    摘要： A method of fabricating BEOL interconnect structures on a semiconductor device having a plurality of via contacts with low via contact resistance is provided. The method includes the steps of: a) forming a porous or dense low k dielectric layer on a substrate; b) forming single or dual damascene etched openings in the low k dielectric; c) placing the substrate in a process chamber on a cold chuck at a temperature about −200° C. to about 25° C.; d) adding to the process chamber a condensable cleaning agent (CCA) to condense a layer of CCA within the etched openings on the substrate; and e) performing an activation step while the wafer remains cold at a temperature of about −200° C. to about 25° C. The via contacts are very stable during thermal cycles and during operation of the semiconductor device.

    摘要： A method for forming a self aligned pattern on an existing pattern on a substrate comprising applying a coating of a solution containing a masking material in a carrier, the masking material having an affinity for portions of the existing pattern; and allowing at least a portion of the masking material to preferentially assemble to the portions of the existing pattern. The pattern may be comprised of a first set of regions of the substrate having a first atomic composition and a second set of regions of the substrate having a second atomic composition different from the first composition. The first set of regions may include one or more metal elements and the second set of regions may include a dielectric. The first and second regions may be treated to have different surface properties. Structures made in accordance with the method. Compositions useful for practicing the method.

    摘要： A method for forming a self aligned pattern on an existing pattern on a substrate comprising applying a coating of the masking material to the substrate; and allowing at least a portion of the masking material to preferentially attach to portions of the existing pattern. The pattern is comprised of a first set of regions of the substrate having a first atomic composition and a second set of regions of the substrate having a second atomic composition different from the first composition. The first set of regions may include one or more metal elements and the second set of regions may include a dielectric. The masking material may comprise a polymer containing a reactive grafting site that selectively binds to the portions of the pattern. The masking material may include a polymer that binds to the portions of the pattern to provide a layer of functional groups suitable for polymerization initiation, a reactive molecule having functional groups suitable for polymerization propagation, or a reactive molecule, wherein reaction of the reactive molecule with the portion of the pattern generates a layer having reactive groups, which participate in step growth polymerization. Structures in accordance with the method. Compositions for practicing the method.
