TSMC Abandons U.S. Chip Site After Local Protests
Apple foundry partner TSMC has abandoned plans for a new U.S. chip manufacturing site following local community protests. The decision highlights significant headwinds for domestic semiconductor expansion, including local opposition over environmental and infrastructure concerns, potentially constraining the near-term supply of U.S.-made advanced silicon.
The now-canceled project is part of a broader trend of "Not In My Back Yard" (NIMBY) resistance to semiconductor plants. Similar community pushback has occurred in Arizona and Indiana over concerns about water usage, traffic, and the environmental impact of industrial development near residential areas. This local resistance highlights a significant challenge for the CHIPS Act's goal of expanding domestic manufacturing. Chip fabrication plants are incredibly resource-intensive, which fuels local opposition. A single facility can use millions of gallons of water per day and consume more electricity than some countries. The manufacturing process also involves hazardous materials and "forever chemicals" (PFAS), leading to fears of environmental contamination and public health risks. This isn't just a U.S. issue for TSMC; the company abandoned a planned 2nm fab site in Longtan, Taiwan, after local residents protested the land acquisition required for the plant's expansion. The proposed factory was located near a high school and green space, sparking community opposition. TSMC's existing U.S. project in Arizona, a $65 billion investment, is already facing significant headwinds. The project has been plagued by delays, labor shortages, and complex regulatory hurdles that have slowed progress and increased costs compared to building in Taiwan. The operational costs in the U.S. are proving to be a major challenge, with TSMC's margins on U.S.-made chips shrinking significantly due to higher labor costs and other expenses. CEO C.C. Wei noted that the Arizona project has taken twice as long as similar facilities in Taiwan, partly due to navigating multiple layers of municipal, county, state, and federal regulations. For Apple, this trend of local opposition and the high cost of U.S. manufacturing creates uncertainty for the domestic supply chain of advanced silicon. While the CHIPS Act provides subsidies, the structural challenges of building and operating fabs in the U.S. could constrain the supply of domestically produced, cutting-edge chips for future products.
