Abstract
A thyristor which has outer emitter layers of opposite conductivity types and intermediate base layers of respective opposite conductivity types and metal-insulated-semiconductor emitter short circuit structures including a semiconductor region inserted in one of the outer emitters and doped opposite thereto and connected to the electrode carried thereby has an electrically conductive coating, connected to a terminal, carried on the boundary surface of the semiconductor body which contains the emitter layer having the MIS structure, a lateral zone of the conductive coating being insulated from the boundary surface and forming a gate electrode of the MIS structure and another zone which contacts the boundary surface and forms the trigger electrode.
