Term (Index) Definition
sapphire  single-crystal (hexagonal lattice)Al2O3; can be synthesized and processed into various shapes including wafers; excellent insulater, highly resistant to most common chemicals and temperature, transparent to the wavelengths from about 0.4 tp about 4 micrometers; used as a substrate in SOS (Silicon-on-Sapphire) technology as well as substrate for other thin-film semiconductors such as GaN.
aluminum oxide, alumina, Al2O3  oxide featuring energy gap Eg ~ 5 eV and k ~8; in the form of single-crystal known as sapphire.
Term (Index) Definition
Ultra-Thin Silicon on Sapphire, UTSOS  ultra-thin film of single-crystal Si is formed on sapphire; Silicon-On-Sapphire, or SOS, is a type of a SOI substrate; CMOS based circuitry featuring superior performance in high-frequency (RF) range can be obtained with these substrates providing structure of the Si film is properly engineered (very low defect density).
