Patent number: 7442223Abstract: An ultra-efficient multilobal cross-sectioned fiber filter for chemical contaminant filtering applications is described. An absorptive chemically reactive reagent, preferably an acid or base and in liquid or an adsorptive chemically reactive reagent (an acid or base) in solid form, is disposed within longitudinal slots in each length of fiber. The reagent may be used alone or in conjunction with solid adsorptive particles which may also be utilized with the reagents in the longitudinal slots within the fibers. Reagents within the fibers remain exposed to a base-contaminated airstream passing through the filter. Base contaminants in the airstream, chemicals such as ammonium and amines (as well as particles), react with the acid reagent within the longitudinal slots of the fibers. As the contaminant and reagent react, the ammonium or amine becomes irreversibly absorbed (or adsorbed if reagent is a solid acid) to the liquid acid reagent and multilobal fiber.Type: GrantFiled: August 28, 2003Date of Patent: October 28, 2008Assignee: Honeywell International Inc.Inventors: Ron Rohrbach, Dan Bause, Peter Unger, Neil H. Hendricks, Jeff Miller, Adel Tannous, Randy R. LeClaire, William McGeever

Publication number: 20040192172Abstract: An oxidizing slurry for removal of low dielectric constant materials. The slurry is formed utilizing non-oxidizing particles with a separate oxidizing agent, oxidizing particles alone or reducible abrasive particles with a compatible oxidizing agent. The particles can be formed of a metal oxide, nitride, or carbide material, by itself or mixtures thereof, or can be coated on a core material such as silicon dioxide or can be coformed therewith. A preferred oxidizing slurry is multi-modal in particle size distribution.

Patent number: 6153525Abstract: A process for the formation and planarization of polymeric dielectric films on semiconductor substrates and for achieving high chemical mechanical polish removal rates when planarizing these films. A cured, globally planarized, polymeric dielectric thin film is produced on a semiconductor substrate by (a) depositing a polymeric, dielectric film composition onto a surface of a semiconductor substrate; (b) partially curing the deposited film; (c) performing a chemical mechanical polishing step to said partially cured dielectric film, until said dielectric film is substantially planarized; and (d) subjecting the polished film to an additional curing step. Preferred dielectric films are polyarylene ether and/or fluorinated polyarylene ether polymers which are deposited by a spin coating process onto a semiconductor substrate. A thermal treatment partially cures the polymer. A chemical mechanical polishing step achieves global planarization. Another thermal treatment accomplishes a final cure of the polymer.Type: GrantFiled: February 13, 1998Date of Patent: November 28, 2000Assignee: AlliedSignal Inc.Inventors: Neil H. Hendricks, Daniel L. Towery

Patent number: 6080526Abstract: A process for the preparation of substrates used in the manufacture of integrated circuits wherein spin-on low dielectric constant (low-k) polymer films are applied on semiconductor substrates. A non-etchback processing of spin-on low-k polymer films, without losing the low dielectric constant feature of the film, especially in between metal lines, is achieved utilizing electron beam radiation. A polymeric dielectric film is applied and dried onto a substrate and exposed to electron beam radiation under conditions sufficient to partially cure the dielectric layer. The exposing forms a relatively more hardened topmost portion of the dielectric layer and a relatively less hardened underlying portion of the dielectric layer.Type: GrantFiled: February 24, 1998Date of Patent: June 27, 2000Assignee: AlliedSignal Inc.Inventors: Jingjun Yang, Lynn Forester, Dong Kyu Choi, Shi-Qing Wang, Neil H.
