Arizona Expansion — Second Phase

See all projects by TSMC →

TSMC announced an additional $100 billion U.S. investment in March 2025, building on the ongoing $65 billion Phoenix three-fab campus. The second phase includes three new fabrication plants, two advanced packaging facilities and a major R&D center. The announcement cites 40,000 construction jobs and tens of thousands of high-paying manufacturing and R&D jobs across the expanded effort, but it does not publish a phase-specific newly announced permanent operating-job count. The existing 6,000 direct-job commitment belongs to the original three-fab phase and is deliberately not duplicated here; the announcement did not disclose a separate new permanent operating-job figure for this phase. TSMC published the $100 billion as a single unsplit package covering all six of these components — three fabrication plants, two advanced-packaging facilities and one R&D center — and did not disclose a per-facility capital breakdown, so the figure is not purely fab capital expenditure and includes a non-manufacturing research-and-development component that cannot be separated out.

Why this project qualifies

With $100 billion in facility-specific investment, this project clears AFT's $100 million investment threshold (AFT includes any project meeting $100 million in facility-specific investment OR 100 permanent operating jobs). This project also meets AFT's primary-source verification and physical U.S. manufacturing-footprint requirements.

Why it matters

The semiconductors context.

Semiconductor fabrication plants, known as fabs, rank among the most capital-intensive industrial facilities ever built—often requiring $10–$30 billion and several years from groundbreaking to initial production. The CHIPS and Science Act of 2022 accelerated a U.S. construction cycle spanning advanced chip fabrication, legacy-node production, semiconductor equipment, packaging, and critical materials. These projects create long-term manufacturing footprints while attracting suppliers, infrastructure investment, and specialized technical work.
