A state-owned enterprise in Shanghai has reportedly started producing domestically developed immersion deep ultraviolet (DUV) lithography machines, a critical piece of chip-making equipment. While the quality is likely far behind market leader ASML, this development marks a potential breakthrough for China in circumventing US-led semiconductor technology export controls.
This Wire brief sits within Fusion42's coverage of Semiconductors, and 22 sources have reported it between 27 Jul 2026 and 6 Aug 2026.
◆ ◆ The Wire takeaway
The West's monopoly on advanced chip-making tools is ending. A parallel, sanction-proof manufacturing base in China creates a new option if you're designing chips for that market, and a new customer if you build components for lithography.
