Abstract
A method for fabricating a semiconductor body is presented. The semiconductor body includes a p-conducting zone, an n-conducting zone and a pn junction in a depth Tin the semiconductor body between the p-conducting zone and the n-conducting zone. The method includes providing the semiconductor body, producing the p-doped zone by the diffusion of an impurity that forms an acceptor in a first direction into the semiconductor body, and producing the n-conducting zone by the implantation of protons in the first direction into the semiconductor body into a depth T>Tand the subsequent heat treatment of the semiconductor body in order to form hydrogen-induced donors.
