Fin cuts in neighboring gate and source or drain regions for advanced integrated circuit structure fabrication is described. For example, an integrated circuit structure includes a horizontal stack of semiconductor nanowire portions. A dielectric gate spacer is vertically over the horizontal stack of semiconductor nanowire portions. A gate isolation structure is laterally adjacent to a first side of the horizontal stack of semiconductor nanowire portions. A source or drain isolation structure is laterally adjacent to a second side of the horizontal stack of semiconductor nanowire portions.

Fin cut in neighboring gate and source or drain regions for advanced integrated circuit structure fabrication

An integrated circuit structure includes a first vertical arrangement of horizontal nanowires and a second vertical arrangement of horizontal nanowires. A first gate stack is over the first vertical arrangement of horizontal nanowires, and a second gate stack is over the second vertical arrangement of horizontal nanowires. An end of the second gate stack is spaced apart from an end of the first gate stack by a gap. A first dielectric gate spacer is laterally around the first gate stack and has a portion along an end of the first gate stack and in the gap. A second dielectric gate spacer is laterally around the second gate stack and has a portion along an end of the second gate stack and in the gap. The portion of the second dielectric gate spacer is laterally merged with the portion of the first dielectric gate spacer in the gap.

Contact over active gate (COAG) structures are described. In an example, an integrated circuit structure includes a plurality of gate structures above substrate, each of the gate structures including a gate insulating layer thereon. A plurality of conductive trench contact structures is alternating with the plurality of gate structures, each of the conductive trench contact structures including a trench insulating layer thereon. A remnant of a di-block-co-polymer is over a portion of the plurality of gate structures or the plurality of conductive trench contact structures. An interlayer dielectric material is over the di-block-co-polymer, over the plurality of gate structures, and over the plurality of conductive trench contact structures. An opening in the interlayer dielectric material. A conductive structure is in the opening, the conductive structure in direct contact with a corresponding one of the trench contact structures or with a corresponding one of the gate contact structures.

Discussed herein is gate spacing in integrated circuit (IC) structures, as well as related methods and components. For example, in some embodiments, an IC structure may include: a first gate metal having a longitudinal axis; a second gate metal, wherein the longitudinal axis of the first gate metal is aligned with a longitudinal axis of the second gate metal; a first gate contact above the first gate metal; a second gate contact above the second gate metal; and an unordered region having an unordered lamellar pattern, wherein the unordered region is coplanar with the first gate contact and the second gate contact.
