CTS: Chinese logic and memory chipmakers have imported 343 ASML immersion DUV lithography scanners from 2012 to early 2026, many of which can make 7nm chips (Anton Shilov/Tom's Hardware)

China’s chipmakers have built a sizable installed base of ASML immersion DUV scanners, giving them meaningful capability to produce advanced chips around the 7nm class even without broad access to EUV. For CIOs and technology leaders, this underscores that semiconductor supply chains are becoming more resilient and strategically important in China, which could affect global capacity, pricing, and geopolitical risk management for hardware sourcing.
