TSMC manufactures more than 90% of the world’s most advanced logic chips, making it the world leader in semiconductor manufacturing. Back in 2020, it announced the creation of TSMC Arizona and an initial $12 billion commitment to building its first U.S.-located advanced fabrication plant in Phoenix.

As TSMC's Arizona semiconductor fab prepares to begin mass production, the local semiconductor supply chain continues to strengthen. Industry experts suggest that if Trump promotes semiconductor production in the US through measures like increased tariffs,

Advanced manufacturing jobs are growing by the thousands in Arizona. We're working with these employers to ensure high school students can fill them.

Metro Phoenix is becoming a world leader in semiconductor manufacturing and microchip R&D, and that is only reshaping our economy for the better.

Major tech firms may have to remain dependent on Taiwan-based plants, increasing their exposure to geopolitical risks.

TSMC's new U.S. plant is unlikely to get the most advanced chip technology before factories in Taiwan due to complex compliance issues, local construction regulations and various permitting requirements,

But under Trump administration the future of the Act might be jeopardized as he mentioned that Taiwan stealing US chip jobs and suggested alternative strategies to achieve semiconductor independence.

After four years of planning, TSMC is now finally going to make older iPhone processors in the US, but it's not and never will be a true return to American manufacturing.

Taiwan Semiconductor Manufacturing confirmed it started commercial production at its Phoenix complex during fourth quarter when profits surged 57%.

TSMC has been promised $6.6 billion under the Biden-administration’s CHIPS and Science ACT to help build three cutting-edge chip fabrication plants in Arizona.

TSMC's Arizona Fab 21 began 4nm chip mass production in Q4 2024. Costs are higher than in Taiwan; 2nm production starts in 2025, with 3nm expansion ongoing.

In November 2024, the US Commerce Department finalised a $6.6bn grant for TSMC for semiconductor production in Arizona.
