TSMC responded to the "US $12 billion investment in the new US 3nm plant": the second phase of the Arizona wafer plant has not yet been decided.

CTOnews.com November 9 news, according to Taiwan Economic Daily reported that TSMC said today, so far has not determined the Arizona fab phase II planning. "In view of the strong customer demand for our advanced processes, we will evaluate future plans based on operational efficiency and cost economy factors. "

TSMC said the Arizona fab, currently under construction, contains a portion of the building that could be used for the Phase II plant to improve cost effectiveness by leveraging resources built simultaneously in Phase I. The building allows the company to maintain flexibility for future expansion.

CTOnews.com learned that in May 2020, TSMC announced that it would invest $12 billion in a new fab in Arizona. Construction of the plant commenced in June 2021 and is expected to commence in 2024.

The Wall Street Journal reported earlier today that people familiar with the matter said TSMC plans to announce in the next few months that it will build a cutting-edge semiconductor factory north of Phoenix, Arizona, adjacent to another chip factory announced by the company in 2020.
