Abstract: Pitch division patterning approaches with increased overlay margin for back end of line (BEOL) interconnect fabrication, and the resulting structures, are described. In an example, a method includes forming a first plurality of conductive lines in a first sacrificial material formed above a substrate. The first plurality of conductive lines is formed along a direction of a BEOL metallization layer and is spaced apart by a pitch. The method also includes removing the first sacrificial material, forming a second sacrificial material adjacent to sidewalls of the first plurality of conductive lines, and then forming a second plurality of conductive lines adjacent the second sacrificial material. The second plurality of conductive lines is formed along the direction of the BEOL metallization layer, is spaced apart by the pitch, and is alternating with the first plurality of conductive lines. The method also includes removing the second sacrificial layer.

Abstract: Systems and methods for maskless gap (for example, air gap) integration into multilayer interconnects having one or more interconnect lines (for example, metal interconnect lines) embedded in a dielectric layer of the interconnects are described. In various embodiments, the described systems and methods may serve to reduce electrical shorting between adjacent vias in the interconnects. In one embodiment, a spacer layer may be provided to mask portions of an interlayer dielectric (ILD) in the interconnect. These masked portions of the ILD can protect regions between adjacent interconnect lines (for example, metal interconnect lines) from electrical shorting during subsequent metal layer depositions, for example, during a fabrication sequence of the interconnects. Further, the vias may enclose a gap (for example, an air gap) without the need for additional masking steps. Further, such gaps may be inherently self-aligned to the vias and/or spacer layers. Moreover, the gaps may act to reduce capacitance and thereby increase the performance (circuit timing, power consumption, etc.) of the interconnect.
