| Summary: | The impact of the thermal budget on the introduction and dissociation of hydrogen-related donor profiles in high purity silicon implanted with protons in the energy range of MeV is investigated. The hydrogen-related donors are radiation-induced defect complexes decorated by the implanted hydrogen. The appearance of the donor profiles is limited to the annealing temperature regime between about 350 °C and 500 °C. The activation of the doping profiles is limited by the diffusion of the implanted hydrogen from the end-of-range region throughout the radiation-induced damage profile. This formation process is adequately described by a diffusion model with an effective activation energy of 1.2 eV. The thermal stability of the hydrogen-related donor profiles is limited by the dissociation of the donors. The deactivation of the doping is modeled by two hydrogen-related donor species with effective dissociation energies of 2.6 eV and 3 eV. The formation and dissociation mechanisms described in the present study define the upper and lower limits of the post-implantation thermal budget, respectively, for a sensible use of proton implantation doping in crystalline silicon. |
