    摘要: Provided is a method of inhibiting magnetically induced aggregation of ferrimagnetic and/or ferromagnetic nanoparticles by encapsulating the nanoparticles in a silica shell. The method entails coating magnetic nanoparticle surfaces with a polyacid polymer to form polymer-coated magnetic nanoparticles and treating the polymer-coated magnetic nanoparticles with a silica precursor to form uniform silica-coated magnetic nanoparticles. By controlling the thickness of the silica encapsulating the nanoparticles, the inherent magnetically induced aggregation of the nanoparticles can be completely inhibited.

    摘要: A method including providing Au-doped Co nanoparticles. The nanoparticles include a combination of non-ferromagnetic nanoparticles and weakly ferromagnetic nanoparticles. The nanoparticles each have an exterior surface. The surfaces of the nanoparticles are functionalized with 7-(5-uracil-ylcarbamoyl)heptanoic acid. A polymer is provided having a general formula including a uracil group. A dispersion is formed by agitating a solution of the nanoparticles. The solution is spin cast into a film. The film is heated under vacuum at a first temperature, TFM, resulting in inducing ferromagnetism in the non-ferromagnetic nanoparticles and converting the non-ferromagnetic nanoparticles to ferromagnetic nanoparticles, and resulting in enhancing ferromagnetism in the weakly ferromagnetic nanoparticles. The nanoparticles are aligned such that magnetic easy axes of the nanoparticles are oriented by applying a magnetic field to the dispersion while at a second temperature less than TFM. The axes align in a plane parallel to a plane of the film.

    摘要: The present invention provides a method of fabricating an interconnect structure in which a patternable low-k material replaces the need for utilizing a separate photoresist and a dielectric material. Specifically, this invention relates to a simplified method of fabricating single-damascene and dual-damascene low-k interconnect structures with at least one patternable low-k dielectric and at least one inorganic antireflective coating. In general terms, a method is provided that includes providing at least one patternable low-k material on a surface of an inorganic antireflective coating that is located atop a substrate. The inorganic ARC is liquid deposited and comprises a polymer that has at least one monomer unit comprising the formula M-R1 wherein M is at least one of Si, Ge, B, Sn, Fe, Ta, Ti, Ni, Hf and La and R1 is a chromophore. At least one interconnect pattern is formed within the at least one patternable low-k material and thereafter the at least one patternable low-k material is cured. The inventive method can be used to form dual-damascene interconnect structures as well as single-damascene interconnect structures.
