Patent ID: 7754590

Claim:
A method of manufacturing an implantation layer in a semiconductor substrate, comprising: increasing a path distance of a particle beam through the semiconductor substrate to a main implantation peak; and increasing an energy level of said particle beam through the semiconductor substrate, therefore forming an undamaged implantation layer in the semiconductor substrate, said implantation layer having a first thickness, wherein said implantation layer is formed at a predetermined depth of penetration relative to a top surface of the semiconductor substrate, wherein said first thickness of said implantation layer is larger than a second thickness of an implantation layer produced at the same predetermined depth of penetration relative to said top surface of the semiconductor substrate while employing a particle beam of non-increased path distance and non-increased energy level, wherein said particle beam is incident on said top surface of said semiconductor substrate, wherein a main donor peak is formed at said predetermined depth of penetration as a result of an annealing step carried out at a temperature less than 5000° C., after said implantation layer has been formed, and wherein said path distance is increased by using said particle beam having an angle of incidence different than 90° with reference to said top surface.
