Taiwan computer chipmaker TSMC pledges another $100 billion to expand US chipmaking capacity

TSMC, the world's largest contract chipmaker, announced an additional $100 billion investment in U.S. chip manufacturing, raising its total U.S. pledges to $265 billion. The expansion, driven by strong AI-related demand, includes four new Arizona fabrication plants for advanced 2-nanometer chips, supported by a U.S.-Taiwan trade agreement that reduced tariffs on Taiwanese goods.
