Abstract:
A fin field-effect transistor (finFET) device having reduced capacitance, access resistance, and contact resistance is formed. A buried oxide, a fin, a gate, and first spacers are provided. The fin is doped to form extension junctions extending under the gate. Second spacers are formed on top of the extension junctions. Each is second spacer adjacent to one of the first spacers to either side of the gate. The extension junctions and the buried oxide not protected by the gate, the first spacers, and the second spacers are etched back to create voids. The voids are filled with a semiconductor material such that a top surface of the semiconductor material extending below top surfaces of the extension junctions, to form recessed source-drain regions. A silicide layer is formed on the recessed source-drain regions, the extension junctions, and the gate not protected by the first spacers and the second spacers.
