Patent ID: 8304783

Claim:
A hybrid semiconductor device, comprising: a silicon carbide (SiC) semiconductor substrate; a PIN diode portion on the semiconductor substrate, the PIN diode portion having an anode contact on a first surface of the semiconductor substrate; a Schottky diode portion on the semiconductor substrate, the Schottky diode portion including a polysilicon layer on the semiconductor substrate and an ohmic contact on the polysilicon layer, the ohmic contact being different and spaced apart from the anode contact; a SiC layer on the SiC substrate; and a P-type SiC layer on the SiC layer, the SiC layer and the P-type SiC layer defining a trench that extends through the P-type SiC layer and exposes the SiC layer, wherein the polysilicon layer is on the exposed portion of the SiC layer, the ohmic contact is on the polysilicon layer and wherein the anode contact of the PIN diode portion is on the P-type SiC layer.
