Abstract
A semiconductor device including at least one suspended channel structure of a silicon including material, and a gate structure present on the suspended channel structure. At least one gate dielectric layer is present surrounding the suspended channel structure, and at least one gate conductor is present on the at least one gate dielectric layer. Source and drain structures may be composed of a silicon and germanium including material. The source and drain structures are in contact with the source and drain region ends of the suspended channel structure through a silicon cladding layer.
