Abstract:
FinFET devices including III-V fin structures and silicon-based source/drain regions are formed on a semiconductor substrate. Silicon is diffused into the III-V fin structures to form n-type junctions. Leakage through the substrate is addressed by forming p-n junctions adjoining the source/drain regions and isolating the III-V fin structures under the channel regions.

Claim (Index 25):
A structure comprising:\n a semiconductor substrate; a plurality of columns extending from the semiconductor substrate, the columns being separated by a plurality of recesses, each of the columns including a III-V base epitaxially formed on the semiconductor substrate and a III-V fin structure, each III-V fin structure being positioned on the III-V base, and each of the recesses extending down to the semiconductor substrate; a plurality of gate structures, each of the plurality of gate structures adjoining one of the III-V fin structures; a silicon-based layer within each of the recesses and adjoining the semiconductor substrate, the silicon-based layer being epitaxially formed on the semiconductor substrate and including undoped regions adjoining the III-V fin structures, and a plurality of n-type junctions adjoining the undoped regions of the silicon-based layer, each of the junctions including silicon diffused within the III-V fin structures and a group V element diffused within the undoped regions.
