TSMC Prepares for Another U.S. Plant as China Tensions Simmer

(Bloomberg) — Taiwan Semiconductor Manufacturing Co. is laying the groundwork for a second U.S. plant next to a $12 billion complex it’s building in Arizona, a major expansion that will boost American efforts to bring advanced chipmaking home if it goes ahead.

The world’s largest contract chipmaker has begun construction on a building that may eventually house its second semiconductor fabrication facility near Phoenix, employing resources already deployed for the current project, the company said in a statement. But it hasn’t made a final decision on whether to proceed with a new plant, TSMC said.
