Sapphire Epitaxial Wafer Description

Sapphire Epitaxial Wafer EPI WaferAt present, the most common substrate used for the growth of GaN is silicon on a sapphire substrate. The advantage of SOS is that its excellent electrical insulation can effectively prevent radiation caused by scattered current from spreading to nearby components. It also features good chemical stability, no visible light absorption, moderate price, and relatively mature manufacturing technology.

The essence of (SOS) is a heteroepitaxial process, that is, a thin layer of SI (typically less than 0.6 microns) is grown on a sapphire wafer. SOS belongs to the silicon epitaxial technology on an insulator substrate in CMOS technology (SOI) Because of its inherent radiation resistance, SOS is mainly used in aerospace and military applications.
