Patent ID: 8629509

Claim:
A high power insulated gate bipolar junction transistor (“IGBT”), comprising: a wide band gap semiconductor bipolar junction transistor (“BJT”) having a collector, an emitter and a base; a MOSFET having a gate, a source region, a drain region and a channel region extending between the source region and the drain region, wherein the source region, the drain region and the channel region comprise a first wide band gap semiconductor material, and wherein the MOSFET is configured to provide a current to the base of the BJT; and a minority carrier diversion semiconductor layer between the base of the BJT and the gate of the MOSFET configured to divert a portion of the minority carrier current flow through the IGBT, the minority carrier diversion semiconductor layer having a conductivity type opposite the conductivity type of the base of the BJT and forming a heterojunction with the base of the BJT.
