  • Patent number: 10734379
    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.

  • Publication number: 20200235014
    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.
