Patent ID: 7692205

Claim:
A semiconductor light-emitting device, the device comprising: a substrate; a semiconductor layer stack situated above the substrate, wherein the semiconductor layer stack comprises at least one n-type layer and one p-type layer; an electrode situated above said semiconductor layer stack; an electrode lead wire coupled to said electrode, wherein the electrode lead wire is situated at least partially parallel to the light-emitting surface of the light-emitting device; wherein at least the n-type layer or at least the p-type layer in said semiconductor layer stack comprises a void, wherein the void is situated in a region which the lead wire overhangs when viewed from a normal direction with respect to the light-emitting surface of the light-emitting device, and wherein the area of said void in the semiconductor layer stack is between half and twice the size of the area of the region that would otherwise be blocked by the electrode lead wire in the normal direction.
