Abstract:
1. A method comprising: depositing a gate oxide film and polysilicon over a silicon substrate; patterning at least one of said gate oxide film and polysilicon to form a gate electrode; forming a spacer over said gate electrode; simultaneously performing a source/drain implant and an amorphization implant over the substrate, wherein said simultaneously performing source/drain implant and amorphization implant comprises molecule implant using ionized molecules; depositing an insulating film after performing said source/drain implant and amorphization implant; exposing at least a portion of said source/drain and a portion of said gate electrode disposed under said insulating film by etching regions of said insulating film; applying a metal film over said insulating film and the exposed portion of said source/drain and gate electrode; and forming silicide over the etched regions by performing heat treatment over said source/drain and gate electrode.
