TSMC planning advanced chip production in Arizona, says company’s founder

Taiwanese chipmaker TSMC is planning to produce chips with advanced 3-nanometre technology at its new factory in the U.S. state of Arizona but the plans are not completely finalised yet, the company’s founder Morris Chang said on Monday.

TSMC, a major Apple Inc supplier and the world’s largest contract chipmaker, is constructing a $12 billion plant in Arizona. Last year, Reuters reported TSMC’s plans to build more chipmaking factories in Arizona, including discussions about whether its next plant should be more advanced which could make chips with 3-nanometer technology compared to the slower, less-efficient 5-nanometer chips that will be churned out when the facility begins production.
