ASML Shares Hit 7-Week Low as China Reportedly Mass-Produces DUV Tools
3 articles · Updated · Bloomberg · Jul 28
Summary
ASML shares fell to their lowest level since early June after a report said a Chinese state-backed company had begun mass producing immersion deep ultraviolet lithography machines.
The Information said the Shanghai-based manufacturer has assembled development teams from other Chinese companies, including Shanghai Yuliangsheng Technology, to build the DUV tools.
The reported production push threatens ASML’s sales in a key mature-node segment, where immersion DUV systems are widely used and face fewer technical barriers than EUV machines.
The move underscores China’s broader effort to localize semiconductor equipment as export restrictions have limited its access to advanced foreign chipmaking tools.
