With respect to an interface which delimits the semiconductor body in regions in a vertical direction, on that side of said interface which is remote from the active region, the semiconductor body has a web-like region extending in a vertical direction between the interface and a surface of the semiconductor body. The indicator layer has a material composition that differs from that of the material of the web-like region which adjoins the indicator layer. A distance between the indicator layer and the surface is at most of the same magnitude as a distance between the interface and the surface.
