Claim:
1. A stacked hybrid device comprising: a transistor, the transistor being a normally-off silicon carbide field effect device comprising a source, a drain, and a transistor gate, the transistor being a discrete chip comprising a backside drain connection; and a bipolar switch, the bipolar switch being a normally-on silicon carbide n-channel static-induction thyristor comprising a switch gate terminal, a thyristor anode, and a thyristor cathode, the bipolar switch being a discrete chip comprising a top side anode bonding pad and a backside cathode connection; wherein: the backside drain connection is conductively bonded directly to the top side anode bonding pad using a die attach material; and the switch gate terminal is connected to the source, such that operation of the stacked hybrid device is controlled via the gate of the transistor.
