Light emitting diode having a current blocking layer
Abstract:
A light emitting device according to embodiments includes a substrate, a light emitting structure disposed under the substrate and including a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer, a submount disposed to face the substrate, first and second metal pads disposed on the submount to be spaced apart from each other, a first bump disposed on the first metal pad, a plurality of second bumps disposed on the second metal pad to be spaced apart from each other, a first ohmic layer interposed between the first conductive semiconductor layer and the first bump, a second ohmic layer interposed between the second conductive semiconductor layer and the plurality of second bumps, a first spreading layer interposed between the first ohmic layer and the first bump, a second spreading layer interposed between the second ohmic layer and the plurality of second bumps, and a current blocking layer disposed in a maximum heating area of the second ohmic layer overlapping an area between the plurality of second bumps in a thickness direction of the light emitting structure such that the current blocking layer does not cut the second ohmic layer in a horizontal direction intersecting the thickness direction.
