Patent ID: 8441019

Claim:
A light emitting device comprising: a substrate; a light emitting structure including a first conductive semiconductor layer, an active layer and a second conductive semiconductor layer, which are formed over the substrate; schottky contact regions coupled to or disposed in the second conductive semiconductor layer; a second electrode over the second conductive semiconductor layer; and a first electrode over an area of the first conductive semiconductor layer, wherein the second conductive semiconductor layer does not overlap the area of the first conductive semiconductor layer over which the first electrode is located, wherein: the schottky contact regions include a first pair of adjacent schottky contact regions and a second pair of adjacent schottky contact regions, the first pair of adjacent schottky contact regions is farther away from a mesa edge region than the second pair of adjacent schottky contact regions, the mesa edge region is located between the first and second electrodes, and a first distance between the first pair of adjacent schottky contact regions is greater than a second distance between the second pair of adjacent schottky contact regions.
