A semiconductor component including a semiconductor substrate having a main electrode and a control electrode. The main electrode includes a groove in which is inserted a U-shaped insulation body. The control electrode is disposed in the groove and is insulated from the main electrode by the insulation body. A spring is provided in the groove between the control electrode and the insulation body and presses the control electrode against the semiconductor substrate. In this way, the control electrode is displaceable with respect to the insulation body in a direction perpendicular to the main surface of the semiconductor substrate.

Semiconductor components

In a metal-ceramic housing for a high-power GTO, a space-saving auxiliary cathode connection (5a) capable of carrying current is achieved in that it is constructed by embedding in the insulating ring (4) of the housing and is connected directly to the cathode contact plate (9) via its own connecting elements (11, 13, 15).
