Abstract
A method for fabricating a semiconductor device includes the steps of: forming a gate structure on a substrate; forming a source/drain region adjacent to the gate structure; performing a first cleaning process; performing a first rapid thermal anneal (RTA) process to remove oxygen cluster in the substrate; forming a metal layer on the source/drain region; and performing a second RTA process to transform the metal layer into a silicide layer.
