China has brought online a domestic prototype of the EUV (Extreme Ultraviolet) lithography machine, a class previously produced only by Dutch firm ASML. According to Reuters sources, the prototype can generate the ultraviolet light needed to process wafers for advanced chip manufacturing and is operational rather than purely theoretical or lab-stage.
The system still relies on components stripped from older ASML machines. Replicating the highly precise optics produced by Western suppliers remains a major technical hurdle for Chinese engineers. Even so, the prototype targets the key tool for 5 nm, 3 nm and below process nodes. If verified and commercialized, it would be one of China's most concrete steps toward reducing chip technology dependence on the West.
ASML Chief Executive Christophe Fouquet said in April that China was many years away from developing EUV technology at this level. The Reuters report has cast doubt on that timeline. Sources cite roughly 2030 as the realistic horizon for widespread commercial Chinese EUV use, a date considered early in the context of the U.S.-China semiconductor race.
Rapid artificial intelligence growth in China is amplifying domestic demand for advanced manufacturing. Huawei is partnering with SMIC to expand fab networks; SMIC's N+3 process, developed under existing restrictions, is pitched as a 5 nm-class competitor. From a supply chain perspective the picture is clear: the center of gravity for advanced semiconductor capacity is being redrawn.
Key Takeaways:
1. China has produced a working domestic prototype of the EUV lithography tool previously monopolized by ASML.
2. The prototype can generate the ultraviolet light needed to process wafers but still depends on legacy ASML components.
3. ASML CEO Fouquet had previously said China was many years away from this level of EUV capability.
4. Widespread commercial Chinese EUV use is now estimated around 2030, considered early by competitors.
5. Huawei and SMIC are accelerating domestic advanced semiconductor capacity through their partnership.
