Apple and Nvidia chip supplier TSMC is spending US$65 billion on three giant factories in the state of Arizona.

TSMC's N2 (2nm) process node is "well on track" for volume production in the second half of 2025, as scheduled, Wei said. This is expected to offer a 10 to 15 percent speed improvement at the same power versus N3E technology, or a 20 to 30 percent power improvement at the same speed, and an increase of more than 15 percent in density.

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

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,
