Abstract: An integrated circuit includes a first device having a first source or drain region, and a second device having a second source or drain region that is laterally adjacent to the first source or drain region. A conductive source or drain contact includes (i) a lower portion in contact with the first source or drain region, and extending above the first source or drain region, and (ii) an upper portion extending laterally from above the lower portion to above the second source or drain region. A dielectric material is between at least a section of the upper portion of the conductive source or drain contact and the second source or drain region. In an example, each of the first and second devices is a gate-all-around (GAA) device having one or more nanoribbons, nanowires, or nanosheets as channel regions, or is a finFet structure having a fin-based channel region.

Abstract: An integrated circuit interconnect level including a lower metallization line vertically spaced from upper metallization lines. Lower metallization lines may be self-aligned to upper metallization lines enabling increased metallization line width without sacrificing line density for a given interconnect level. Combinations of upper and lower metallization lines within an interconnect metallization level may be designed to control intra-layer resistance/capacitance of integrated circuit interconnect. Dielectric material between two adjacent co-planar metallization lines may be recessed or deposited selectively to the metallization lines. Supplemental metallization may then be deposited and planarized. A top surface of the supplemental metallization may either be recessed to form lower metallization lines between upper metallization lines, or planarized with dielectric material to form upper metallization lines between lower metallization lines. Vias to upper and lower metallization line may extend another metallization level.

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: Techniques to form semiconductor device conductive interconnections. In an example, an integrated circuit includes a recessed via and a conductive bridge between a top surface of the recessed via and an adjacent source or drain contact. A transistor device includes a semiconductor material extending from a source or drain region, a gate structure over the semiconductor material, and a contact on the source or drain region. Adjacent to the source or drain region, a deep via structure extends in a vertical direction through an entire thickness of the gate structure. The via structure includes a conductive via that is recessed below a top surface of the conductive contact. A conductive bridge extends between the contact and the conductive via such that the conductive bridge contacts a portion of the contact and at least a portion of a top surface of the conductive via.

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: Techniques are disclosed that enable independent control of interconnect lines and line end structures using a single mask. The techniques provided are particularly useful, for instance, where single mask lithography processes limit the scaling of line end structures. In some embodiments, the techniques can be implemented using a liner body and multiple angled etches of the liner body to provide a line end structure comprised of a remaining portion of the liner body. In such cases, the line end structure material enables an etch rate that is slower than the etch rate of surrounding insulator materials. Furthermore, the line end structure can be of minimal size not attainable using conventional single mask processes. In other embodiments, the techniques can be implemented using a hardmask that includes hardmask features defining lines, and one or more angled etches of the hardmask to provide line end structure(s) of minimal size.
