Claim Text:
1. A structure comprising: a plurality of Si fins on a buried oxide layer; a plurality of replacement metal gate structures extending over the plurality of Si fins and buried oxide, positioned orthogonal to the plurality of Si fins, the plurality of replacement metal gate structures comprising a gate dielectric, a metal gate and a nitride capping material, with nitride sidewall spacers; a doped Si epitaxial material adjacent to the nitride sidewall spacers and on the plurality of Si fins; a metal material adjacent to the plurality of replacement metal gate structures and on the doped epitaxial material, the metal material being planar with the capping material; insulator material on the metal material and the capping material; and contact studs in the insulator material and extending to the metal material to be in electrical contact with source and drain regions of the plurality of replacement metal gate structures, wherein an upper surface of the nitride capping material and an upper surface of the metal material are planar with one another.
