Gaas wafer process
Webmechanical strength of the wafers. CMP The basic CMP process is the same for GaAs as it is for Si based IC’s. The silicon process involves removing dielectric material using both chemical action and physical abrasion. Placing a wafer coated with a dielectric film in contact with an abrasive pad polishes the wafer’s surface. The pad is coated WebGaAs/AlGaAs-based pHEMT growth process, the platens are coated with mixture of GaAs and AlGaAs layers. AlGaAs material accumulated on the growth platens tends to adsorb oxygen when exposed to the atmosphere during the wafer unloading process, and the more the platens are used, the more oxygen will be accumulated on the platens.
