Thyristor with improved switch on / off characteristics and method of manufacturing the same

摘要

A thyristor, in particular a GTO, has a high recombination rate zone (ZHR) generated over a large surface of its n-base (3, 3') by irradiation with protons or helium nuclei at the anode side. The charge carrier lifetime is not homogeneous in the vertical direction and the site where the charge carriers are diminished in the n-base is near the p+-emitter.
