Abstract
A semiconductor component having differently structured cell regions, and a method for producing it. For this purpose, the semiconductor component includes a semiconductor body. A first electrode on the top side of the semiconductor body is electrically connected to a first zone near the surface of the semiconductor body. A second electrode is electrically connected to a second zone of the semiconductor body. Furthermore, the semiconductor body has a drift path region, which is arranged in the semiconductor body between the first electrode and the second electrode. A cell region of the semiconductor component is subdivided into a main cell region and an auxiliary cell region, wherein the breakdown voltage of the auxiliary cells is greater than the breakdown voltage of the main cells.
