TSMC is speeding up expansion in north Phoenix

The TSMC facility in north Phoenix in July 2025.

Taiwan Semiconductor Manufacturing Company announced it is speeding up expansion at its site in Arizona.

The chipmaker says the growth comes from demand for artificial intelligence and high-performance computing chips.

The company says its plans will allow for a third of the production of some of its most advanced chips to be made in Arizona.

TSMC just finished construction on a second fabrication facility and broke ground on a third in April. But according to a quarterly earnings report, that is a fraction of its total plans at its site just off Loop 303 and I-17 in Phoenix.

The so-called "GIGAFAB cluster" will include three more chip facilities, two advanced packaging fabs for artificial intelligence and an R and D Center.

The plans are part of an additional investment of $100 billion in the U.S. that TSMC announced earlier this year.
