Abstract:
Disclosed herein are various methods of forming replacement gate structures on semiconductor devices and devices incorporating such gate structures. In one example, the device includes a plurality of gate structures and at least one sidewall spacer positioned proximate each of the gate structures, a metal silicide region in a source/drain region formed in a substrate, wherein the metal silicide region extend laterally so as to contact the sidewall spacer positioned proximate each of the gate structures and a conductive contact positioned between the gate structures that conductively contacts the metal silicide region, wherein the conductive contact has a bottom portion that is wider than an upper portion of the conductive contact.
