China's DUV Development Impacts ASML and Micron Differently
China has begun producing domestic immersion deep-ultraviolet (DUV) lithography tools, according to a Reuters report. These systems are intended for use by major Chinese semiconductor firms like Semiconductor Manufacturing International Corporation and Hua Hong Semiconductor. While production is expected to remain limited—around five units in 2026 and about twenty in 2027—the development poses direct competition to ASML (NASDAQ:ASML), which currently dominates the DUV market in China. For Micron Technology, Inc. (NASDAQ:MU), the impact stems from potential supply-side changes rather than immediate product substitution. If Chinese memory producer ChangXin Memory Technologies can leverage domestic DUV tools for reliable commodity-memory production, it could increase industry supply and pressure pricing dynamics that affect Micron's margins. ASML faces a strategic risk as China reduces reliance on its equipment, though current performance metrics of the new systems still lag behind ASML’s. Meanwhile, Micron remains in strong demand with recent financial results showing robust revenue growth.
