TSMC Arizona
The Phoenix subsidiary of Taiwan Semiconductor Manufacturing Company, told here only as a factory story: what it takes to move the world's best chipmaking process across the Pacific. The company, AI-demand and export-control angle is in AI: TSMC, and every shared figure here is kept equal to it. TSMC announced a single ~$12bn, 5 nm-class fab in Arizona on 15 May 2020. It raised the plan to two fabs and $40bn at a tool-in ceremony on 6 Dec 2022, slipped the first fab to 2025 in Jul 2023 for lack of skilled installers, and took a $6.6bn CHIPS Act award (final, Nov 2024). Fab 1 then reached volume production on N4 in Q4 2024, with yields reported comparable to Taiwan's. The US plan grew to ~$165bn (3 Mar 2025, equal to AI), the first Nvidia Blackwell wafer came off the Phoenix line in Oct 2025, and the subsidiary swung from a reported ~NT$14.3bn loss in 2024 to a ~NT$16.1bn profit in 2025 (annual report as reported). In Nov 2026 the second fab's building was finished and being equipped for 3 nm volume in 2H 2027 (Shared facts). TSMC Arizona's story turns on process capability: tools can be shipped in weeks, but the people and practice that run them at Taiwan's yields move slowly.
At a glance
- Founded
- Announced 15 May 2020 as a US subsidiary for a fab in Arizona (company; equal to AI's 2020 move). The site, in north Phoenix, is often called Fab 21 (from memory, verify naming)
- Headquarters
- Phoenix, Arizona; parent TSMC in Hsinchu, Taiwan
- Ownership / structure
- Wholly owned subsidiary of TSMC (listed in Taipei, 2330, and on the NYSE as ADRs, TSM — AI KB). Arizona's results appear in the parent's annual report as a subsidiary line
- Leadership (2026)
- Run by a subsidiary president reporting to TSMC headquarters; parent chairman and CEO C.C. Wei led the 2022 and 2025 expansions (AI KB). Current subsidiary president's name not confirmed in C18 searches (verify)
- Plants
- Fab 1 (N4-class) in volume production since Q4 2024; Fab 2 (N3) building complete, tool move-in from Q3 2026, 3 nm volume expected 2H 2027; Fab 3 (N2 and A16 planned) broke ground Apr 2025 (reported), volume "by the end of the decade" (reported); a fourth fab and the first advanced-packaging plant in permitting (reported, 2026)
- Scale
- Fab 1 planned at ~20,000 wafers a month (300 mm) in the 2020 plan (company, equal to AI; current output not disclosed). Subsidiary result: ~NT$14.3bn loss in 2024; ~NT$16.1bn profit in 2025 (~$514m), its first full year of volume production (TSMC annual report via TrendForce and Arizona press, reported). More than 1,000 engineers from Taiwan on three-year assignments (CommonWealth via TrendForce, May 2026, reported)
- Capital and subsidies
- US plan $12bn (2020) → $40bn (Dec 2022) → $65bn (Apr 2024) → ~$165bn (Mar 2025: six fabs, two advanced-packaging plants, an R&D centre — company, equal to AI). CHIPS Act direct funding $6.6bn (final, Nov 2024) plus up to ~$5bn of loans (reported); 48D investment credit (35% for construction begun by 31 Dec 2026 — Shared facts). A ~900-acre second parcel bought at a state land auction on 7 Jan 2026 for ~$197m (reported)
- Signature moves (incl. failures)
- The Phoenix announcement (2020); the tool-in and $40bn plan (2022); the construction-labour shortage, Taiwanese technicians and the union dispute (2023, a setback); the CHIPS award (2024); Fab 1's N4 ramp and yields (2024); the workplace-culture lawsuit (2024–26, a controversy); the $165bn plan and the gigafab cluster (2025–26); the first Blackwell wafer, Fab 2 timing and the packaging gap (2025–26)
