TSMC is considering building a second major semiconductor manufacturing campus in the United States, and notably, neither of the two options under review is in Europe. The company's massive complex in Arizona is already taking shape, with the first fab operational and more advanced nodes on the way. This decision underscores a strategic pivot toward the US, driven by demand for AI chips and geopolitical caution.
TSMC's Arizona Campus: A Titanium-Scale Project
The complex of factories that TSMC is building in Arizona is titanic. Its first semiconductor production plant at this campus began operation two years ago, though it did not reach large-scale manufacturing on the N4 (4 nm) node until last year. This is only the first link in the chain. The second plant will be operational in 2028 and will manufacture integrated circuits on the N3 (3 nm) and N2 (2 nm) nodes.
Finally, the third factory will not be fully ready until the end of this decade and will produce chips on the N2 (2 nm) node or even an more advanced node. These facilities are crucial for the US to reduce its dependence on chips from Asia, so it is reasonable to expect that the problems hampering the construction of these fabs will eventually be resolved.
Why the US Needs This Campus
This project is not only important for the US; it is also crucial for TSMC. Its Phoenix campus will enable the company to respond more effectively to the enormous demand for integrated circuits for artificial intelligence (AI) applications in the medium term. Moreover, strengthening its infrastructure outside Taiwan is a precautionary measure against a possible future conflict with China.
This scenario, in fact, has prompted TSMC to consider building a second major chip manufacturing hub in the US. The state of Texas and another location are reportedly in the running, but Europe is not among the options. This raises questions about Europe's role in the global semiconductor supply chain.
The Two US Options and Europe's Absence
TSMC is reportedly weighing two locations for its second US campus, though the specific sites have not been officially confirmed. What is clear is that neither option is in Europe. This omission is striking given Europe's ambitions to boost its own chip production through initiatives like the European Chips Act.
Europe has been trying to attract major semiconductor manufacturers, but TSMC's focus on the US suggests that incentives and strategic considerations are tipping the scales. The US offers a combination of federal funding, a large market, and a desire to onshore critical technology.
Key Takeaways for the Semiconductor Industry
- TSMC's Arizona campus is a multi-fab project with advanced nodes (N4, N3, N2) coming online through 2028 and beyond.
- AI demand is a major driver for TSMC's expansion, as the company needs to meet growing demand for AI chips.
- Geopolitical risk is pushing TSMC to diversify production outside Taiwan, with the US as the primary beneficiary.
- Europe is not in the running for TSMC's second major US campus, highlighting challenges in attracting leading-edge chip manufacturing.
- Construction challenges in Arizona are expected to be resolved, given the strategic importance of the project.
Comparing TSMC's Global Expansion
TSMC's global footprint is expanding, but the US is clearly a priority. The table below summarizes key aspects of TSMC's major overseas projects.

| Location | Status | Nodes | Timeline |
|---|---|---|---|
| Arizona, US (first fab) | Operational | N4 (4 nm) | Began operation 2 years ago; large-scale last year |
| Arizona, US (second fab) | Under construction | N3 (3 nm), N2 (2 nm) | Operational in 2028 |
| Arizona, US (third fab) | Planned | N2 (2 nm) or more advanced | End of decade |
| Second US campus | Under consideration | TBD | TBD |
| Europe | Not under consideration for second campus | N/A | N/A |
What This Means for Europe's Chip Ambitions
Europe's absence from TSMC's second campus options is a setback for the region's goal of increasing its share of global chip production. The European Chips Act aims to double Europe's market share to 20% by 2030, but attracting top-tier manufacturers like TSMC is essential.

Without TSMC, Europe may need to rely on other players like Intel, which has announced plans for fabs in Germany, or focus on mature nodes and specialty chips. However, the most advanced chips for AI and high-performance computing will likely continue to be manufactured in the US and Asia.

FAQ
Why is TSMC not considering Europe for its second campus?
TSMC's decision to focus on the US for its second campus is likely driven by a combination of factors, including federal incentives, a large customer base, and strategic alignment with US national security interests. Europe, despite its Chips Act, may not offer the same level of subsidies or market demand.
What nodes will the Arizona fabs produce?
The first fab produces N4 (4 nm) chips, the second will produce N3 (3 nm) and N2 (2 nm) chips, and the third will produce N2 (2 nm) or more advanced chips. These are among TSMC's most advanced nodes.
How will this affect the global chip supply chain?
TSMC's US expansion will reduce the world's reliance on Taiwan for advanced chips, which is important given geopolitical tensions. It will also boost the US's domestic chip production, potentially shifting the balance of semiconductor manufacturing.
What challenges is TSMC facing in Arizona?
TSMC has faced construction delays and labor issues in Arizona, but these are expected to be resolved given the project's strategic importance. The company is committed to making the campus a success.
