Abstract:
A method for producing one of a multilayer diode and a thyristor including an emitter short-circuit structure, comprising the steps of:producing a multilayer arrangement from a semiconductor wafer; sawing grooves in a front of the multilayer arrangement so that a topmost layer of the multilayer arrangement is cut through; applying a back contact on a back of the multilayer arrangement opposite the front of the multilayer arrangement, and applying an emitter short-circuit contact on the front so that the topmost layer and a subjacent layer are short-circuited; and dicing the multilayer arrangement along a part of the grooves to produce separated multilayer chips such that in addition to the grooves along which the dicing is carried out, each multilayer chip includes at least one further groove not subject to the dicing step, wherein the at least one further groove and corresponding emitter short-circuit contact define an emitter short-circuit structure.
