Abstract

AbstractTransient enhanced diffusion is observed for P, As and Sb as a consequence of the recovery of the damage created by a silicon dose below the amorphization threshold. The phenomenon results more pronounced for low temperature furnace heating than after rapid thermal annealing and for those elements having a larger component of interstitialcy diffusion mechanism.A close correlation was found between the trends of the anomalous dopant diffusion and the implant damage evolution analyzed by X-ray diffraction. This evolution takes place via interstitial cluster dissolution.
