TSMC's Third Arizona Fab Starts Volume Production on N2 and A16
- TSMC announced a third fab for its Phoenix site in April 2024 alongside up to US$6.6 billion in proposed CHIPS Act funding, saying it would make chips on 2nm or more advanced processes with production beginning by the end of the decade[4].
- Ground was broken on 29 April 2025 near 43rd Avenue and Dove Valley Road during a visit by Commerce Secretary Howard Lutnick[3].
- TSMC's Arizona page now slates the fab for N2 and A16 and still targets volume production by the end of the decade; the first fab has run N4 since Q4 2024, the second targets N3 in the second half of 2027, and a fourth fab and the first advanced-packaging fab began early construction in 2026[1].
- Taiwan's Economic Daily News reported in September 2025 that the fab could be pulled in to 2027 as US customers seek local capacity; TSMC has not confirmed an earlier date[2].
- With the July 2026 pledge of further 2nm-and-below fabs, TSMC puts its Arizona commitment at US$265 billion, the largest foreign direct investment in a US greenfield project, with the first three fabs bringing about 6,000 direct jobs[1].
