Abstract:
1. A light emitting diode comprising: a conductive base substrate; a light emitting structure having a plurality of light emitting layers which generate light in responsive to an injection current; a transparent conductive oxide layer formed on said light emitting structure, said transparent conductive oxide layer having one of an ohmic contact metal grid and a dot patterned layer formed therein and atop said light emitting structure; a metal reflective layer formed on said transparent conductive oxide layer, said transparent conductive oxide layer being formed to prevent said metal reflective layer from reacting with said light emitting layers while annealing for improving ohmic contact of electrodes of said light emitting diode; a diffusion barrier layer formed in between said metal reflective layer and a metal bonding layer; and said metal bonding layer formed in between said conductive base substrate and said diffusion barrier layer so as to bond said conductive base substrate and said light emitting structure.
