Abstract: Integrated circuit metallization lines having a planar top surface but different vertical heights, for example to control intra-layer resistance/capacitance of integrated circuit interconnect. A hardmask material layer may be inserted between two thicknesses of dielectric material that are over a via metallization. Following deposition of the hardmask material layer, trench openings may be patterned through the hardmask layer to define where line metallization will have a greater height. Following the deposition of a thickness of dielectric material over the hardmask material layer, a trench pattern may be etched through the uppermost thickness of dielectric material, exposing the hardmask material layer wherever the trench does not coincide with an opening in the hardmask material layer. The trench etch may be retarded where the hardmask material layer is exposed, resulting to trenches of differing depth. Trenches of differing depth may be filled with metallization and then planarized.

Abstract: Conformal hermetic dielectric films suitable as dielectric diffusion barriers over 3D topography. In embodiments, the dielectric diffusion barrier includes a dielectric layer, such as a metal oxide, which can be deposited by atomic layer deposition (ALD) techniques with a conformality and density greater than can be achieved in a conventional silicon dioxide-based film deposited by a PECVD process for a thinner contiguous hermetic diffusion barrier. In further embodiments, the diffusion barrier is a multi-layered film including a high-k dielectric layer and a low-k or intermediate-k dielectric layer (e.g., a bi-layer) to reduce the dielectric constant of the diffusion barrier. In other embodiments a silicate of a high-k dielectric layer (e.g., a metal silicate) is formed to lower the k-value of the diffusion barrier by adjusting the silicon content of the silicate while maintaining high film conformality and density.

Abstract: IC interconnect structures including subtractively patterned features. Feature ends may be defined through multiple patterning of multiple cap materials for reduced misregistration. Subtractively patterned features may be lines integrated with damascene vias or with subtractively patterned vias, or may be vias integrated with damascene lines or with subtractively patterned lines. Subtractively patterned vias may be deposited as part of a planar metal layer and defined currently with interconnect lines. Subtractively patterned features may be integrated with air gap isolation structures. Subtractively patterned features may be include a barrier material on the bottom, top, or sidewall. A bottom barrier of a subtractively patterned features may be deposited with an area selective technique to be absent from an underlying interconnect feature. A barrier of a subtractively patterned feature may comprise graphene or a chalcogenide of a metal in the feature or in a seed layer.

Abstract: A memory structure includes conductive lines extending horizontally in a spaced apart fashion within a vertical stack above a base or substrate. The vertical stack includes a plurality of conductive lines, the first and second conductive lines being part of the plurality. A gate structure extends vertically through the first and second conductive lines. The gate structure includes a body of semiconductor material and a dielectric, where the dielectric is between the body and the conductive lines. An isolation material is on at least one side of the vertical stack and in contact with the conductive lines. The vertical stack defines a void located vertically between at the first and second conductive lines in the vertical stack and laterally between the gate structure and the isolation material. The void may extend along a substantial length (e.g., 20 nm or more) of the first and second conductive lines.
