According to Taiwan media reports, TSMC's Arizona plant will delay mass production from 2024 to 2025。There are divergent views on the reasons for the lagging progress of plant construction in the United States.。According to professional analysts, union resistance in the U.S. is only one of the problems, as well as other reasons such as increased costs and a lack of experience in fab building audits by local government regulators.。Earlier, Yang Yingchao, chairman of Cokland Capital, had said that TSMC's biggest problem was that its employees were not acclimatized, and that TSMC treated Phoenix as a Hsinchu industrial park, but that Phoenix's employees were not on the move, and that the overtime culture made Americans unaccustomed.。
