Claim Text:
1. An integrated circuit, comprising: a semiconductor body disposed between a top side and an opposite bottom side of the integrated circuit, the semiconductor body comprising a first wafer with an upper side proximate the top side of the semiconductor body and a second wafer with a lower side proximate the bottom side of the semiconductor body, the first and second wafers being joined to one another along an interface; a plurality of emitter zones of a first conductivity type formed in the semiconductor body; a drift zone of a second conductivity type formed in the semiconductor body proximate to the emitter zones, wherein the drift zone separates the plurality of emitter zones from the top side; at least one transistor cell, comprising: at least one emitter shorting contact of the second conductivity type disposed in the semiconductor body proximate at least one of the of emitter zones; and a silicide layer disposed between the emitter zones and the interface.
