TSMC accelerates Arizona expansion, keeps investing in Taiwan

TSMC will speed up its expansion and technology upgrades at its Arizona facilities while continuing to invest in Taiwan, chairman C.C. Wei said at an investor conference.

The company has acquired land near its current Arizona site and aims to introduce its 2 nanometer process, set for commercial production in Taiwan in Q4 2025, to the US.

TSMC is investing US$65 billion in Arizona for three advanced wafer fabs, with the first starting production in 2024.

The company plans an additional US$100 billion investment in Arizona for three more fabs, two IC assembly plants, and an R&D center.

TSMC is working with an outsourced semiconductor assembly and test partner.

Wei did not name the company, but Amkor Technology has announced it is building an IC assembly and testing plant in Arizona.

Wei said TSMC will continue expanding in Taiwan, with new wafer fabs and assembly plants, and no slowdown in local investments.

Implications, context, and why it matters.

Taiwan Semiconductor Manufacturing Co. (TSMC) Arizona plans face open questions on CHIPS Act funding

TSMC Arizona won up to $6.6 billion in CHIPS Act awards for its first three fabrication plants (fabs) 1. State officials announced a $100 billion plan for three more fabs, two packaging sites, and a research and development (R&D) center 2. There is no public confirmation of extra federal money or payout milestones.
The CHIPS Program Office pays out after construction, production, and commercial milestones 1. That setup can constrain schedule changes. As part of its award TSMC Arizona plans to make N3 to N5 Fin Field-Effect Transistor (FinFET) process nodes plus N2 and A16 nanosheet nodes in the United States, so a 2-nanometer (2nm) process in Arizona fits within the current scope 1.

Arizona chip buildout opens near-term work for equipment and service firms

Arizona is building an advanced cluster with chip stacking and high-density interconnect, with more than 60 expansions since 2020 worth over $205 billion in capital investment 2. Vendors can chase work across this network.
TSMC will support advanced packaging with U.S. partners, including Amkor Technology (a U.S.-based outsourced chip packaging plus testing provider) that plans an Arizona packaging plus testing plant and KoMiCo (a semiconductor equipment parts cleaning plus coating firm) that is making a $50 million cleanroom investment in Mesa 1 3 4. Workforce groups can use the Semiconductor Technician Quick Start program with over 900 graduates and align with the state’s $100 million university investment in semiconductor workforce plus infrastructure to help fill about 6,000 direct manufacturing jobs 5 3 1.
