant strategic step toward Chinese semiconductor self-sufficiency. Industry experts emphasize that the long-term competitive risk to ASML's market share remains uncertain, as China's effort faces substantial hurdles regarding production scalability and technological parity with established global leaders.
State-backed Chinese firm Shanghai Aishengna Electronic Technology Group is spearheading the mass production of domestic immersion DUV lithography units, with targets to produce five machines this year and approximately 20 in 2027. While analysts note that these domestic tools currently lack the performance, yield, and reliability of ASML’s systems, the development serves as a strategic move for China’s semiconductor self-sufficiency. Furthermore, the market impact has been significant, with ASML shares falling up to 8% on Monday and approximately 17% from recent highs, as investors weigh long-term risks to the company's revenue in China, which accounted for 16% of sales in the first half of 2026.
The state-backed firm Shanghai Aishengna Electronic Technology Group is leading the mass production of these immersion DUV tools, aiming to deliver five units this year and approximately 20 in 2027. While analysts note that the short-term commercial threat to ASML is low due to limited initial volumes and performance gaps in reliability and yield, the development signifies a major push for Chinese semiconductor self-sufficiency. Meanwhile, market volatility continues as ASML shares fell as much as 8% on Monday, and China's share of ASML’s total revenue is now projected to be around 20% for this year.
State-backed Chinese firm Shanghai Aishengna Electronic Technology Group is leading the mass production of immersion DUV lithography tools, with plans to produce five units in 2026 and approximately 20 in 2027. While these machines represent a significant step in Beijing's semiconductor self-sufficiency initiative, analysts emphasize that they currently lack the performance, reliability, and production yield parity of ASML systems, and will require extensive testing and iteration to be viable for high-volume manufacturing. Furthermore, ASML's revenue exposure to China is estimated at 20% for this year, and the company maintains a robust outlook despite the emerging competition and ongoing U.S. export control debates.
State-backed Chinese firm Shanghai Aishengna Electronic Technology Group has emerged as the lead entity for mass-producing immersion DUV lithography tools, aiming to manufacture five units in 2026 and approximately 20 in 2027. While these machines represent a significant step toward Beijing's semiconductor self-sufficiency, experts emphasize that their performance, reliability, and yield metrics remain unproven and currently lag behind ASML’s established systems. Although China accounted for roughly 16% of ASML's first-half 2026 sales, analysts suggest the short-term commercial impact is limited by the new machines' low initial output and the complex technical requirements for high-volume manufacturing.
