Abstract:
1. A component comprising: a semiconductor body of a first conductivity type, having a first main surface and a second main surface opposite the first main surface; a first electrode arranged on the first main surface; a second electrode arranged on the second main surface; a semiconductor substrate of the first conductivity type, the semiconductor substrate adjoining the second electrode; a pedestal region of the first conductivity type, the pedestal region adjoining the semiconductor substrate; a first zone of the first conductivity type, the first zone adjoining the first electrode; a body zone of a second conductivity type, the body zone adjoining the first electrode; a drift zone of the first conductivity type that lies between the body zone and the pedestal region, wherein the drift zone is weakly doped relative to the first zone and the body zone; and at least one compensation region located in the drift zone configured continuously in pillar-type fashion and extends with its longitudinal direction parallel to a connecting direction between the first and the second electrodes, from the body zone to the pedestal region in a manner adjoining the pedestal region with the end of the compensation region, wherein the compensation region has a tapering cross-sectional area in the direction toward the second electrode, wherein the pedestal region is weakly doped relative to the semiconductor substrate and heavily doped relative to the drift zone; wherein the first conductivity type is an n conductivity type; and wherein the semiconductor substrate, the pedestal region, and the drift zone have a doping sequence: n
