ABSTRACT:
A method of producing a gate turn-off thyristor includes producing a first n type impurity region, a second p type impurity region, a third n type impurity region, and a fourth p type impurity region produced in a semiconductor substrate providing a cathode electrode in contact with the first n type impurity region, providing a gate electrode in contact with the second p type impurity region, and an anode electrode which short-circuits the third and the fourth regions at the second main surface of the semiconductor substrate. Gold is diffused into the third region at a predetermined diffusion temperature thereby shortening the life time of carriers in the substrate.
