Patent ID: 7423325

Claim:
A semiconductor component comprising: a semiconductor body with a first semiconductor layer of a first conduction type and a second semiconductor layer of a second conduction type, which is applied on the first semiconductor layer and forms a front side of the semiconductor body; in the second semiconductor layer, a first terminal zone of the second conduction type, a drift zone of the second conduction type, a channel zone of the first conduction type, which is formed between the first terminal zone and the drift zone, and a second terminal zone of the second conduction type, which is arranged at a distance from the channel zone in a lateral direction of the semiconductor body; a gate electrode arranged in a manner insulated from the semiconductor body and adjacent to the channel zone; and a plurality of auxiliary electrodes arranged at a distance from one another, and each formed in pillar-type fashion such that each auxiliary electrode has a length and has a cross-section, wherein the dimensions of the auxiliary electrode in the cross section extend in a lateral plane that is perpendicular to the length; wherein at least one of the plurality of auxiliary electrodes, which, proceeding from the front side, extends through the second semiconductor layer right into the first semiconductor layer and which is insulated from the semiconductor body; and wherein at least one of the plurality of auxiliary electrodes has no dimension in the lateral plane that extends substantially beyond any other dimension in the lateral plane.
