Process for the manufacture of a thyristor with the regions of the emitter, base emitter, base cathode and cathode; and thyristor with an emitter, base of emitter, base cathode irradiated by radiation Electronica

摘要

pA method for improving the relationship of reverse recovery charge Qrr, reverse recovery time tq, and forward voltage drop VTM comprises the steps of irradiating the thyristor with a first predetermined dosage of light ions, preferably alpha or proton particles and then irradiating the thyristor with a second predetermined dosage of electron particles./p[EP0032386A2]
