Abstract: Approaches for fabricating an integrated circuit structure including a titanium silicide material, and the resulting structures, are described. In an example, an integrated circuit structure includes a semiconductor fin above a substrate, a gate electrode over the top and adjacent to the sidewalls of a portion of the semiconductor fin. A titanium silicide material is in direct contact with each of first and second epitaxial semiconductor source or drain structures at first and second sides of the gate electrode. The titanium silicide material is conformal with and hermetically sealing a non-flat topography of each of the first and second epitaxial semiconductor source or drain structures. The titanium silicide material has a total atomic composition including 95% or greater stoichiometric TiSi2.

Abstract: Integrated circuits including MOSFETs with selectively recessed gate electrodes. Transistors having recessed gate electrodes with reduced capacitive coupling area to adjacent source and drain contact metallization are provided alongside transistors with gate electrodes that are non-recessed and have greater z-height. In embodiments, analog circuits employ transistors with gate electrodes of a given z-height while logic gates employ transistors with recessed gate electrodes of lesser z-height. In embodiments, subsets of substantially planar gate electrodes are selectively etched back to differentiate a height of the gate electrode based on a given transistor's application within a circuit.
