Abstract: A non-planar semiconductor structure includes raised semiconductor structures, e.g., fins, having epitaxial structures grown on top surfaces thereof, for example, epitaxial silicon naturally growing into a diamond shape. The surface area of the epitaxial structure may be increased by removing portion(s) thereof. The removal may create a multi-head (e.g., dual-head) epitaxial structure, together with the neck of the raised structure resembling a Y-shape. Raised structures that are not intended to include an epitaxial structure will be masked during epitaxial structure creation and modification. In addition, in order to have a uniform height, the filler material surrounding the raised structures is recessed around those to receive epitaxial structures.

Abstract: A range of lowest, low and regular threshold voltages are provided to three p-type devices and three n-type devices co-fabricated on a same substrate. For the p-type devices, the range is achieved for the lowest using an additional thick layer of a p-type work function metal in a gate structure and oxidizing it, the low Vt is achieved with the thick p-type work function metal alone, and the regular Vt is achieved with a thinner layer of the p-type work function metal. For the n-type devices, the lowest Vt is achieved by implanting tantalum nitride with arsenic, argon, silicon or germanium and not adding any of the additional p-type work function metal in the gate structure, the low Vt is achieved by not adding the additional p-type work function metal, and the regular Vt is achieved with a thinnest layer of the p-type work function metal.

Tapered spacers along inner sidewalls of the top contact portion prior to filling allow for etching a narrower bottom trench down to the gate, and to the source/drain for silicidation prior to filling.
