TSMC plans to more than triple its Arizona investment to $40B, building a fab for 3nm chips, set to open in 2026, and making 4nm chips in its fab for 5nm chips
TSMC more than triples its Arizona commitment to $40B, adding a 3nm fab targeted for 2026 while upgrading the original fab’s planned output from 5nm to 4nm.
Apple, AMD, and the other customers that pressed for 4nm output gain a clearer path to more advanced Arizona-made capacity than the original 5nm plan offered.
Second-order effects
The Biden administration can point to a second TSMC plant as tangible support for its domestic-chip manufacturing agenda, tying the company’s investment more closely to US industrial policy.
TSMC’s Arizona roadmap raises the bar for US-based chip capacity from a single leading-edge plant to a multi-fab program, making future public support and supplier planning more consequential.
Third-order effects
The subsequent US grants and loans for a third Arizona fab and its planned 2nm production show how an initial capacity commitment can become a staged, public-private expansion of leading-edge manufacturing.
If this sequence persists, advanced-node production will be organized around long-term customer demand, large capital commitments, and government incentives rather than one-off fab projects.
The trend: TSMC’s Arizona expansion is part of a broader shift toward building clustered, policy-backed leading-edge chip capacity in the US over multiple technology generations.
TSMC will invest US$40 billion on 2 fabs at its Arizona, USA fab site, with the 2nd fab to begin mass production on 3nm process technology in 2026, TSMC said. The 2 fabs will directly employ 4,500 workers and produce chips on over 600,000 wafers/year. $TSM https://pr.tsmc.com/...
“At scale, these two [factories] could meet the entire U.S. demand for U.S. chips when they're completed,” Chatterji said. “That's the definition of supply chain resilience. We won't have to rely on anyone else to make the chips we need.” https://www.cnbc.com/...
TSMC confirms it has started construction on a 2nd fab in Arizona. 2nd fab will begin production of 3nm chips in 2026. TSMC: US$40bn investment represents the “largest FDI in Arizona history and one of the largest foreign direct investments in the history of the United States.” h…
The US is home to just 13% of the world's semiconductor manufacturing capacity, & we make nothing close to the cutting edge. In fact, the vast majority of the world's most advanced chips are made in Taiwan. However, w/ new investments in AZ from TSMC, that's set to change! https:…
Customer demand, subsidies from states & the $50B+ incentives laid out in the CHIPS & Sci. Act are drawing TSMC, Samsung, & other chip-makers to invest in the US. Encouraging domestic production is a critical step in securing our semiconductor supply chains & national security. h…
“Industry experts said the larger TSMC presence would still be unable to accommodate cutting-edge products such as new iPhone models when the fabs finally open. They added the investments could provide only minimal supply chain security...” https://twitter.com/...

Compared to Asia: The US labor situation is bad (not just more costly, but the desire and skills needed to work are lacking). Building is slower and more expensive. https://www.wsj.com/...
The $12 billion Arizona semiconductor plant under construction that President Biden is visiting Tuesday represents U.S. hopes for a renaissance in manufacturing, but the Taiwanese company building it says it won't be easy. @yoyominnie @KeithZhai https://www.wsj.com/...
