On precipitation of phosphorous in ion implanted silicon

Abstract
Electron microscope observations on phosphorous ion implanted psilicon after annealing at 800°C are reported. Heating for ½ hour after implantation of 2 × 1014 ions/cm2 at 20°C was found to produce dislocation loops and rod-like defects similar to those observed in boron implanted silicon. It was concluded that the rod-shaped defects are associated with phorphorous precipitation.
