Patent abstract
A light emitting diode (LED) has an n-type semiconductor layer, an active layer, a p-type semiconductor layer, and a transparent electrode layer. The LED includes a tunnel layer interposed between the p-type semiconductor layer and the transparent electrode layer, an opening arranged in the transparent electrode layer so that the tunnel layer is exposed, a distributed Bragg reflector (DBR) arranged in the opening, and an electrode pad arranged on the transparent electrode layer to cover the DBR in the opening.
