China has achieved domestic production of immersion DUV lithography equipment, with a Chinese manufacturer (likely Yuliangsheng, affiliated with Huawei) planning to deliver five units this year to SMIC, Huahong, and CXMT, closing a critical gap in semiconductor self-sufficiency after US export bans in 2023.
This Wire brief sits within Fusion42's coverage of Semiconductors, and 2 sources have reported it between 27 Jul 2026 and 28 Jul 2026.
◆ ◆ The Wire takeaway
Chinese chipmakers have just stopped waiting for Western equipment. DUV production is now domestic, which means SMIC and CXMT can scale 28nm fabs without US approval—and that changes who they need to buy from for packaging, test, chemicals, and secondhand tools.
