Compound-semiconductor lasers and photodetectors are needed for optical links in AI data centers, and DIGITIMES reported WIN is one of the few foundries with production technology for optical communications; but DIGITIMES put optical-related revenue at only about 15-16% of WIN's total, so AI is not yet its main driver.
Charges chip-design companies for manufacturing compound-semiconductor wafers to their designs, plus layout and testing services.
