Abstract:
Generally, in one embodiment, the present disclosure is directed to a method for forming a transistor. The method includes: implanting a substrate to form at least one of an n and p doped region; depositing an epitaxial semiconductor layer over the substrate; forming trenches through the epitaxial layer and partially through at least one of an n and p doped region; forming dielectric isolation regions in the trenches; forming a fin in an upper portion of the epitaxial semiconductor layer by partially recessing the dielectric isolation regions; forming a gate dielectric adjacent at least two surfaces of the fin; and diffusing dopant from at least one of the n and p doped regions at least partially into the epitaxial semiconductor layer to form a diffusion doped transition region adjacent a bottom portion of the fin.

Claim (Index 24):
A finFET transistor, comprising:\n a substrate comprising an n doped region and a p doped region; a first fin disposed above the n doped region and having a doped channel region having a first doping concentration; a second fin disposed above the p doped region and having a doped channel region having the first doping concentration; a first subfin region including a dopant diffusion inhibiting material intermediate the substrate and the channel of the first fin; a second subfin region including a dopant diffusion inhibiting material intermediate the substrate and the channel of the second fin; a first doped region beneath the first subfin region and having a second doping concentration; and a second doped region beneath the second subfin region and having the second doping concentration; wherein the second doping concentration is greater than the first doping concentration.
