WIN Semiconductors Corp. was founded in October of 1999, and has become the first pure-play 6-inch GaAs foundry in the world. In recognition of the growing demand, three advanced GaAs wafer fabs were established to manufacture cost-effective, high speed, and high quality GaAs MMIC's (monolithic microwave ICs) and RFIC's (radio frequency ICs).

WIN provides dedicated foundry services to design houses and integrated device manufacturers. Using state of the art GaAs technology, WIN supplies HBT and pHEMT MMIC fabrication services to worldwide IC corporations. With MMIC technique as basis, WIN also provides optoelectronic device fabrication services for optical communication and 3D sensing applications.
