Patent ID: 8716745

Claim:
A diode, comprising: a first layer of a first conductivity type having an upper surface, a lower surface, a first edge, and a second edge opposite to the first edge; a second layer of a second conductivity type being provided over the upper surface of the first layer, the second layer having an upper surface and a lower surface, the lower surface of the second layer facing the upper surface of the first layer; an anode being provided proximate to the lower surface of the first layer; a cathode being provided proximate to the upper surface of the second layer and extending from the first edge of the first layer towards the second edge of the first layer; a passivation layer being provided proximate to the upper surface of the second layer a doped region of the second conductivity type formed in the second layer extending from the first edge of the first layer towards the second edge of the first layer; and an isolation region of the first conductivity type formed in the second layer extending from the upper surface of the second layer to the upper surface of the first layer.
