Abstract:
1. An integrated semiconductor diode arrangement comprising: an anode region of a first conductivity type; a cathode region of a second conductivity type different from the first conductivity type; wherein the anode region and the cathode region are formed in a semiconductor material region and are arranged in a first extension direction; the anode region further comprising an arrangement in a second and lateral extension direction in a cross section of alternately occurring first and second anode zones of the first conductivity type and of the second conductivity type, respectively, which are directly adjacent to one another, wherein the arrangement of the anode zone has an alternating sequence of three to ten anode zones; the anode region further comprising as part of the arrangement of the anode zones a first particular anode zone of the second conductivity type, which has a comparatively larger lateral extent than the further anode zones of the anode region of the same conductivity type, wherein, the first particular anode zone is configured to serve, during operating mode with ESD loading, as an emitter region of a bipolar transistor formed in parasite fashion in the integrated diode arrangement and wherein the alternately occurring first and second anode zones and said first particular anode zone of the anode region that are directly adjacent to one another are short-circuited; wherein the first particular anode zone of the second conductivity type constitutes an outermost or innermost anode zone of the second conductivity type with respect to the arrangement of the second anode zones of the second conductivity type along the lateral extension direction and wherein the first particular anode zone is located at the center or border of the semiconductor diode arrangement.
