Original Abstract Submitted

A method of forming a semiconductor device includes forming a source/drain region and a gate electrode adjacent the source/drain region, forming a hard mask over the gate electrode, forming a bottom mask over the source/drain region, wherein the gate electrode is exposed, and performing a nitridation process on the hard mask over the gate electrode. The bottom mask remains over the source/drain region during the nitridation process and is removed after the nitridation. The method further includes forming a silicide over the source/drain region after removing the bottom mask.
