May 15 (Reuters) - Firefighters in Phoenix, Arizona,

responded to a reported explosion on Wednesday afternoon at the

Taiwan Semiconductor Manufacturing Company ( TSM ) plant in

the city, the Arizona Republic reported, citing the local fire

department.

In May 2020, TSMC said it would invest $12 billion in

Phoenix to build an advanced semiconductor manufacturing

fabrication. In December 2022, the company announced plans to

build a second fab in the region, increasing its total

investment to $40 billion.

The Phoenix fire department didn't immediately respond to a

Reuters request for comment.
