Abstract TEM observation was carried out on the phase transformation of CoSi along Co/ Si interface of the film grown on the Si substrate annealed at 250, 450 or 500℃respectively. CoSi is found to be the polycrystalline grains and no epitaxial relationship occurred between Si substrate and CoSi. The sequence of phase transformation for Co/Si interface in the annealing temperature range may be:250-450℃ 450-500℃Co2Si+ CoSi─→ CoSi─→CoSi+CoSi2(Correspondent: ZHANG Zaoli, Department of Material Physics, University of Science and TechnologyBeijing Beijing 100083)
