台积电美国厂暴跌100倍，遭重创！现实打脸!

Core Insights - TSMC's investment in the Arizona factory is seen as a milestone for the U.S. chip industry, but rising costs are significantly eroding profits and putting operational pressure on the company [1][2]. Group 1: Financial Performance - TSMC's profits from its U.S. operations have plummeted over 100 times, dropping from NT$42.32 billion to NT$410 million due to the large-scale semiconductor manufacturing plans [2]. - The profitability of TSMC's second factory in Arizona is expected to decline as the company invests heavily in advanced chip production lines, such as the 3nm process [3]. Group 2: Strategic Importance - The Arizona factory is strategically significant for the U.S. chip industry and aims to help build a supply chain that is less affected by geopolitical conflicts [2]. - TSMC's rapid investment in the U.S. is driven by customer preferences for American manufacturing solutions, a trend that has intensified since the Trump administration [2]. Group 3: Cost Challenges - Manufacturing in the U.S. is inherently high-cost due to elevated labor and construction expenses, along with the need to import talent from Taiwan [3]. - The push for advanced processes like 3nm requires substantial resource investment, leading to lower profitability for TSMC's U.S. operations compared to other regions [3].
