> Key Milestones:

> First Fab: High-volume production on N4 process technology started in Q4 2024.

> Second Fab: Construction was completed on the fab structure in 2025. Volume production on N3 process technology targeted for 2028.

> Third Fab: In April 2025, TSMC broke ground on the site of the third fab, slated for N2 and A16 process technologies. Targeting volume production by the end of the decade.

> TSMC Arizona will play a crucial role in increasing U.S. production of advanced semiconductor technology and elevate the state of Arizona as an American center of innovation.
