Wei did not give a timeline for when the new plants would be built, saying only that it would depend on the “market situation.” The new plants would be added to the eight that are already being built or planned.

“We believe this investment will help further 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,” Wei said.

President Trump wants to boost American production of semiconductor chips, which are found in machines ranging from cars to smartphones, and has been a priority for the United States since shortages during the Covid-19 pandemic exposed supply chain risks.

He previously attributed TSMC’s decision last year to expand its investments in the US to its threats to impose tariffs on Taiwan and the global semiconductor business.

In January this year, the United States said it had agreed to reduce tariffs on products from Taiwan to 15% in exchange for hundreds of billions of dollars in investments aimed at boosting domestic semiconductor production.

Commerce Secretary Howard Lutnick welcomed the plans, saying: “President Trump’s leadership is driving companies to invest in American manufacturing.

“TSMC’s announcement of an additional $100 billion in investment following our historic trade and investment agreement with Taiwan will create tens of thousands of American jobs and bring advanced semiconductor manufacturing back to the United States.”
