Patent ID: 8680565

Claim:
A light emitting diode (LED), comprising: a substrate; a first-type-doped layer, disposed on the substrate; a light emitting layer, disposed on the first-type-doped layer; a second-type-doped layer, disposed on the light emitting layer; a plurality of first grooves, each of which penetrating the second-type-doped layer and the light emitting layer so that a part of the first-type-doped layer is exposed, each of the first grooves having a first end and a second end; a second groove, connected to the first end of each first groove, and is penetrating the second-type-doped layer and the light emitting layer so that a part of the first-type-doped layer is exposed, and the second groove and the first grooves extending in different directions; an insulation layer, disposed on a part of the second-type-doped layer and extended to sidewalls of the first grooves and the second groove; a first contact, arranged in the first grooves and the second groove, and electrically connected to the first-type-doped layer; and a second contact, disposed on the second-type-doped layer, and electrically connected to the second-type-doped layer; wherein there is an interval between the second groove and edges of the second-type-doped layer and the light emitting layer.
