Patent ID: 7795054

Claim:
A method of manufacturing a vertical structure light emitting diode device, the method comprising: sequentially forming a first conductivity type III-V group compound semiconductor layer, an active layer, and a second conductivity type III-V group compound semiconductor layer on a substrate for growth; forming a reflective metal layer on the second conductivity type III-V group compound semiconductor layer, forming a diffusion barrier metal layer on the reflective metal layer, forming a first metal bonding layer on the diffusion barrier metal layer, preparing a conductive substrate having a second metal bonding layer thereon, bonding the first metal bonding layer and the second metal bonding layer, removing the substrate for growth from the first conductivity type III-V group compound semiconductor layer; and forming an electrode on an exposed portion of the first conductive III-V group compound semiconductor layer due to the removing the substrate for growth, wherein the bonding of the first metal bonding layer and the second metal bonding layer, comprises: partially heating a metal bonding layer by applying microwaves to a bonding interface, and applying a pressure together with the microwaves to the bonding interface while bringing the metal bonding layers into contact with the bonding interface.
