ABSTRACT:
An integrated light-triggered and light-quenched static induction thyristor and fabrication process thereof adapted in such a manner that an integrated SIPT operates in the normal mode in order to enhance current gain, tail current generated at the light-quenching time is reduced in order to enhance turn-off gain, and an buried-gate type of light-triggered static induction thyristor and a photo-darlington circuit composed of a first and second static induction phototransistors are integrated on a high-resistivity substrate in order to permit manufacturing said thyristor compact as a whole in facilitated processes.
