Taiwan Semiconductor Manufacturing Company (TSMC), the world’s largest contract chipmaker, is rapidly transforming Arizona into a major global hub for advanced semiconductor production. With construction now underway on its third fabrication plant in north Phoenix, TSMC’s total U.S. investment has surged to an astonishing $165 billion—a sharp increase from the initially announced $12 billion in 2020.

TSMC’s U.S. operations began with plans for a single fab producing 5nm chips. Fast forward to 2025, and the company is now building three advanced fabs—each more sophisticated than the last:

Fab 1 (Operational): Began limited production of 4nm chips in 2024, serving major U.S. tech clients.
Fab 2 (Construction Complete): Will produce 3nm chips and aims to ramp up volume production by late 2026.
Fab 3 (Ground Broken April 2025): Scheduled to manufacture 2nm chips—currently among the world’s most advanced node technologies—by the end of the decade.
