Major United States semiconductor companies experienced notable share price drops on Wall Street on Monday following reports of a technological advancement in China's domestic microchip industry. The market movement occurred after the tech media outlet reported on the development. The information reported that a Chinese firm has begun manufacturing domestic deep ultraviolet lithography systems.
The Shanghai-based company, Shanghai Yuliangsheng Technology, is reportedly producing immersion deep ultraviolet machines, which use ultraviolet light focused through liquid to print microscopic electrical circuits onto silicon wafers. Neither Yuliangsheng nor affiliated tech firms Huawei and SiCarrier responded to requests for comment regarding the manufacturing reports.
Developing domestic lithography equipment is considered a major achievement for Beijing as it seeks to reduce reliance on Western technology. Currently, the Dutch firm ASML dominates advanced chip manufacturing equipment and faces strict trade restrictions that limit exports outside the European Union.
If Chinese firms can produce functional lithography machinery at scale, domestic foundries could accelerate processor manufacturing and narrow the technological divide with leading American developers. A domestic supply of advanced processors would also support Chinese artificial intelligence laboratories attempting to match the computing capabilities of top global platforms.
Investor reaction was swift across American markets, impacting several leading technology brands. Shares in Advanced Micro Devices fell by up to eight per cent during trading, while Nvidia dropped nearly five per cent. Memory manufacturer Micron fell by five per cent, and Intel saw its valuation decline by 3.7 per cent.
Industry analysts note that while domestic production represents an important step, building high-yield semiconductor manufacturing lines remains a complex technical challenge that requires years of testing and calibration.
