Abstract
We propose a channel doping technology for pMOSFET's in which Sb is multiply ion implanted to produce a uniform doping profile in the region deeper than the minimum projected range of the multiple ion implantation. We derive a threshold voltage model and show how to realize this uniform doping profile, which is verified with experimental data. We study the short-channel effect of this device using a two-dimensional (2-D) device simulator, and show that this transistor can readily operate with a gate length of down to 0.1 /spl mu/m.
