    摘要: 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.

    摘要: A FinFET device includes a dielectric layer formed over a semiconductor substrate and having an upper dielectric layer surface. A fin of semiconductor material extends upwards from the substrate through an opening in the dielectric layer. A base portion of the fin, which is recessed below the upper dielectric layer surface, includes a base channel region that separates first and second base source/drain regions. An upper channel region extends upwards from the base channel region and terminates in an upper fin surface disposed above the upper dielectric layer surface. A gate electrode straddles the upper channel region and is separated from the upper channel region by a gate dielectric. First and second epitaxial source/drain regions meet the first and second base source/drain regions, respectively, at first and second interfaces, respectively. The first and second interfaces are recessed in the opening and arranged below the upper dielectric layer surface.
