    摘要: A method and structure for forming a metallic capping interface between damascene conductive wires/studs and damascene conductive wiring line structures. The method forms a first insulative layer on a substrate layer, followed by forming damascene conductive wires/studs in the first insulative layer. A lower portion of each damascene conductive wire/stud is in contact with an electronic device (e.g., a field effect transistor), or a shallow trench isolation, that is within the substrate layer. A top portion of the first insulative layer is removed, such as by etching, such that an upper portion of the damascene conductive wires/studs remain above the first insulative layer. A metallic capping layer is formed on the upper portions of the damascene conductive wires/studs such that the metallic capping layer is in conductive contact with the damascene conductive wires/studs. Portions of the metallic capping layer between the damascene conductive wires/studs are removed to form a metallic cap on each damascene conductive wire/stud and to conductively isolate one or more of the damascene conductive wires/studs. A portion of the metallic capping layer may be removed from a particular damascene conductive wire/stud such that no metallic capping material remains conductively coupled to the particular damascene conductive wire/stud. A second insulative layer is formed on the first insulative layer such that the second insulative layer covers the metallic caps. Damascene conductive wiring lines are formed within the second insulative layer above the metallic caps and are conductively coupled to the metallic caps.

    摘要: A metal layer is deposited over a material layer. The metal layer includes an elemental metal that can be converted into a dielectric metal-containing compound by plasma oxidation or nitridation. A hard mask portion is formed over the metal layer. A plasma impermeable spacer is formed on at least one first sidewall of the hard mask portion, while at least one second sidewall of the hard mask portion is physically exposed. Plasma oxidation or nitridation is performed to convert physically exposed surfaces of the metal layer into the dielectric metal-containing compound. A sequence of a surface pull back of the hard mask portion, cavity etching, another surface pull back, and conversion of top surfaces into the dielectric metal-containing compound are repeated to form a hole pattern having a spacing that is not limited by lithographic minimum dimensions.

    摘要: An article including a microelectronic substrate is provided as an article usable during the processing of the microelectronic substrate. Such article includes a microelectronic substrate having a front surface, a rear surface opposite the front surface and a peripheral edge at boundaries of the front and rear surfaces. The front surface is a major surface of the article. A removable annular edge extension element having a front surface, a rear surface and an inner edge extending between the front and rear surfaces has the inner edge joined to the peripheral edge of the microelectronic substrate. In such way, a continuous surface is formed which includes the front surface of the edge extension element extending laterally from the peripheral edge of the microelectronic substrate and the front surface of the microelectronic substrate, the continuous surface being substantially co-planar and flat where the peripheral edge is joined to the inner edge.

    摘要: Gate to contact shorts are reduced by forming dielectric caps in replaced gate structures. Embodiments include forming a replaced gate structure on a substrate, the replaced gate structure including an ILD having a cavity, a first metal on a top surface of the ILD and lining the cavity, and a second metal on the first metal and filling the cavity, planarizing the first and second metals, forming an oxide on the second metal, removing the oxide, recessing the first and second metals in the cavity, forming a recess, and filling the recess with a dielectric material. Embodiments further include dielectric caps having vertical sidewalls, a trapezoidal shape, a T-shape, or a Y-shape.
