Core Technolo gy

Production MOCVD Metal Organic Chemical Vapor Deposition Reactor

Through the organic metal chemical vapor deposition method, the Way to semiconductor film is grown on the substrate, and the epitaxial Produce layer is accurately controlled through the real-time monitoring of the machine to complete the production of epitaxial wafers for 、 different products such as GaAs InP and GaN.

Production Principle

The epitaxial layer is heated by MOCVD in the cavity of the substrate, and an atomic layer is stacked layer by layer to form an epitaxial layer.
