Abstract:
1. A method for producing a semiconductor component, said method comprising the following method steps of: providing a semiconductor body which has a front side, a back side, an inner region, an edge, an edge region which is arranged between the inner region and the edge, a first semiconductor zone of a first conduction type in the inner region and edge region and at least one second semiconductor zone of a second conduction type that is complementary to the first conduction type, said second semiconductor zone being arranged in the inner region in the region of the front, producing a connection electrode in the second semiconductor zone on the front of the semiconductor body, irradiating the front with high-energy particles using the connection electrode as a mask in order to produce recombination centers in the semiconductor body for the purpose of recombining charge carriers of the first and second conduction types, wherein the recombination centers form a recombination zone in the semiconductor body, the recombination zone being arranged beneath the connection electrode in the second semiconductor zone closer to the front and in the edge region in the first semiconductor zone farther away from the front such that the recombination zone extends deeper into the semiconductor body from the front in the first semiconductor zone than in the second semiconductor zone.
