Abstract:
A method of fabricating a semiconductor device which comprises the steps of:(a) providing a substrate of semiconductor material;(b) forming a gate electrode over said substrate which is electrically isolated from said substrate;(c) applying an LDD and one of a pocket or halo implant to said substrate using said gate electrode as a mask, said implant extending under said gate;(d) forming a sidewall spacer on said gate electrode;(e) applying a source/drain implant over said one of a pocket or halo implant and neutralize the portion of the pocket or halo implant not extending under said gate and sidewall spacer; and(f) annealing the structure of step (e) to form source/drain regions in said substrate defining a channel in said substrate extending beneath said gate electrode and one of a pocket region or a halo region disposed under said gate electrode and sidewall spacer and between said channel and said source/drain regions.
