China Begins Limited Production of Domestic Immersion DUV Machines

Posted on
China has reportedly begun limited production of domestic immersion DUV lithography machines as it works to reduce dependence on ASML equipment.

Quick Report

China has reportedly started limited production of domestically developed immersion deep ultraviolet lithography machines. The equipment is intended to give local chipmakers another source of tools after export controls restricted access to advanced foreign manufacturing systems.

The first systems are expected to target mature process technology, with further testing and production scaling still required. The development does not immediately erase ASML's advantage, but it could strengthen China's semiconductor equipment supply chain over time.
