Abstract

Short duration, incoherent light from a xenon lamp has been used to grow nickel silicides on silicon single crystals from evaporated nickel films. The formation of these silicides was studied by Rutherford Backscattering Spectrometry, channeling, sheet resistivity, and transmission electron microscopy as function of induced temperature (550– 775°C), exposure time (8– 25 sec), and silicon orientation (>111<, >110<, and >100<). Epitaxial NiSi2 films were formed for temperatures above ˜675°C whereas polycrystalline NiSi films were formed below this temperature.
