Doris Hsu

GlobalWafers makes the silicon wafers that are a crucial component for chipmakers making advanced semiconductors. Leading GlobalWafers is Doris Hsu, who has run the Taiwan-headquartered firm since 2011, when it spun off from Sino-American Silicon Products, another Taiwan-based firm. In 2015, Hsu took GlobalWafers public, and it's now the third-largest wafer manufacturer, supplying the world's top 25 semiconductor firms. Like others in the semiconductor industry, GlobalWafers is banking on the AI and data center boom to lift its revenues this year.
