Aluminum Nitride EPI Wafers

OMedaSemi can provide customers with high-quality standard sapphire-based aluminum nitride templates in 2/4/6-inch sizes, with aluminum nitride film thicknesses ranging from 200-1000nm. We can also customize non-standard sapphire-based aluminum nitride templates in corresponding sizes and film thicknesses from 50-5000nm. Our products are widely used in UV-LED chips, ultraviolet detectors, and other fields.
