Claim Text:
1. A field effect component, comprising a semiconductor body, which extends in an edge zone from a rear side as far as a surface of the semiconductor body, and which comprises a semiconductor mesa, which extends in a vertical direction, which is perpendicular to the rear side and/or the surface, as far as a semiconductor mesa top side arranged at a height above the surface, wherein the semiconductor body in a vertical cross section further comprises: a drift region, which extends at least in the edge region as far as the surface and which is arranged partly in the semiconductor mesa; and a body region, which is arranged at least partly in the semiconductor mesa and which forms a first pn junction with the drift region, said first pn junction extending between two sidewalls of the semiconductor mesa, wherein a vertical distance between the first pn junction and the semiconductor mesa top side varies in a horizontal direction and assumes a largest value in a central zone spaced apart from the two sidewalls, and wherein the largest value is at least 70% of the height.
