Abstract:
1. A semiconductor light emitting device comprising: a substrate; a plurality of light emitting cells disposed on a top surface of the substrate, the light emitting cells each having a first-conductivity-type semiconductor layer, an active layer, and a second-conductivity-type semiconductor layer formed sequentially on the top surface of the substrate, wherein a region between the light emitting cells is defined as an isolation region removed to at least the active layer; a plurality of connection parts formed on the substrate with the light emitting cells formed thereon to connect the light emitting cells in a parallel or series-parallel configuration; and an insulation layer formed on the surface of the light emitting cells to prevent an undesired connection between the connection parts and the light emitting cells, wherein the light emitting cells comprise at least one defective light emitting cell, and at least one of the connection parts related to the defective light emitting cell is disconnected, wherein the light emitting cells are arrayed in a plurality of columns each having two or more light emitting cells, and the connection parts comprise: a plurality of first bonding pads disposed directly on the substrate and electrically connected to the first-conductivity-type semiconductor layer of the light emitting cells located at the one end of each column through the first connection part; and a plurality of second bonding pads disposed directly on the substrate and electrically connected to the second-conductivity-type semiconductor layer of the light emitting cells located at the other end of each column through the second connection part.
