标 题 :Near-room temperature CVD synthesis of organic polymer/oxide dielectric nanocomposites
发明人：DESU SESHU B; SENKEVICH JOHN J
权利人:VIRGINIA TECH INTELL PROP
摘要:Nanocomposite thin films with low dielectric constants are made by the simultaneous deposition of an oxide dielectric and an organic polymer at near room temperatures. Suitable oxides include SiO 2 , and suitable organic polymers include poly(chloro-para-xylylene). The two dielectric materials, when deposited, form nanocomposites characterized by nanometer-sized domains of dielectric material. The nanocomposite thin films of this invention are useful as dielectric layers for interlevel dielectric (ILD) and intermetal dielectric (IMD) dielectrics in the manufacture of semiconductor devices as well as for thin films for flat panel displays, food wraps, hybrid ceramics, glass, hard disk drives, and optical disk drives. Additionally, the invention comprises semiconductor devices and semiconductor chips made incorporating nanocomposites deposited by chemical vapor deposition.

标题:Synthetic method for the synthesis of silicon polyether copolymers
发明人：CRIVELLO JAMES V; FAN MINGXIN
权利人:GEN ELECTRIC
摘要:The present invention is based on the discovery that various metal catalysts will catalyze the ring opening polymerization of epoxides to yield polyethers. The present invention therefore provides a method of making a polymeric product by ring-opening polymerization of heterocyclic epoxide monomer including the steps of preparing a mixture comprised of a catalyst; a Si--H containing compound; and at least one compound which is a heterocyclic epoxide containing monomer; and reacting the mixture at a temperature effective to promote ring-opening polymerization of the at least one compound to produce a polymeric product, preferably at room temperature. n The present invention additionally provides for the silicone-polyether compositions created by this method.

标题 :Process for synthesis of hybrid siloxy derived resins and crosslinked networks therefrom
发明人：GERBEC JEFFREY A
权利人:MITSUBISHI CHEM CORP
摘要:A hybrid siloxy derived resin and a method of making them and a method of applying them as a benign passivant on electrochemical electrodes is provided. These resins are made by the process of reacting a silane and an alkaline, transition metal or metalloid alkoxide, in the presence of a lewis acid. The methods described do not require further purification steps; heat; or strong acid/base catalysis to initiate hydrolysis.
