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.

Abstract: Embodiments of the disclosure are in the field of advanced integrated circuit structure fabrication and, in particular, 10 nanometer node and smaller integrated circuit structure fabrication and the resulting structures. In an example, an integrated circuit structure includes a fin. A first isolation structure separates a first end of a first portion of the fin from a first end of a second portion of the fin, the first end of the first portion of the fin having a depth. A gate structure is over the top of and laterally adjacent to the sidewalls of a region of the first portion of the fin. A second isolation structure is over a second end of a first portion of the fin, the second end of the first portion of the fin having a depth different than the depth of the first end of the first portion of the fin.

Abstract: Embodiments of the disclosure are in the field of advanced integrated circuit structure fabrication and, in particular, 10 nanometer node and smaller integrated circuit structure fabrication and the resulting structures. In an example, an integrated circuit structure includes a P-type semiconductor device above a substrate and including first and second semiconductor source or drain regions adjacent first and second sides of a first gate electrode. A first metal silicide layer is directly on the first and second semiconductor source or drain regions. An N-type semiconductor device includes third and fourth semiconductor source or drain regions adjacent first and second sides of a second gate electrode. A second metal silicide layer is directly on the third and fourth semiconductor source or drain regions, respectively. The first metal silicide layer comprises at least one metal species not included in the second metal silicide layer.

Abstract: Embodiments of the disclosure are in the field of advanced integrated circuit structure fabrication and, in particular, 10 nanometer node and smaller integrated circuit structure fabrication and the resulting structures. In an example, an integrated circuit structure includes a first isolation structure over a first end of a fin. A gate structure is over the fin and is spaced apart from the first isolation structure along the direction. A second isolation structure is over a second end of the fin, the second end opposite the first end. The second isolation structure is spaced apart from the gate structure. The first isolation structure and the second isolation structure both comprise a first dielectric material laterally surrounding a recessed second dielectric material distinct from the first dielectric material. The recessed second dielectric material laterally surrounds at least a portion of a third dielectric material different from the first and second dielectric materials.
