Abstract:
A field-controlled semiconductor component for use as a lateral-insulated gate bipolar transistor, the component comprising:a p-layer; an n-region having at least one p-well and an anode region, the n-region being arranged on a front side of the p-layer and the at least one p-well having a channel region controllable by a gate electrode; and at least one strongly n-doped cathode region being embedded in the at least one p-well, wherein: the at least one strongly n-doped cathode region is in a ring shape and runs parallel to an edge of the at least one p-well, the at least one strongly n-doped cathode region has at least one of an interruption and a recess in at least one location, and the at least one strongly n-doped cathode region of the at least one p-well adjacent to the anode region has an interruption along an entire side facing the anode region.
