Powdec is able to perform face-down crystal growth by our unique MOCVD technology. For this reason, high quality thin films with low defect density are realized. We can grow on sapphire substrate, GaN substrate, and SiC substrate. We can prepare single-layer to multi-layer, or electronic device and optical device structure according to customer's request. We support your R & D or small production.
Substrate size is available from 2 inches to 6 inches Powdec’s unique MOCVD technology

Powdec has succeeded in developing a high-voltage, high-current, high-speed power transistor called a polarization super junction. We will support customers who want to use this power transistor or think about commercialization. We can also manufacture and supply your original design devices. For example, we can manufacture LED wafers for micro displays, so please feel free to contact us.
