TYPICAL CHOICES FOR PART ORIENTATION:
Why Sapphire?
Zero Degree: The direction of view is parallel to the optical axis
of the crystal 
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.
