摘要： Metallization interconnect structures, integrated circuit devices, and methods related to high aspect ratio interconnects are discussed. A self assembled monolayer is selectively formed on interlayer dielectric sidewalls of an opening that exposes an underlying metallization structure. A first metal is formed on the underlying metallization structure and within only a bottom portion of the self assembled monolayer. The exposed portion of the self assembled monolayer is removed and a second metal is formed over the first metal.

摘要： Described herein are integrated circuit devices with conductive regions formed from MX or MAX materials. MAX materials are layered, hexagonal carbides and nitrides that include an early transition metal (M) and an A group element (A). MX materials remove the A group element. MAX and MX materials are highly conductive, and their two-dimensional layer structure allows very thin layers to be formed. MAX or MX materials can be used to form several conductive elements of IC circuits, including contacts, interconnects, or liners or barrier regions for contacts or interconnects.

摘要： 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.

摘要： Integrated circuit interconnect structures including an interconnect metallization feature with a liner material of a greater thickness between a fill metal and dielectric material, and of a lesser thickness between the fill metal and a lower-level interconnect metallization feature. The liner material may be substantially absent from an interface between the fill metal and the lower-level interconnect metallization feature. Liner material of reduced thickness at a bottom of the via may reduce via resistance and/or facilitate the use of a highly resistive liner material that may enhance the scalability of interconnect structures. In some embodiments, liner material is deposited upon dielectric surfaces with an area selective atomic layer deposition process. For single damascene implementations, both a via and a metal line may include a selectively deposited liner material.
