Abstract
Low dose irradiation with 4 MeV protons was used for lifetime modifica tion in Si. The depth dependence of the induced effect was investigate d by Microwave Photoconductive Decay (mu-PCD) technique. By adopting a special sample structure it was possible to distinguish effects on li fetime caused by implantation defects and by carrier diffusion in the undamaged Si underneath. Limits are given when mu-PCD is applied to me asure lifetime changes set by deep implants.
