Global semiconductor foundry giant TSMC has started producing 4nm chips at its Arizona plant, marking an important milestone for the Biden administration's semiconductor plan.
US Commerce Secretary Raimondo said in an interview published by foreign media on the 11th: "This is the first time in our nation's history that leading 4nm chips equivalent in yield and quality to those in Taiwan are produced on US soil by American workers."
Raimondo stated that the production of 4nm chips began in recent weeks, "This is a major breakthrough—unprecedented in our history, and many people once thought it was impossible to achieve."
TSMC currently has two wafer fabs in Arizona and agreed last year in April to increase its investment from $25 billion to $65 billion, and plans to build a third fab in Arizona by 2030.
TSMC previously expected that the first Arizona plant could start mass production in the first half of 2025, and the second fab will produce the most advanced 2nm chips in 2028. TSMC also agreed to adopt the most advanced chip manufacturing technology "A16" at the Arizona plant.
Raimondo said: "These did not happen naturally... we had to work hard to persuade TSMC to expand its investment."
She expressed hope that by 2030, the US could produce 20% of the world's leading logic chips. Before TSMC began production in Arizona, this percentage was 0%.
