TSMC (Taiwan Semiconductor Manufacturing Company), the world’s largest semiconductor manufacturer, is reportedly planning to increase its investment in Arizona by $12 billion in order to produce 3nm semiconductors in addition to the 5nm semiconductors already planned for its plant currently under construction. This was revealed by the American daily The Wall Street Journal. A second TSMC factory would be set up near Phoenix, close to the one that is currently being built. In this capital-intensive industry, a new semiconductor manufacturing facility can cost between $10 and $20 billion. However, the American government, through the Chips ACT, has decided to subsidise manufacturers who set up new factories on its territory. Logically, this latest project should be able to benefit from American public funds. TSMC is a heavyweight and the main supplier of chips to Apple. In parallel with the United States, the Taiwanese foundry also plans to develop in Japan.
