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: Integrated circuitry comprising an interconnect level with multi-height lines contacted by complementary multi-height vias. In some examples, a first line of a taller height is contacted by a first via of a shorter height while a second line of a shorter height is contacted by a second via of a taller height. The first and second vias and first and second lines may be subtractively defined concurrently from a same stack of conductive material layers such that the first via comprises a first conductive material layer, and the first line comprises second and third conductive material layers while the second via comprises the first and second conductive material layers and the second line comprises the third conductive material layer.

Abstract: An interconnect structure is disclosed. The interconnect structure includes a first line of interconnects and a second line of interconnects. The first line of interconnects and the second line of interconnects are staggered. The individual interconnects of the second line of interconnects are laterally offset from individual interconnects of the first line of interconnects. A dielectric material is adjacent to at least a portion of the individual interconnects of at least one of the first line of interconnects and the second line of interconnects.

Abstract: Adjacent interconnect lines are in staggered, vertically spaced positions, which accordingly reduces their capacitive coupling within one level of interconnect metallization. Short and tall interconnect via openings are landed on the vertically staggered interconnect lines. Cap material selectively deposited upon upper ones of the staggered interconnect lines limits over etch of the short vias while the tall vias are advanced toward lower ones of the staggered interconnect lines. The via openings of differing depth may be filled, for example with a single damascene metallization process that defines a co-planar top surface for all via metallization over the staggered, vertically spaced interconnect lines.
