A method is described for providing a nanostructure suspended above a substrate surface. The method includes providing a nanostructure encased in an oxide shell on a substrate and depositing a sacrificial material and a support material over the oxide encased nanostructure. Then, the sacrificial material is removed to expose the oxide encased nanostructure. Once the oxide encased nanostructure has been exposed, the oxide shell is removed from the oxide encased nanostructure such that the nanostructure is suspended above the substrate surface.

A field-effect transistor for a narrow-body, multiple-gate transistor such as a FinFET, tri-gate or Ω-FET is described. The corners of the channel region disposed beneath the gate are rounded n, for instance, oxidation steps, to reduce the comer effect associated with conduction initiating in the corners of the channel region.

A high-K thin film patterning solution is disclosed to address structural and process limitations of conventional patterning techniques. Subsequent to formation of gate structures adjacent a high-K dielectric layer, a portion of the high-K dielectric layer material is reduced, preferably via exposure to hydrogen gas, to form a reduced portion of the high-K dielectric layer. The reduced portion may be selectively removed utilizing wet etch chemistries to leave behind a trench of desirable geometric properties.
