Abstract:
1. A light emitting device comprising: a first semiconductor layer of a first conductivity type, the first semiconductor layer having a recess; an active layer on the first semiconductor layer, the active layer having a first opening; a second semiconductor layer of a second conductivity type adjacent to the active layer, the second semiconductor having a second opening; a semiconductor region of a second conductivity type in the first semiconductor layer; a first electrode on the semiconductor region; a second electrode adjacent to the second semiconductor layer, wherein the first and second openings and the recess are substantially aligned, and the second electrode includes a protrusive portion which extends into the first and second openings and the recess to contact the first semiconductor layer; and a dielectric layer formed on a side wall of at least one of the first opening, second opening or the recess, such that the protrusive portion does not contact the active layer and the second semiconductor layer, wherein the first semiconductor layer of first conductive type, the active layer, and the second semiconductor layer of the second conductive type form a light emitting structure, and wherein the first electrode is directly disposed on the semiconductor region and the first electrode is formed only over an upper surface of the semiconductor region.
