ABSTRACT:
A housing for a semiconductor device is disclosed. In an exemplary embodiment of the present invention, the housing comprises a semiconductor substrate that is arranged between two contact elements, one contact element forming an anode contact element and another contact element forming a cathode contact element, the semiconductor substrate having, on at least one surface, a gate electrode that is contacted by a gate contact element, the first contact element forming a surface arranged across from the gate electrode and at a distance from the gate electrode. Also included is at least one driver unit for generating a gate current, the driver unit comprising a first terminal that is contacted with the gate contact element, and a second terminal that is contacted with a first of the two contact elements. A housing according to an exemplary embodiment of the present invention additionally comprises a spring element arranged so that a spring force brings the gate contact element into pressure contact with the gate electrode and, at substantially the same time, the spring force brings the second terminal of the driver unit into pressure contact with the surface of the first contact element that is located across from the gate electrode.
