Where is TSMC headquartered?

TSMC's global headquarters occupies multiple buildings within Hsinchu Science Park in Hsinchu City, northwestern Taiwan. The campus includes Fab 12A, TSMC's primary R&D centers, and executive offices. Hsinchu Science Park was purpose-built by the Taiwan government in 1980 to concentrate semiconductor and electronics companies, and TSMC has been there since its founding in February 1987.

The official HQ mailing address is: 8 Li-Hsin Rd. 6, Hsinchu Science Park, Hsinchu 300-096, Taiwan, R.O.C. The investor relations phone is +886-3-568-2080 and the IR email is invest@tsmc.com. The Hsinchu campus is also home to TSMC's new fab construction: Fab 20 (2nm N2 HVM since Q4 2025) sits near the global R&D center, and Fab 20 Phase 2 is ramping alongside Fab 22 in Kaohsiung.

Taiwan remains TSMC's manufacturing heartland with fabs in Hsinchu, Taichung (Fab 15), and Tainan Science Park (Fabs 14 and 18 — home to N3/N2 production) — together representing the world's highest concentration of leading-edge semiconductor capacity. The Tainan fabs account for a substantial portion of N3 wafer output serving NVIDIA's Blackwell GPU and Apple's A-series chips.

Outside Taiwan, the most strategically significant site is Fab 21 in Phoenix, Arizona. Phase 1 (4nm) entered high-volume production in Q4 2024 and posted its first annual profit in 2025. Phase 2 construction was completed in April 2026, with equipment move-in scheduled for Q3 2026 and 3nm high-volume manufacturing targeted for H2 2027. In Japan, the JASM joint venture in Kumamoto (with Sony and Denso) achieved its first quarterly profit in Q1 2026 on 12/16nm production. In Germany, the ESMC joint venture in Dresden (with Infineon, NXP, and Bosch, each holding 10%) is in structural build-out, with equipment move-in expected in H2 2026 and volume production of 12/16/28nm automotive chips targeted for 2027–2028. TSMC also opened its first European Design Center in Munich in June 2026.

For field sales and ABM, TSMC's primary buying authority remains concentrated in Taiwan (Hsinchu), but the Arizona expansion has created a fast-growing U.S. procurement center. Phoenix / Chandler is now a major decision-making hub for vendor contracts across facilities, engineering tools, HR platforms, and professional services — operating in Mountain Time and accessible to West Coast-headquartered vendors. The Arizona fab posted a US$514M profit in Q1 2026 alone, signaling it is transitioning from a construction project to an operating business with real procurement budgets.

Europe-focused sellers should prioritize Dresden (ESMC, equipment move-in 2H 2026, first silicon expected 2027) and the newly opened Munich Design Center — the latter signals TSMC's intent to deepen European customer engagement beyond the fab level. Key automotive semiconductor customers (Infineon, NXP, Bosch) are ESMC co-investors and already in TSMC's supply chain. Japan territory (Kumamoto / Tokyo) is served by Makoto Onodera's regional team; JASM's Q1 2026 profitability confirms it is scaling. The Bangalore India office supports fabless customer design teams — relevant for engineering-tooling vendors with Indian sales coverage.
