Patent ID: 7057212

Claim:
A nitride semiconductor light emitting diodes, comprising: a transparent substrate for single crystal growth of a nitride semiconductor material; an n-doped nitride semiconductor layer formed on the transparent substrate; an active layer formed on the n-doped nitride semiconductor layer; a p-doped nitride semiconductor layer formed on the active layer; a high reflectivity Ohmic contact layer of a mesh structure formed on the p-doped nitride semiconductor layer and having a number of open areas for exposing the p-doped nitride semiconductor layer, wherein the high reflectivity Ohmic contact layer comprises at least one layer made of a material selected from the group consisting of Ag, Rh, Pd, Ir, Pt, Au and combinations thereof; a metal barrier layer formed on at least a top region of the high reflectivity Ohmic contact layer, wherein the metal barrier layer comprises at least one layer made of a material selected from the group consisting of Ni, Cu, Cr, Ti and combinations thereof; a p-bonding electrode formed on the metal barrier layer; and an n-electrode formed on the n-doped nitride semiconductor layer.
