description: "$NVIDIA(NVDA.US)$ASML(ASML.US)$Micron Tech(MU.US)Reports indicate that China has begun mass production of its independently developed deep ultraviolet (DUV) lithography machines, causing US chip stocks to plummet in response. NVIDIA shares fell by over 5%, while ASML and Micron dropped by 7%. SanDisk plunged even further by 12%. Earlier reports suggested that a Chinese state-owned enterprise had started mass-producing independently developed DUV chip manufacturing equipment, sparking concerns about China's push for semiconductor self-sufficiency. The S&P 500 index has now turned negative, erasing early gains, with selling pressure in the semiconductor sector dragging down the broader market."
