Abstract: Integrated circuit (IC) structures, computing devices, and related methods are disclosed. An IC structure includes an interlayer dielectric (ILD), an interconnect, and a liner material separating the interconnect from the ILD. The interconnect includes a first end extending to or into the ILD and a second end opposite the first end. A second portion of the interconnect extending from the second end to a first portion of the interconnect proximate to the first end does not include the liner material thereon. A method of manufacturing an IC structure includes removing an ILD from between interconnects, applying a conformal hermetic liner, applying a carbon hard mask (CHM) between the interconnects, removing a portion of the CHM, removing the conformal hermetic liner to a remaining CHM, and removing the exposed portion of the liner material to the remaining CHM to expose the second portion of the interconnects.

Abstract: Gate-all-around integrated circuit structures having depopulated channel structures, and methods of fabricating gate-all-around integrated circuit structures having depopulated channel structures using multiple bottom-up oxidation approaches, are described. For example, an integrated circuit structure includes a vertical arrangement of nanowires. All nanowires of the vertical arrangement of nanowires are oxide nanowires. A gate stack is over the vertical arrangement of nanowires, around each of the oxide nanowires. The gate stack includes a conductive gate electrode.

Abstract: Embodiments described herein comprise extreme ultraviolet (EUV) reticles and methods of forming EUV reticles. In an embodiment, the reticle may comprise a substrate and a mirror layer over the substrate. In an embodiment, the mirror layer comprises a plurality of alternating first mirror layers and second mirror layers. In an embodiment, a phase-shift layer is formed over the mirror layer. In an embodiment, openings for printable features and openings for non-printable features are formed into the phase-shift layer. In an embodiment, the non-printable features have a dimension that is smaller than a dimension of the printable features.
