TSMC starts 4-nanometre chip production in Arizona
Advanced four-nanometre chips are now being produced in Arizona for US customers by TSMC, marking a first for the country.
Taiwan Semiconductor Manufacturing Company (TSMC) has started producing advanced four-nanometre chips in Arizona, marking a significant achievement for US semiconductor manufacturing. Commerce Secretary Gina Raimondo described the development as a historic first for the nation, with production quality matching TSMC’s output in Taiwan.
TSMC’s Phoenix facility received a $6.6 billion government grant to support chip production, alongside up to $5 billion in low-cost loans. The investment is part of a broader initiative to strengthen domestic chip production under a $52.7 billion programme established in 2022.
The company plans further expansion in Arizona, with a second fab producing two-nanometre chips by 2028 and a third fab by 2030. Raimondo aims for the US to produce 20% of the world’s advanced logic chips by the end of the decade.
Amkor Technology was also awarded $407 million to support a $2 billion semiconductor packaging facility in Arizona. Apple will be a major client, with its chips produced nearby at TSMC’s plant.
