China begins mass-producing domestic immersion DUV lithography machines, with first units going to SMIC, Hua Hong, and CXMT this year

Summary

China has reportedly begun mass-producing immersion deep-ultraviolet (DUV) lithography machines domestically, according to reporting by The Information cited by Tom's Hardware and confirmed by TrendForce. DUV lithography is the core equipment used to manufacture chips at the 7nm to 28nm nodes that Asml dominates through its Dutch export-controlled tools. The Netherlands restricts DUV exports to China under US-aligned chip controls. The Chinese machines are expected to go first to SMIC, Hua Hong Semiconductor, and CXMT, with five units planned for 2026 and roughly 20 for 2027. The volumes are small relative to global demand, and the machines' precise performance specs were not disclosed; analysts cannot yet assess the yield or throughput gap versus ASML's incumbent tools.

The split

US and Taiwanese coverage treated the report as a significant escalation of China's chip equipment self-sufficiency drive, with concern about its implications for export control effectiveness. The story originated with The Information, a US subscription news outlet, not Chinese official media, which has remained quiet. No Chinese state outlet confirmed the production launch. The gap suggests either the manufacturer's preference for stealth or that the report's sourcing is limited. TrendForce's confirmation from Taiwan adds independent regional credibility.

By the numbers

• ~5, DUV machines expected to be delivered in 2026
• ~20, planned deliveries in 2027
• 3, Chinese chipmakers receiving first units: SMIC, Hua Hong, CXMT
• 0, the number of immersion DUV machines China could domestically produce before this development

Why it matters

DUV lithography is the technology floor for making modern logic and memory chips. If China achieves reliable domestic supply, even at low volumes, it reduces the vulnerability of Chinese chip production to Dutch and US export controls. Asml holds near-total global market share in DUV machines; a credible domestic Chinese alternative, if it achieves competitive yield, changes the strategic calculus of the chip-control regime.

What to watch

• Whether the Dutch or US governments confirm the report and consider tightening controls on DUV-adjacent technology or components
• Whether Asml comments on the competitive threat in its next earnings call
• Whether Chinese state media begins publicising the machines, signalling confidence in their readiness
• Yield and throughput data from SMIC or Hua Hong in their next quarterly disclosures
