Rutherford backscattering spectrometry (RBS) is used to study the grow
th of Cr silicides formed by thin film reactions. Thin films of Cr wer
e deposited on phosphorus-implanted silicon and unimplanted silicon su
bstrates. Thermal annealing was subsequently carried out. The analysis
has shown a growth of a CrSi2 phase and allowed the determination of
formation kinetics. A retardation effect of the CrSi2 growth is observ
ed in the case of the phosphorus-implanted silicon substrate.
