TSMC Stacks its US Pledge to $265 Billion Amidst AI Chip Demand to Build Four New Arizona Plants

The Taiwan Semiconductor Manufacturing Company (TSMC) is planning to invest an additional $100 billion in the US, the firm's management confirmed in its earnings call earlier today. TSMC is the world's largest contract chip manufacturer and had already pledged to invest $165 billion into US chip manufacturing ahead of today's announcement, with $65 announced during the Biden administration and $100 billion in the Trump administration.

Even though TSMC has now committed $265 billion to manufacturing advanced chips in America, all of the firm's leading-edge products are manufactured in Taiwan through the 2-nanometer manufacturing process technology. This technology is primarily used in low-power chips, such as those used in laptops and smartphones. High-power products, such as AI GPUs, are manufactured with older technologies, such as the 4-nanometer manufacturing process.

The Commerce Department confirmed TSMC's announcement in a press release. It outlined that the funds will be used to build four additional chip manufacturing plants in America. The plants will be responsible for manufacturing and packaging the chips. Chip packaging, which is the process through which the final product used in a computer is assembled, emerged as one of the earliest bottlenecks when it came to AI chip production.

TSMC's management also discussed the investment in its latest earnings call. "We believe this investment will help ​to further foster the development of the U.S. semiconductor ecosystem, strengthen the supply chain, and support an increasing number of high-tech, high-paying jobs in the ‌United States," said the firm's CEO, C. C. Wei. The CEO added that the latest chunk of the investment, which will see four new plants being built, would be determined on the "market situation."

The construction of semiconductor production plants is a multi-year process, which is often determined by the demand for the products that they will manufacture. The boom in AI chip demand has changed this reality to some extent, at least for memory manufacturers who are faced with excess demand over capacity.

During TSMC's earnings call, Wei discussed the outlook his firm had received with regard to demand. "Our customers and customers' customers, who are mainly the cloud service providers, continue to provide us with ​their very strong signal and positive outlook," he said. "Thus, our conviction ⁠in the multi-year AI megatrend remains very high," Wei added.
