Abstract:
Methods disclosed herein include replacing top portions of source and drain sections of a finFET structure having sidewalls and a first doping with doped amorphous silicon (a-Si) or amorphous silicon germanium (a-SiGe) having a second doping opposite to a first doping and that extends above the sidewalls. Disclosed method also include performing sub-melt laser annealing of the a-Si or a-SiGe to respectively form c-Si or c-SiGe to define the source and drain regions of the finFET. Unconverted a-Si or a-SiGe is removed. The source and drain regions so formed include expanded-area portions that extend beyond the tops of the sidewalls.

Claim (Index 7):
A finFET product formed by the process comprising:\n a) defining a c-Si fin having a first doping, opposite sides, a top section having a top portion with a top, and also having a source section, a drain section and a central section that separates the source and drain sections; b) covering the top and opposite sides of the central portion of the c-Si fin with a gate material to define the gate of the finFET; c) covering the sides of the source and drain sections with sidewalls made of a dielectric material, wherein the sidewalls have tops; d) replacing the top portions of the source and drain sections with a doped amorphous material comprising either doped amorphous silicon or doped amorphous silicon-germanium, the doped amorphous material having a second doping opposite to the first doping, wherein the doped amorphous material extends beyond the tops of the sidewalls; e) performing sub-melt laser annealing of the doped amorphous material to form a doped crystalline material comprising either crystalline silicon or crystalline silicon-germanium, the doped crystalline material having the second doping to define the source and drain regions of the finFET, wherein the source and drain regions include respective expanded-area portions that extend beyond the tops of the sidewalls; and f) removing any of the doped amorphous material that was not converted to the crystalline doped material in act e).
