These specifications cover requirements for monocrystalline silicon epitaxial layers on sapphire substrates, used for semiconductor device manufacture. The combination of a silicon epitaxial layer on a sapphire substrate is known as a silicon on sapphire (SOS) epitaxial wafer. By outlining an inspection process and defining various reject criteria, both suppliers and purchasers can uniformly define epitaxial layer quality.
