TSMC's Next U.S. Chip Fab May Be Located in Sherman, Texas
nashnova research
TSMC may invest $45 billion in two new wafer fabs in Sherman, Texas — a sign it is spreading its U.S. manufacturing footprint beyond Arizona, driven by major customers demanding more local capacity.
Where does this come from — and is it confirmed?
The *Dallas Business Journal* cited Texas development filings: an unnamed manufacturer plans to invest $45 billion in two semiconductor fabs in Sherman, creating roughly 5,000 jobs over six years with production starting by late 2029.
The filings do not name TSMC, and the site has not been officially confirmed.
But TSMC CEO C.C. Wei told analysts on the latest earnings call that the company has sent a team to Texas to evaluate expansion. This means → the intent is public even without a formal announcement.
Why Sherman and not somewhere else?
Sherman already has semiconductor supply-chain roots. Texas Instruments began volume production at its first 12-inch fab there in December 2025 and plans up to four more, with potential investment reaching $40 billion.
Taiwan's GlobalWafers has also built and started production at a silicon-wafer plant in Sherman. Apple said in February that wafers from the plant would supply its U.S. chip-manufacturing partners, including TSMC and TI.
This means → a TSMC fab in Sherman could source silicon wafers locally, shortening the materials loop — though no formal supply agreement has been announced.
On water supply, Texas filings show a planned 27-mile pipeline from Lake Texoma to the Sherman treatment plant, but the project has no direct link to TSMC's investment.
What does head-to-head competition with Samsung look like?
Samsung already has a presence in Texas: existing capacity in Austin and an advanced fab under construction in Taylor, targeting 2 nm production in 2027, with total central-Texas investment exceeding $37 billion.
If TSMC moves into the same state, the two will compete directly for engineers, construction contractors, and government incentive dollars.
In plain terms = Texas's semiconductor talent pool is already tight; two giants in one state will intensify the scramble for people and subsidies.
How do tax policy and cost pressures factor in?
The federal Advanced Manufacturing Investment Credit covers 35% of qualifying semiconductor capital expenditure, but under current law, projects that break ground after December 31, 2026 will no longer qualify.
This means → without an extension, the Sherman fab could miss the subsidy window, directly denting its investment economics.
TSMC has already warned that overseas fabs will weigh on gross margin by roughly 2 percentage points in 2026, widening to 3–4 points as more U.S. capacity comes online.
What is the core trade-off here?
The push: major U.S. customers are explicitly asking for more local capacity; Arizona alone is not enough.
The pull-back: overseas fabs cost more, compress margins, and face an expiring tax-incentive window.
This reflects TSMC's strategic bind — customer demand and geopolitics keep pushing it forward, but every new overseas fab adds another weight to the income statement. The final site decision is still pending official confirmation.
