2inch DSP Sapphire Wafer SSP Substrate Single Side Polished Wafer 2inch/4inch/6inch/8inch
Description
The 2inch SSP double side polished sapphire substrates can be manufactured from high quality optical grade Kyropoulos grown sapphire crystals.
high purity single crystal sapphire epitaxial substrate is suitable for direct epitaxial process, PSS process, ALN process and other epitaxial methods. It has the characteristics of uniform wavelength, high brightness and small STD. we can accept product customization for the technical specifications, and produce sapphire single / double polishing substrates with different external dimensions based on C (0001), a (11-20) and m (1100) crystal orientations, with notch or straight edge crystal orientations.
