In-diffusion profiles of B were simulated on the basis of an integrated diffusion model that took account of the vacancy mechanism, the kick-out mechanism and the Frank-Turnbull mechanism. The simulations were performed using only 3 parameters; each of which had a clear physical meaning and a physically reasonable value, with no additional  ad hoc  hypothesis. These parameters corresponded to the diffusion of dopant species and of the point defects that contributed to dopant diffusion.
