Abstract
The formation and distribution of NiSi2 in (111) silicon by Ni-ion imp lantation with a fluence of 1.1 X 10(17) cm-2 and an energy of 90 keV is studied as a function of the temperature during implantation. For t emperatures below 200-degrees-C, a buried layer of NiSi2 precipitates is formed. Increasing the temperature gradually from 200 to 350-degree s-C leads first to the formation of a double buried NiSi2 layer which with increasing temperature evolves into an epitaxial NiSi2 surface la yer. A tentative model to explain for the observed anomalous behavior is presented.
