Patent ID: 7294860

Claim:
A SiC semiconductor device comprising a vertical junction field effect transistor (JFET) comprising a source, a gate and a drain and a Schottky barrier diode (SBD) comprising an anode and a cathode, the device comprising: a SiC semiconductor substrate layer of a first conductivity type; a SiC drift layer of the first conductivity type on the substrate layer; a plurality of SiC source regions of the first conductivity type on the drift layer; a plurality of SiC gate regions of a second conductivity type different than the first conductivity type formed in the drift layer; a Schottky junction including a Schottky metal layer adjacent the drift layer; and a drain ohmic contact adjacent the substrate layer opposite the drift layer, a source ohmic contact adjacent the source region and a gate ohmic contact adjacent the gate region; wherein the Schottky metal layer is in electrical contact with the source ohmic contact, wherein the drain ohmic contact is a contact for the drain of the JFET and the cathode of the SBD and wherein the source ohmic contact is a contact for the source of the JFET and is electrically connected to the anode of the SBD.
