  • Publication number: 20240258463
    Abstract: The present application provides an LED epitaxial wafer and a fabrication process thereof, wherein an N-type GaN layer of the LED epitaxial wafer comprises an N_SL layer and an N_Bulk layer. N_SL layer and N_Bulk layer are equivalent to form multiple capacitive structures, and different silicon doping concentrations enhance the current diffusion and enhance the antistatic capability of LED epitaxial wafer. The arrangement of N_SL layer and N_Bulk layer structure reduces the dislocation density of quantum well light-emitting layer and improves the lattice quality of quantum well light-emitting layer. In the manufacturing process of the LED epitaxial wafer provided by the present application, the SiH4 valve unit of the MOCVD device does not need a higher switching frequency, thereby improving the service life of the SiH4 valve unit.
