Patent ID: 8669586

Claim:
A light emitting device comprising: a first electrode; a first semiconductor layer provided adjacent to first electrode, the first semiconductor layer having a prescribed first thickness in a first direction and a prescribed first width in a second direction, the first and second directions being different, the first semiconductor layer further including side surfaces; an active layer provided adjacent to the first semiconductor layer; a second semiconductor layer provided adjacent to the active layer; a second electrode adjacent to the second semiconductor layer; at least one current blocking layer at at least one side surface of the first semiconductor layer, the at least one current block layer having a second prescribed thickness in the first direction and a second prescribed width in second direction, the second prescribed thickness and the second prescribed width being smaller than the first prescribed thickness and the first prescribed width, respectively, and the entire second prescribed width of the at least one current blocking layer is provided within the first semiconductor layer; a second current blocking layer at a side of the second semiconductor layer; and a cover layer disposed over side surfaces of the first semiconductor layer, the active layer and the second semiconductor layer and between the second semiconductor layer and the second electrode, wherein the cover layer comprises a semiconductor material same as a material of at least one of the first semiconductor layer, the active layer or the second semiconductor layer.
