Popis: As the methods of X-ray phase analysis and Auger spectroscopy have revealed, argon ions implanted into Cu-Si films cause the temperature of nucleation of silicides (Cu 5 Si and Cu 3 Si) to decrease by approximately 80 K. On implantation under mixing conditions the Cu 15 Si 4 phase, not observed in annealing of non-implanted film samples, grows together with the Cu 3 Si and Cu 5 Si phases. Kinetics of the growth of the phases is characterized by a parabolic dependence. Ion implantation does not change the type of the kinetics of phase growth. The new phase grows from grain boundaries into a grain throughout the entire thickness of Cu and Si layers. The growth rate of the phases depends on the position of the concentration maximum of ion-implantation-induced defects.
