Gettering sites comprising dislocations and voids have been formed in silicon at a depth of 0.8 μm by room-temperature implantation with 80 keV energy protons to a fluence of 3 × 1016 cm−2, followed by annealing at a temperature of 800 °C for 20 min. Copper was evaporated onto the Si surface then diffused by heating at 600 °C for times between 5 and 60 min. Subsequently, positron annihilation measurements were used to profile the samples for void and (or) vacancy content. Rutherford backscattering quantified metal trapping out of the diffusion profile to the gettering sites. Transmission electron micrographs identified Cu trapping at both dislocations and voids. Cavities exhibit different morphologies between the empty (void) and filled condition; the latter are strongly faceted and found to contain bulk silicide.

ABSTRACTTwenty years of research have now been devoted to investigating reaction products obtained by annealing metal-layer/silicon structures. A wide variety of cases have been analyzsed and a considerable amount of data has been produced. Despite the vast amount of information available, several aspects concerning phase formation and kinetic processes are not yet well established. The purpose of this paper is to investigate the mechanisms of phase formation and to show the importance of kinetic factors in the appearance of various compounds. Results will be shown for a single metal layer deposited on silicon, for bilayers. and for alloys. Depending upon the starting structure, metal-rich or silicon-rich silicides can be formed. Moreover, by modifying the boundary conditions, it is possible to change the growth kinetics of the silicide phase that forms.

ABSTRACTWe have studied the formation of platinum silicide layers by ion implantation and annealing, and have determined the dependence of platinum silicide phase formation on ion implantation conditions and substrate orientation. The results indicate that in most cases, the ion implanted layer consists of PtSi phase. However, depending on the implantation and annealing conditions and substrate orientation, other phases, including Pt2Si, Pt3Si, and Pt12Si5, as well as Si and Pt microcrystals, also form.
