Abstract

See full text

A semiconductor component includes a semiconductor body having a surface and a cutout in the semiconductor body. The cutout extends from the surface of the semiconductor body into the semiconductor body in a direction perpendicular to the surface. The cutout has a base and at least one sidewall. The component further includes a layer on the surface of the semiconductor body and in the cutout. The layer forms a well above the cutout. The well has a well base, a well edge and at least one well sidewall. The at least one well sidewall forms an angle α in the range of 20° to 80° with respect to the surface of the semiconductor body. The layer has at least one edge which, proceeding from the well edge, extends in the direction of the surface of the semiconductor body.
