China Starts Building Its Own DUV Chip Lithography Tools - Technology Org
China has begun producing domestically developed immersion deep ultraviolet (DUV) lithography machines, expected to be delivered this year to Semiconductor Manufacturing International Corp, Hua Hong Semiconductor and ChangXin Memory Technologies, according to a report citing people familiar with plans. Initial output is small (about five machines in 2025, ~20 in 2027). ASML shares fell over 7% and equipment suppliers also dropped.

The 30-second read
Why it matters
The report frames domestic immersion DUV as an alternative source of critical lithography equipment amid potential tightening of foreign tool exports and servicing constraints, which can affect both equipment demand and maintenance economics.
Market read
A first report of China starting domestic immersion DUV manufacturing, with expected deliveries to major Chinese chipmakers this year, triggered sharp selloffs in ASML and related equipment names.
What to watch
The text notes China is also working on domestic EUV at prototype stage and that yield, uptime, and overlay accuracy will determine adoption. Traders may be over-weighting the headline ramp before commercial viability is proven.
Background
China has faced export restrictions since 2019 that blocked access to extreme ultraviolet (EUV) systems, leaving immersion deep ultraviolet (DUV) as the practical ceiling for leading Chinese fabs.
Ticker impact
ASML is the dominant supplier of immersion DUV lithography, and the report says China has started domestic manufacturing that is expected to reach major Chinese chipmakers this year.
Near term, continued downside pressure is plausible given the article cites ASML shares down more than 7% on the news.
The text links the domestic DUV ramp to export-restriction dynamics and notes ASML’s market dominance, plus it reports a sharp same-day ASML selloff.
Infineon Technologies is mentioned as dropping nearly 3% as the report’s equipment-supply-chain reaction rippled through semiconductor-related names.
Limited company-specific follow-through expected unless additional Infineon-specific exposure is disclosed.
The article does not describe any Infineon business impact, only a price decline.
Market effects
Highlights a potential shift in China’s photolithography bottleneck from imported EUV-constrained tooling toward domestic immersion DUV, which could pressure parts of the lithography equipment ecosystem and servicing assumptions.
Reinforces China-focused semiconductor self-reliance momentum, with potential knock-on effects for European equipment suppliers exposed to China demand.
If domestic DUV scales beyond pilot volumes, it could alter the long-run effectiveness of export controls on advanced lithography tool access and servicing.
Counterpoint
Because the article stresses performance and reliability lag and only small pilot volumes (about five machines this year), the competitive threat to ASML may be delayed and less material than the initial selloff implies.
