Single Crystal Sapphire Substrates


C-plane sapphire substrates are used to grow III-V and II-VI compounds such as GaN for blue LED and laser sapphire substratesdiodes. In addition, it is useful for infrared detector applications.

A-plane sapphire substrates provide a uniform dielectric constant and high insulation for hybrid microelectronic applications. High Tc superconductors can be grown with a-plane Sapphire substrates.

R-plane sapphire substrates are used for the hetero-epitaxial deposition of silicon for microelectronic IC applications. Sapphire is an excellent choice for hybrid substrates such as microwave IC's because of its high dielectric constant. In addition, when filmed with an epitaxial silicon process, high speed IC and pressure transducers can be created. Growing thallium, other superconducting components, high impedance resistors, and GaAs are other applications.
