Product Description
R-plane 1102 C-plane 0001 Sapphire Wafer For IR and UV Wavelength Applications
The growth method refers to the process by which the ingot of single crystal sapphire is produced. For most sapphire wafers this is the Kyropoulos method (abbreviated to Ky or Kr). The Kyropoulos method is a continuation of the Czochralski method (CZ) which is used in the manufacture of silicon wafers. The Kr method allows for the production of very large ingots of single crystal sapphire that can then be processed into wafers.
Typical cuts of sapphire are R-plane (1102), C-Plane (0001), A-plane (1120), M-plane (1010) and N-plane (1123). Orientation affects the physical properties of the sapphire wafers – and in particular how it integrates and lattice matches with other materials.
