Claim:
1. A semiconductor light-emitting device comprising: a semiconductor structure that comprises a first semiconductor layer, an active layer, and a second semiconductor layer, the semiconductor structure having a plurality of circular contact holes extended to the first semiconductor layer from the second semiconductor layer, side surfaces of the plurality of circular contact holes being slanted to a stacked direction of the first semiconductor layer, the active layer, and the second semiconductor layer; a first electrode layer and a second electrode layer that are disposed on the second semiconductor layer and are respectively electrically connected to the first semiconductor layer and the second semiconductor layer, the first electrode layer being electrically connected to the first semiconductor layer through a circular contact hole selected from the plurality of circular contact holes; an insulating layer that is formed on a top surface of the semiconductor structure to insulate the first electrode layer from the second electrode layer, the insulating layer being formed on a slanted side surface of the selected circular contact hole; an electrode layer that comprises a first electrode pad disposed on the first electrode layer and a second electrode pad disposed on the second electrode layer; and an insulating barrier layer that is disposed between the first electrode pad and the second electrode pad, wherein the insulating layer is disposed between the insulating barrier layer and the second electrode layer .
