Abstract:
1. A light emitting device which has a semiconductor structure layer having a first semiconductor layer, a light emitting layer, and a second semiconductor layer of a conductivity type opposite to that of said first semiconductor layer sequentially laid one over another, a surface of said first semiconductor layer being a light extraction surface, said light emitting device comprising: a first groove extending from a second semiconductor layer side through said second semiconductor layer and said light emitting layer to said first semiconductor layer; a first ohmic electrode formed in contact with said first semiconductor layer in said first groove; an insulating layer covering a surface of said second semiconductor layer and at least the surface of part of said light emitting layer exposed in said first groove; a metal layer covering the surface of said insulating layer and connected to said first ohmic electrode; a second groove extending from a first semiconductor layer side through said first semiconductor layer and said light emitting layer to said second semiconductor layer; a second ohmic electrode formed in contact with said second semiconductor layer in said second groove; and a support body bonded to said metal layer via a junction layer.
