Abstract

A method of forming a MOS transistor, in which, a co-implantation is performed to implant a carbon co-implant into a source region and a drain region or a halo implanted region to effectively prevent dopants from over diffusion in the source region and the drain region or the halo implanted region, for obtaining a good junction profile and improving short channel effect, and the carbon co-implant is from a precursor comprising CO or CO2.
