ABSTRACT:
A thyristor has a plurality of gate-controlled MIS-FET structures which serve the purpose of controlling emitter short-circuit paths with the objective of achieving stabilization short-circuits and, if necessary, quenching short-circuits. MIS-FET structures are disclosed which are effective, yet make economical use of surface area. In accordance with the invention, this is achieved since structures are provided at a plurality of recesses of the layered n-type emitter such that the electrode contacting the n-type emitter has recesses permitting it to contact the MIS-FET structures only on a border side.
