A device and a method for forming a metal silicide is presented. A device, which includes a gate region, a source region, and a drain region, is formed on a substrate. A metal is disposed on the substrate, followed by a first anneal, forming a metal silicide on at least one of the gate region, the source region, and the drain region. The unreacted metal is removed from the substrate. The metal silicide is implanted with atoms. The implant is followed by a super anneal of the substrate.
