Why China’s DUV Push Hit ASML (ASML) and Micron (MU) for Different Reasons - Yahoo! Finance Canada

On July 28, 2026, Reuters reported that China had begun producing domestic immersion deep-ultraviolet (DUV) lithography tools. This development impacts ASML and Micron Technology differently. ASML, a ... Read original →

China's domestic immersion deep-ultraviolet (DUV) lithography production, initiated in 2026, introduces a subtle but strategic challenge to ASML’s market dominance, particularly as EUV exports to China remain constrained. While current Chinese DUV systems lag behind ASML in performance, their growing presence could erode long-term demand for ASML’s high-end equipment. For Micron, the rise of CXMT and other local DRAM producers using these tools poses margin pressures, especially if their production efficiency improves. This development signals a broader shift in global semiconductor supply chains, driven by geopolitical tensions and the push for self-reliance. ASML may need to accelerate partnerships in non-sensitive markets, while Micron must brace for intensified domestic competition. Over the next 12–24 months, if China advances DUV capabilities significantly, it could reshape the global photolithography landscape, compelling international vendors to restructure their strategies and geographic footprints.
