ABSTRACT:
In a semiconductor component with turn-off facility of the GTO type with direct pressure contact, a balancing of the local pressure distribution in the region of the cathode fingers (7) which results in an improved alternating load resistance and also in an extension of the allowable pressure range is achieved by structural matching of the anode metallization (4) to the gate-cathode structure on the cathode side.
