Compact light emitting diode chip and light emitting device including the same

A light-emitting device, comprising:

• a substrate;
• a semiconductor stack on the substrate and comprising a first semiconductor layer, a second semiconductor layer, and an active layer between the first semiconductor layer and the second semiconductor layer;
• a via through the second semiconductor layer and the active layer to expose a second surface of the first semiconductor layer;
• a first pad electrode covering the via and contacting a upper surface of the first semiconductor layer;
• and
• a insulation layer comprising a first opening exposing the first semiconductor layer and a second opening exposing the second semiconductor layer;
• wherein the substrate comprises a surface exposed around the semiconductor stack and an edge side,
• wherein the first semiconductor layer comprises a first outside wall,
• wherein the second semiconductor layer comprises a second outside wall,
• wherein the insulation layer covers the first outside wall of the first semiconductor layer and the second outside wall of the second semiconductor layer, and contacting the surface of the substrate exposed around the semiconductor stack,
• wherein the insulation layer comprises a portion contacting the surface of the substrate, and wherein the portion of the third insulating layer comprises an edge side, and
• wherein the edge side of the substrate is spaced apart from the edge side of the insulating layer.
