摘要：
A semiconductor device that includes cobalt-silicide based contacts is disclosed, as well as a process for making the same. Combinations of alloyed layers of Co—Ti—along with layers of Co—are arranged and heat treated so as to effectuate a silicide reaction on a silicon substrate. The resulting structures have extremely low resistance, and show little line width dependence, thus making them particularly attractive for use in semiconductor devices and processes.
