Abstract
A method of manufacturing a semiconductor device in a semiconductor body having a first surface and a second surface is proposed. Semiconductor device elements are formed in the semiconductor body by processing the semiconductor body at the first surface. A wiring area is formed over the first surface of the semiconductor body. The semiconductor body is attached to a carrier via the wiring area. Thereafter, ions are implanted through the second surface into the semiconductor body. The ions are ions of a doping element, or ions, which induce doping by complex formation, or ions of a heavy metal. A surface region of the semiconductor body at the second surface is irradiated with a plurality of laser pulses. Thereafter, the carrier is removed from the semiconductor body.
