Xiaomi's breakthrough in creating a 3nm chip without using EUV lithography technology marks a significant moment in the ongoing US-China tech competition. Despite US restrictions on advanced semiconductor technology access, this Chinese tech giant has potentially found a way to manufacture cutting-edge chips, possibly through SMIC. This development could reshape the global semiconductor industry and impact companies worldwide. While details await official confirmation, this achievement might influence US export control policies and accelerate China's progress toward semiconductor independence.
