Patent ID: 7728340

Claim:
A light-emitting diode, comprising: a substrate; a light-emitting part formed on a front side of the substrate, the light-emitting part comprising a first conductivity type cladding layer, an active layer, and a second conductivity type cladding layer stacked sequentially; a first current-blocking portion partially formed on a middle portion of the light-emitting part; a current-conducting portion formed on the second conductivity type cladding layer and the first current-blocking portion; a lower electrode formed on a back side of the substrate; a light-reflecting layer formed between the substrate and the light-emitting part, the light-reflecting layer comprising a metal; a bonding layer formed between the substrate and the light-reflecting layer, the bonding layer comprising a metal; a partial electrode formed on a surface of the light-reflecting layer and in a portion positioned below the first current-blocking portion, the partial electrode comprising a Au-based metal; and a second current-blocking portion formed over the surface of the light-reflecting layer excluding a portion of the light-reflecting layer in which the partial electrode is formed, the second current-blocking portion comprising a silicon-based insulating material, wherein the partial electrode and the second current-blocking portion are provided between the light-emitting part and the light-reflecting layer.
