Abstract

The present description relates the formation of a first level interlayer dielectric material layer within a non-planar transistor, which may be formed by a spin-on coating technique followed by oxidation and annealing. The first level interlayer dielectric material layer may be substantially void free and may exert a tensile strain on the source/drain regions of the non-planar transistor.
