In a significant move, TSMC has chosen Arizona as the site for its latest expansion, signaling a bold step in advancing semiconductor manufacturing within the United States.
The Impact of Political Dynamics on TSMC’s Expansion Plans
Since the onset of the Trump administration, TSMC’s aspirations to establish a presence in the U. S.have reached unprecedented levels. The company is now set to develop advanced chip production capabilities in Arizona to bolster America’s leadership in artificial intelligence (AI).As stated by Peter Cleveland, TSMC’s Vice President, the establishment of a third fabrication plant (fab) in Arizona demonstrates the firm’s commitment to making the U. S.a pivotal location for its operations, thereby underscoring a significant move towards technology transfer.
We have not started to break ground on our third wafer fab in Phoenix. We would like to start next week. We’re going to build those (high-end chips) in Phoenix to sustain the U. S.’s AI leadership.

TSMC is committing an impressive $65 billion to its Arizona facilities, which will include three state-of-the-art chip manufacturing plants. The first fab is set to focus on the production of 4nm chips, with mass production already initiated and companies like AMD having placed orders for their Ryzen CPUs. The subsequent facility is anticipated to manufacture even more advanced chips, such as 3nm and 2nm technologies, including the much-anticipated A16 chip. These advancements will mark a significant leap in chip technology within the U. S.
Previously, we reported on the Taiwanese government’s restrictions preventing TSMC from offshore production of 2nm chips, aimed at preserving Taiwan’s significance in the global semiconductor landscape. However, the evolving dynamics under the Trump administration indicate that TSMC is transitioning its focus beyond Taiwan, with the U. S.emerging as a prime target for future expansions, which has led to pauses on some projects in Europe.

Projected timelines suggest that TSMC’s A16 (1.6nm) chip could debut in the market by the second half of 2026, signaling a two-year delay for U. S.production compared to Taiwan. While this delay is notable, it nonetheless indicates that the U. S.will maintain access to advanced manufacturing nodes, likely enhancing its role in the semiconductor industry over the long term.
According to TSMC’s VP, it is anticipated that the U. S.market will constitute 75% of the company’s operations in the years to come, largely aided by the strategic initiatives of the Trump administration. This shift appears to be re-establishing the U. S.as a crucial player in semiconductor manufacturing, though the full realization of this potential may take several years.
