Abstract

Effects of stress on the formation of titanium and nickel silicides on silicon-on-insulator (SOI) wafers have been investigated by sheet resistance measurements, glancing-angle x-ray diffraction analysis and transmission electron microscopy. Tensile stress was induced by the difference of thermal expansion coefficients of Si and SiO2. The thinner the top silicon layer, the higher tensile stress was induced. The formation of both Ti and Ni silicides was found to be enhanced by the tensile stress. The results indicated that the tensile stress promotes the atomic diffusion at the interface to facilitate the formation of metal silicides.
