SAIC established a compound semiconductor manufacturing platform which combines process technologies for microwave radio frequency, high power electronics, and optical, by having in-house capability and vertical integration of substrate materials, epitaxy growth and wafer fabrication.

In the field of radio frequency millimeter wave, SAIC has launched advanced process technologies for wireless applications such as GaAs HBT, pHEMT and has built a large-scale professional 4-inch and 6-inch compound wafer manufacturing line. In the field of power electronics, SAIC has launched SiC power diodes and silicon-based GaN power devices with high reliability and high power density. In the field of optical communications, SAIC has been capable of producing DFB lasers, photodiodes, avalanche photodiodes and other high-speed optical communication products, and has developed high-power visible and infrared VCSELs, edge-emitting lasers and other products including for 3D sensing, LiDAR and other consumer applications.
