Abstract
Disclosed is a method for producing a transistor device and a transistor device. The method includes: forming a source region of a first doping type in a body region of a second doping type in a semiconductor body; and forming a low-resistance region of the second doping type adjoining the source region in the body region. Forming the source region includes implanting dopant particles of the first doping type using an implantation mask via a first surface of the semiconductor body into the body region. Implanting the doping particles of the first doping type includes a tilted implantation.
