Abstract:
The improved contact resistance was obtained by the new barrier metal scheme such as CVD-Co/Ti/TiN process in the level of about half of that from CVD-Ti/TiN process. And the mechanism of contact silicidation of CVD-Co/Ti/TiN was investigated. Because Co silicide may prohibit the Si diffusion into Ti silicide and Si recess during TiCl 4 -based CVD-Ti process, and the inertness of Co silicide to the dopants, the improved contact resistance with uniform silicide morphology was obtained. Therefore, CVD-Co/Ti/TiN contact silicide process can be regarded as the next generation contact silicidation process.
