Patent ID: 8829549

Claim:
A light emitting diode, comprising: a substrate; a first doped layer, disposed on the substrate; a light emitting layer, disposed on the first doped layer; a second doped layer, disposed on the light emitting layer; a plurality of first grooves, penetrating through the second doped layer and the light emitting layer, and thus a partial surface of the first doped layer is exposed; an insulating layer, disposed over a part of the second doped layer and extending to the sidewalls of the plurality of first grooves; a first contact, set in the plurality of first grooves and electrically connected to the first doped layer; and a second contact, set on the second doped layer and electrically connected to the second doped layer; wherein from a top view of the light emitting diode, one end of at least one of the plurality of first grooves extends to the edge of the first doped layer.
