Abstract
A semiconductor device which can be turned off via a first gate arranged at the cathode side including, a second gate structure comparable to the structure of the first gate arranged at the anode side. During the turning off, the charge carriers can be more rapidly drawn away from the base area of the component via the second anode-side gate and the turn-off behavior can thus be improved. In a dual gate device of the invention, a dual cascode circuit constructed with two MOSFETs.
