在美扩厂成本居高不下，台积电美国厂“毛利率缩水近87%”

Group 1 - TSMC's expansion in the U.S. has significantly harmed its profit margins, with gross margins for 5nm chip production in Arizona shrinking by nearly 87% compared to Taiwan due to high labor costs and increased depreciation expenses [1] - The depreciation costs for the Arizona facility are approximately four times higher than those in Taiwan, as the output is only a quarter of that in Taiwan, leading to substantial cost pressures [1] - The high costs have resulted in the largest quarterly profit decline for TSMC's Arizona plant, raising concerns about the sustainability of chip manufacturing outside Taiwan [1] Group 2 - TSMC's efforts to establish a semiconductor hub in Phoenix, Arizona, face numerous challenges, including complex regulations, labor shortages, and high costs, complicating large-scale construction projects in the U.S. [2] - The construction plans are perceived as influenced by political pressures rather than purely commercial interests, with implications for Taiwan's semiconductor industry and its future development [2]
