Tim Cook announced in 2022 that Apple would prioritize using chips produced at TSMC’s new Arizona facility, with President Biden emphasizing the strategic value of local chip manufacturing. Fast forward to today, TSMC’s Fab 21 in Arizona has begun producing 4nm chips, a significant milestone in American semiconductor production. This development was highlighted by Tim Culpan on his Substack, noting that the Arizona plant is making A16 mobile system-on-chips (SoCs), the same chips used in the iPhone 14 Pro and Pro Max and continuing with the iPhone 15 series. While the production volume in Arizona is not as high as TSMC’s facilities in Taiwan, this milestone marks the first advanced-process manufacturing outside of Taiwan for TSMC, a monumental step in global semiconductor diversification.
The Arizona fab has not yet reached the yield rates of TSMC’s Taiwanese facilities, but it is gradually closing the gap, with forecasts predicting near parity by early 2025. This achievement is particularly significant given the U.S. strategic push to enhance domestic semiconductor manufacturing amid ongoing global supply chain disruptions. The shift aims to reduce dependency on concentrated manufacturing hubs in Asia, thus mitigating potential risks associated with geopolitical tensions and localized disruptions. The investment in the Arizona plant reflects a broader consensus on the importance of diversifying semiconductor production locations, and TSMC’s cautious yet optimistic strides herald a new era in U.S. chip production.
Challenges and Future Prospects
Despite the groundbreaking advances at Fab 21, TSMC faces numerous challenges as it continues to expand its footprint in the U.S. The company has two additional fabs currently under construction in Arizona, intended to produce more advanced 3nm and 2nm chips. However, these facilities have encountered delays, with the 3nm facility now projected to begin operations in 2027 and the 2nm fab slated for productivity later in the decade. These delays present logistical challenges and spotlight the complexities involved in establishing state-of-the-art semiconductor manufacturing capabilities outside of TSMC’s home base in Taiwan.
The fruition of these future facilities is crucial not only to meet the growing demand for advanced chips but also to strengthen the U.S. position in the global semiconductor market. Apple’s future utilization of the A16 chip beyond its current deployment in iPhones to potential new versions of the iPad Mini and iPhone SE suggests a continuing and evolving partnership that could drive innovation and market competitiveness. Current models of these devices still operate on the A15 chip, signaling an impending need for the expanded capabilities that these upcoming Arizona fabs are set to provide, despite their delayed timelines.
Strategic Implications and Industry Impact
In 2022, Tim Cook announced that Apple would prioritize using chips manufactured at TSMC’s new Arizona facility. President Biden highlighted the strategic importance of local chip production. Now, TSMC’s Fab 21 in Arizona has begun producing 4nm chips, marking a significant milestone in American semiconductor production. Tim Culpan’s Substack post revealed that this plant is producing A16 mobile SoCs, the same types used in the iPhone 14 Pro and Pro Max, and continuing with the iPhone 15 series.

The Arizona fab hasn’t yet reached the yield rates of TSMC’s Taiwanese operations, but it’s narrowing the gap, with predictions of near parity by early 2025. This achievement is crucial as the U.S. pushes to boost domestic semiconductor manufacturing amid global supply chain issues. This move aims to lessen the dependency on Asian manufacturing hubs, thereby reducing risks related to geopolitical tensions and local disruptions. The investment in the Arizona plant underscores the need to diversify semiconductor production locations, signaling a new chapter in U.S. chip manufacturing.
