Abstract:
Some embodiments relate to an integrated circuit (IC) including one or more finFET devices. A finFET includes a fin of semiconductor material extending upwards from a semiconductor substrate. First and second source/drain regions, which have a first doping type, are spaced apart laterally from one another in the fin. A channel region is disposed in the fin and physically separates the first and second source/drain regions from one another. The channel region has a second doping type opposite the first doping type. A conductive gate electrode straddles the fin about the channel region and is separated from the channel region by a gate dielectric. A shallow doped region, which has the first doping type, is disposed near a surface of the fin around upper and sidewall fin regions. The shallow doped region extends continuously under the gate electrode between outer edges of the gate electrode.
