Why Sapphire?

  • Zero Degree: The direction of view is parallel to the optical axis of the crystal Dsp SSP M - Axis Sapphire Windows , Sapphire Wafer 10-10 10-12 2 Inch 0

  • 90 Degree: The direction of view is perpendicular to the optical axis of the crystal

  • C-Axis: In a rod, the direction along its length. In a window, the direction perpendicular to the face.

  • M-Plane: The plane containing the optic axis (C) and inclined 30 degrees to the A-axis

  • A-Plane: The plane that is perpendicular to the A-axis, containing the C-axis

  • R-Plane: A plane inclined 57.5667 degrees to the optic axis in the same zone as the M-plane.

  • Random: There is no specified relationship between the part and the crystalline orientation. The part is manufactured without concern about orientation.

        Sapphire is a hexagonal lattice structure, and many properties are determined by its crystal orientation. Through epitaxial crystal growth, different crystal orientations will exhibit different lattices to match the target material.
Sapphire has certain birefringence characteristics, and special crystal axes are used in some optical fields, such as polarized substrates: C-cut sapphire substrates are used to grow III-V and II-VI deposited films, such as gallium nitride. It can produce blue LED products, laser diodes and infrared detector applications.
Type A substrates produce a uniform permittivity/medium, and high levels of insulation are used in hybrid microelectronics. The high temperature superconductor can be produced by a type A substrate crystal.
Different deposited silicon outer extension crystals of R-type substrate growth are applied to microelectronic integrated circuits. Sapphire is a choice of hybrid substrates due to its high permittivity characteristics, such as in microwave integrated circuits. In addition, high-speed integrated circuits and pressure sensors can be formed during film formation for epitaxial silicon growth. R-type substrate growth can also be applied in the fabrication of tantalum, other superconducting components, high resistance resistors, gallium arsenide.
Both M, A, and R types can grow non-polar or semi-polar gallium nitride. Sapphire as a commercial product still requires a lot of research to improve the material quality of gallium nitride epitaxial.
