Abstract(in English) | A new cobalt salicide technology using high-temperature sputtering and in-situ vacuum annealing has been developed. Sputtering at an elevated temperature and annealing without a break of vacuum were shown to promote in-situ silicidation and hence, suppress oxidation of the Co film. By using this technology, no linewidth dependence was observed for the sheet resistance down to 0.15μm wide gate electrode. The high temperature sputtering process was also observed to lead to the growth of epitaxial CoSi_2 thin films during subsequent anneals. A significant improvement in thermal stability was observed process and was attributed to the stability of the epitaxial silicide interfaces. When Co high temperature sputtering was performed, a very uniform and directional grain of CoSi_x can be formed. Consequently, epitaxial CoSi_2 is grown. |
