    Abstract: A method of an aspect includes forming a directed self assembly alignment promotion layer over a surface of a substrate having a first patterned region and a second patterned region. A first directed self assembly alignment promotion material is formed selectively over the first patterned region without using lithographic patterning. The method also includes forming an assembled layer over the directed self assembly alignment promotion layer by directed self assembly. A plurality of assembled structures are formed that each include predominantly a first type of polymer over the first directed self assembly alignment promotion material. The assembled structures are each adjacently surrounded by predominantly a second different type of polymer over the second patterned region. The first directed self assembly alignment promotion material has a greater chemical affinity for the first type of polymer than for the second different type of polymer.

    Abstract: Techniques and structure are disclosed for providing a MIM capacitor having a generally corrugated profile. The corrugated topography is provisioned using sacrificial, self-organizing materials that effectively create a pattern in response to treatment (heat or other suitable stimulus), which is transferred to a dielectric material in which the MIM capacitor is formed. The self-organizing material may be, for example, a layer of directed self-assembly material that segregates into two alternating phases in response to heat or other stimulus, wherein one of the phases then can be selectively etched with respect to the other phase to provide the desired pattern. In another example case, the self-organizing material is a layer of material that coalesces into isolated islands when heated. As will be appreciated in light of this disclosure, the disclosed techniques can be used, for example, to increase capacitance per unit area, which can be scaled by etching deeper capacitor trenches/holes.

    Abstract: Subtractive self-aligned via and plug patterning for back end of line (BEOL) interconnects is described. In an example, an interconnect structure for an integrated circuit includes a first layer of the interconnect structure disposed above a substrate. The first layer includes a first grating of alternating metal lines and dielectric lines in a first direction. The dielectric lines have an uppermost surface higher than an uppermost surface of the metal lines. The interconnect structure further includes a second layer of the interconnect structure disposed above the first layer of the interconnect structure. The second layer includes a second grating of alternating metal lines and dielectric lines in a second direction, perpendicular to the first direction. The dielectric lines have a lowermost surface lower than a lowermost surface of the metal lines. The dielectric lines of the second grating overlap and contact, but are distinct from, the dielectric lines of the first grating. The metal lines of the first grating are spaced apart from the metal lines of the second grating.

    Abstract: Surface-aligned lithographic patterning approaches for back end of line (BEOL) interconnect fabrication, and the resulting structures, are described. In an example, an integrated circuit structure includes a substrate. A plurality of alternating first and second conductive lines is along a first direction of a back end of line (BEOL) metallization layer in a first inter-layer dielectric (ILD) layer above the substrate. A conductive via is on and electrically coupled to one of the conductive lines of the plurality of alternating first and second conductive lines, the conductive via centered over the one of the conductive lines. A second ILD layer is above the plurality of alternating first and second conductive lines and laterally adjacent to the conductive via. The second ILD layer has an uppermost surface substantially co-planar with the flat top surface of the conductive via.
