Abstract:
1. A method of forming a metal silicide comprising: forming a gate region, a source region, and a drain region in a substrate, wherein the forming the source region and the drain region further comprises forming one or more regions of dopants in the substrate; disposing a metal on the substrate; performing a silicide formation anneal to form a silicide on the gate region, the source region, and/or the drain region; removing an unreacted metal from the substrate; performing a post metal removal anneal after the removing the unreacted metal; implanting a plurality of ions into the silicide after the performing the post metal removal anneal, the plurality of ions being neither N-type ions nor P-type ions and wherein the implanting the plurality of ions occurs with an energy of less than 1 KeV; and performing a post implant anneal of the substrate, wherein the post implant anneal comprises a super anneal performed after the forming the source region and the drain region.
