TSMC's Arizona Fab 21 began 4nm chip mass production in Q4 2024. Costs are higher than in Taiwan; 2nm production starts in 2025, with 3nm expansion ongoing.

TSMC's new U.S. plant is unlikely to get the most advanced chip technology before factories in Taiwan due to complex compliance issues, local construction regulations and various permitting requirements,

Apple is expanding its US-made chip roster, but according to TSMC’s CEO, the most modern chips will continue being manufactured elsewhere.

TSMC is making a significant push to expand semiconductor production in the United States with a $65 billion investment in Arizona.

U.S. red tape slows TSMC's Arizona plant, as Taiwan remains the priority for cutting-edge semiconductor production

Taiwan Semiconductor Manufacturing Co has begun producing advanced four-nanometer chips for U.S. customers in Arizona, Commerce Secretary Gina Raimondo told Reuters, a milestone in the Biden administration's semiconductor efforts.

TSMCs new Arizona plant faces delays in adopting advanced chip technology, as compliance hurdles, local regulations, and permitting complexities slow progress compared to Taiwan, CEO C.C. Wei said. Building the factory
