China has started production of home-grown immersion deep-ultraviolet (DUV) chipmaking tools, according to multiple reports citing a source. The equipment focuses on immersion DUV lithography machines, which are used to pattern advanced semiconductor features. One outlet identifies a relatively less-known Chinese state-owned firm, Aishengna, as a lead company in the effort, working alongside top startup teams. The reports describe the move as a step in Beijing’s broader push to reduce dependence on foreign chipmaking technology, particularly in areas where Western firms have supplied equipment. The Kathmandu Post adds that wider success could give Chinese chipmakers an alternative source of lithography tools, which may matter if restrictions on exports of foreign equipment or limits on servicing continue. Overall, the reporting indicates that the production start is an early milestone, with the practical impact depending on whether the tools can be deployed successfully in chip manufacturing and meet performance and supply expectations. The cited sources do not provide detailed specifications, production volumes, or specific customer commitments.
