Abstract
An integrated circuit includes a semiconductor body of a first conductivity type. The semiconductor body includes a first semiconductor zone of a second conductivity type opposite the first conductivity type. The first semiconductor zone extends to a surface of the semiconductor body. A second semiconductor zone of the first conductivity type is embedded in the first semiconductor zone and extends as far as the surface. A third semiconductor zone of the second conductivity type at least partly projects from the first semiconductor zone along a lateral direction running parallel to the surface. A contact structure provides an electrical contact with the first and second semiconductor zones at the surface. The second semiconductor zone is arranged, along the lateral direction, between the part of the third semiconductor zone which projects from the first semiconductor zone and a part of the contact structure in contact with the first semiconductor zone.
