Taiwan Semiconductor Manufacturing Co. broke ground Tuesday on the third factory at its north Phoenix campus, coinciding with a visit from U.S. Secretary of Commerce Howard Lutnick.

TSMC initially planned to break ground on its third fab — which will utilize 2-nanometer and A16 process technologies — later this year, but the company had been in discussions with the U.S. government to help speed up the permit approval process, TSMC CEO C.C. Wei said on an April 17 earnings call.

TSMC obtained approval for an air permit, paving the way to begin construction of its third fab, a company spokesperson told the Business Journal.

In addition, TSMC gained approval earlier this month for reviews related to water, sewer and grading plans for its third fab site, according to city of Phoenix records.
