X-ray diffraction was performed {ital in} {ital situ} during annealing of a Co/Ti/Si(001) multilayer, which produced an epitaxial CoSi{sub 2} layer. The results indicate that the Ti layer did not stay intact during the reaction, and thus could not act like a membrane, moderating Co/Si interdiffusion. Strongly textured phases ({ital M}) formed prior to CoSi{sub 2} nucleation, and was unobservable upon completion of the anneal. Nucleation and growth of CoSi{sub 2} on Si(001) took place in the presence of {ital M}, new Co-Ti-(O) phases that were located at the metal/Si interface, and thus {ital M} might play an important role in the perfection of the silicide. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
