Water shortages and local labor gaps threaten Arizona Fab, TSMC says
- Taiwan’s NDC chief Yeh Chun-hsien said on May 11 that TSMC’s Arizona chip campus is ahead of expectations, but water and labor shortages remain real constraints. - The site earned NT$16.14 billion in 2025, its first full year of mass production, even as TSMC still flagged visas, utilities and regulation. - That matters because TSMC now wants a US$165 billion U.S. footprint, and Arizona frictions show reshoring chips is slower than slogans.
Semiconductor manufacturing is the most capital-heavy version of “just build it here.” You need clean rooms, power, water, permits, suppliers, and a trained workforce that already knows how fabs run. That is why the Arizona project matters so much. It is the flagship test of whether the U.S. can rebuild leading-edge chip production at scale. On Monday, Taiwan’s National Development Council chief Yeh Chun-hsien said TSMC’s Arizona site is doing better than expected — but he also said the company is still running into water shortages, labor gaps, visa issues, and utility constraints. ### What happened today? Yeh made the comments after visiting TSMC’s Arizona hub and attending the SelectUSA Investment Summit in Maryland last week. His update was notable because it mixed good news with a very blunt reality check. The first Arizona fab is already in mass production and profitable, but the next phase of scaling is running into the boring, physical bottlenecks that actually decide whether a fab cluster works.

TSMC’s second Arizona fab has finished construction and is scheduled to begin mass production in the second half of 2027. A third fab started construction earlier in 2026. Those three plants were the core of the earlier US$65 billion Arizona buildout. ### Why is the profit number a big deal? Because it shows this is no longer a symbolic factory. (focustaiwan.tw) Yeh said the Arizona site made NT$16.14 billion — about US$514 million — in 2025, its first full year of mass production. He also said TSMC was surprised by how smooth the first fab’s trial run went. That matters because the Arizona project spent years being framed mostly as a delay story. Now it has crossed into actual output and actual earnings. ### Why is water such a hard constraint? Chip fabs burn through huge amounts of ultrapure water. TSMC’s Phoenix site has been building a reclamation system to recycle wastewater, with a goal of reusing 85 percent to 90 percent and pushing toward near-zero liquid discharge. But the scale is still huge: one report on the project said the first fab uses about 4.75 million gallons a day, and the first three fabs together could need 17.2 million gallons a day when fully running. (focustaiwan.tw) In the desert, that is not a side issue — it is core infrastructure. ### Is this just a water problem? No — the labor piece may be even trickier. Yeh said TSMC is still dealing with labor shortages and trouble getting visas for overseas hires. That fits the broader pattern from the Arizona buildout, where the company has needed specialized construction workers, equipment technicians, and experienced fab staff all at once. A fab is not like a warehouse — you cannot just fill seats fast and train later. (datacenterdynamics.com) ### How big is TSMC trying to make this? Much bigger. In March 2025, TSMC said it would add another US$100 billion to its U.S. plans, on top of the existing US$65 billion. The expanded plan includes three more fabs, two advanced packaging facilities, and an R&D center, bringing the total to US$165 billion. TSMC said the site has been in volume production since late 2024 and pitched the expansion as part of a domestic AI supply chain. (focustaiwan.tw) ### So what is the catch for customers? A U.S. fab footprint helps, but it does not magically erase supply-chain fragility. Customers still need qualified processes, reliable utilities, enough trained workers, and local suppliers that can follow TSMC into Arizona. Yeh explicitly said TSMC wants Taiwanese upstream chemical and equipment suppliers to expand there too. Basically, one profitable fab is proof of concept. A full Arizona ecosystem is the harder build. (pr.tsmc.com) ### Bottom line The Arizona campus is now real enough to make money, which is a major milestone. But Monday’s update was a reminder that semiconductor reshoring is constrained by pipes, power lines, visas, and people — not just by headline investment totals. (focustaiwan.tw)
