sapphire products is a leading provider of high quality sapphire substrates to the expanding gallium nitride led based market.
Substrate tolerances and surface finish are keys to Gallium Nitride device production and yield.
Sapphire Products sets the standards for flatness and surface finish.
Our strong product development team uses industry standard measurement techniques, such as AFM, X-ray rocking curves and surface analysis to study surface and crystalline quality of substrates.
C-axis  wafers precisely oriented to within ± 0.25° and primary flat tolerances to ± 0.5° are available in 2" diameter.
Other sapphire orientations, misoriented substrates, and wafer tolerances are available.
