Sapphire semiconductor substrates are manufactured at Sapphire Products from high quality optical grade Czochralski sapphire. Our integrated facilities allow regulation of the production of substrates from crystal growth to fabrication, and to accommodate special requests on very short notice. Sapphire semiconductor substrates are available in all orientations including R-axis (10-12), C-axis (0001), A-axis (11-20), and M-axis (11-10). Substrates are available in various shapes (circular, rectangle, or square), from a few mm up to 100mm in size, and finishes according to customer specification. Primary flats(as per industry standards) are provided on circular substrates for orientation purposes; secondary flats are available on request. Substrate thickness' range from 0.013" (0.25mm) to 0.025" (0.675mm), depending on your particular application requirements.

SECTION BLUE LED SUBSTRATES 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 [0001] 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.
