Patent ID: 7683389

Claim:
A nitride-based semiconductor LED comprising: an anode composed of metal; a second n-type clad layer formed on a lower surface of the anode to come in contact with the anode; a first p-type clad layer being formed on a lower surface of the anode and a lower surface of the second n-type clad layer to come in contact with the anode and the second n-type clad layer; an active layer formed on a lower surface of the first p-type clad layer; a first n-type clad layer formed on an entire lower surface of the active layer; a second p-type clad layer formed on a lower surface of the first n-type clad layer such that the second p-type clad layer does not come in contact with the active layer entirely; and a cathode formed on a lower surface of the first n-type clad layer and a lower surface of the second p-type clad layer to come in contact with the first n-type clad layer and the second p-type clad layer, the cathode being composed of metal.
