Taiwan’s GlobalWafers Prepares Phase Two Expansion at Texas Plant

Taiwanese silicon wafer maker GlobalWafers is preparing for a second-phase expansion of its Texas manufacturing plant, pending customer commitments, chairperson Doris Hsu said on Wednesday.

The company opened a $3.5 billion facility in Texas last year and later announced plans to invest an additional $4 billion in the United States to meet rising demand. The site is GlobalWafers’ most advanced fully integrated 300mm silicon wafer plant and is currently the only advanced wafer manufacturing facility of its kind in the U.S.

Hsu said customers have begun asking about further capacity increases, noting that the first phase serves multiple clients and may not be sufficient. GlobalWafers is moving ahead with factory design work to shorten timelines once commitments are finalized.

GlobalWafers supplies TSMC, which is investing heavily in U.S. chip production. The expansion aligns with a recent U.S.-Taiwan trade deal aimed at strengthening local semiconductor supply chains.
