Claim:
1. An integrated circuit (IC) including one or more finFET devices, a finFET device comprising: a fin of semiconductor material extending upwards from a semiconductor substrate; first and second source/drain regions, which have a first doping type, spaced apart laterally from one another in the fin; a channel region disposed in the fin and physically separating the first and second source/drain regions from one another, wherein the channel region has a second doping type opposite the first doping type; a conductive gate electrode straddling the fin about the channel region and separated from the channel region by a gate dielectric; a shallow doped region, which has the first doping type, disposed in the fin along upper and sidewall regions of the fin, wherein the shallow doped region extends continuously under the gate electrode between opposing outer edges of the gate electrode; and first and second isolation regions arranged in the fin under respective outer edges of the gate electrode, the first and second isolation regions having inverted -u or -v shapes on opposite sides of the shallow doped region and separating the shallow doped region from the first and second source/drain regions, respectively.
