The ultra-fast diffusion of Cu and Ti atoms in a p+-type channel was observed in samples which were stressed using a high current density. The junction changed under a high current stress, and copper silicide formed there. The effects of a high current upon silicide line formation, and symmetrical end-of-range defect elimination near to the center of the p+-type channel, were considered.
