The Wall Street Journal: Taiwan Semiconductor to build $12 billion chip factory in Arizona

TSMC made the decision to go ahead with the project at a board meeting on Tuesday in Taiwan, according to people familiar with the matter, adding that both the State and Commerce Departments are involved in the plans. Construction will begin next year with production targeted for 2024, the company said in a statement.

TSMC’s new plant would make chips branded as having 5-nanometer transistors, the tiniest, fastest and most power-efficient ones manufactured today. TSMC just started rolling out 5-nanometer chips at a factory in Taiwan in recent months. TSMC said the plant would make 20,000 wafers a month, making it a relatively small facility for a company that made more than 12 million wafers last year alone. TSMC’s Fab 18 in Taiwan, which currently produces its 5-nanometer chips, was targeted for 100,000 wafers a month when it broke ground in 2018.
