Abstract: A first etch stop layer is deposited on a plurality of conductive features on an insulating layer on a substrate. A second etch stop layer is deposited over an air gap between the conductive features. The first etch stop layer is etched to form a via to at least one of the conductive features.

Abstract: Techniques related to multi-pass patterning lithography, device structures, and devices formed using such techniques are discussed. Such techniques include exposing a resist layer disposed over a grating pattern with non-reflecting radiation to generate an enhanced exposure portion within a trench of the grating pattern and developing the resist layer to form a pattern layer having a pattern structure within the trench of the grating pattern.

Abstract: A method including patterning a thickness dimension of an interconnect material into a thickness dimension for a wiring line with one or more vias extending from the wiring line and introducing a dielectric material on the interconnect material. A method including depositing and patterning an interconnect material into a wiring line and one or more vias; and introducing a dielectric material on the interconnect material such that the one or more vias are exposed through the dielectric material. An apparatus including a first interconnect layer in a first plane and a second interconnect in a second plane on a substrate; and a dielectric layer separating the first and second interconnect layers, wherein the first interconnect layer comprises a monolith including a wiring line and at least one via, the at least one via extending from the wiring line to a wiring line of the second interconnect layer.
