Chinese Startup Unveils EUV Prototype Amid Doubts Over Commercial Viability
Chinese startup Langdao Silex unveiled a prototype extreme ultraviolet (EUV) light source claiming 90 percent domestic components and promising commercialization within three to five years. Experts, however, doubt China can develop a viable EUV lithography machine for commercial chipmaking within the next decade, citing significant technical challenges. Analysts suggest the announcement serves as geopolitical signaling to pressure the US and allies to ease export restrictions, while also aiming to attract funding and demonstrate progress on state-backed projects despite the prototype's current performance falling short of commercial standards.
