  • Patent number: 6255228
    Abstract: A method for removing contaminants from a semiconductor wafer having a spin on coating of material. Contaminants are removed by applying a cleaning solution to the periphery, and preferably, the exposed backside of the wafer after the edge bead has been dissolved and removed. The cleaning solution is formulated to react chemically with unwanted coating material residue to form a compound that may be ejected from the periphery of the spinning wafer. Any residual solution or precipitate that is not ejected from the wafer may be rinsed away with water, preferably deoinized water. One exemplary use of this method is the removal of metallic contaminants that may be left on the periphery and backside of a wafer after the formation of ferroelectric film coatings. A cleaning solution comprising a mixture of hydrochloric acid HCl and water H2O or ammonium hydroxide NH4OH and water H2O is applied to the periphery of the spinning wafer.

  • Patent number: 6197437
    Abstract: A composite barrel for use in extrusion or injection molding is disclosed. The composite barrel includes an outer housing having a cylindrical bore that extends throughout the length of the outer housing. A wear-resistant lining is disposed on an interior surface that defines the cylindrical bore. The lining is fabricated from an alloy that includes a base metal and phosphorus and the lining may contain hard abrasion-resistant particulate, such as tungsten carbide. The base metal is nickel or cobalt or a mixture of nickel and cobalt. The alloy is typically applied by centrifugal casting and can be cast in a nitrogen-rich atmosphere without creating undesirable lining porosity. Such linings can be made for a fraction of the cost of comparable linings that must be cast under vacuum or in an atmosphere of argon.

  • Patent number: 6123989
    Abstract: A spinning rotor (1) with a spinning cup (2) has an interior surface coated with a nickel dispersion layer (6) of an essentially even layer thickness having a concentration of hard material grains (7) embedded therein which is clearly less at the surface of the fiber slide face (9) than in the rotor groove. The coating is produced by bathing the spinning cup in a nickel dispersion bath during the final stage of which the concentration of the hard material grains in the bath is reduced at least in the bathing area, while the spinning cup is moved in this bath and rotated around its longitudinal axis while maintaining the spinning cup in a spatial orientation relative to the bath wherein an imaginary plane passing through the rotor groove is at least approximately perpendicular to the surface of the nickel dispersion bath.

  • Patent number: 6040009
    Abstract: The present invention is to provide a low solvent content type-coating composition by which the resultant coatings with good scuff resistance or water resistance as well as good chipping resistance are produced, while the content of an organic solvent to be used can be much reduced. The low solvent content type-coating composition comprises a polyester oligomer having a hydroxyl group in an amount of 2.0 to 10.0 moles/Kg-resin, a number average molecular weight (Mn) of 300 to 1500, a weight average molecular weight (Mw) of 300 to 3000, and a ratio of a weight average molecular weight/a number average molecular weight (Mw/Mn) of 1 to 2.0, an amount of a modifying lactone being 31 to 85%, and an aliphatic hydrocarbon group of C4-22 which is not derived from lactones. The present invention is also to provide a process for coating a low solvent content type-coating composition on, for example, a base coating composition by a wet-on-wet coating.

  • Patent number: 5985365
    Abstract: An automated method and apparatus for galvanizing threaded rods, comprising conveying threaded rods while horizontally oriented through a bath of molten zinc, then simultaneously spinning the threaded rods in horizontal orientation at sufficient rotational velocity to remove excess molten zinc therefrom by centrifugal force and conveying the threaded rods to a cooling bath. The automated apparatus then conveys the zinc coated threaded rods through a cooling bath to solidify the molten zinc coating and then collects cooled zinc coated threaded rods to permit efficient removal thereof from the apparatus. A rotary conveyor mechanism of the automated apparatus conveys the threaded rods through a molten zinc bath and removes excess molten zinc therefrom by rolling the coated threaded rods down an inclined zinc removal platform.

  • Patent number: 5738787
    Abstract: The present invention features a filtration plate for use in a filter pan comprising a corrugated sheet having a series of alternately upwardly and downwardly opening channels and a reinforcing material bonded to surfaces of the downwardly opening channels. The reinforcing material is effective for strengthening the sheet and retaining heat in a manner effective to slow cooling of the filtration plate during washing and to reduce heat losses from the filtration plate during filtering. According to a preferred aspect of the invention, the corrugated sheet is a monolithic sheet of structural metal having a smooth upper filtration surface. The invention also provides a filter pan configured for use in filtration of a filtrate from solid particles. The filter pan comprises a filtration plate including a corrugated, monolithic sheet of structural metal having a series of alternately upwardly and downwardly opening channels.

  • Patent number: 5728626
    Abstract: A method of planarizing a non-planar substrate, such as filling vias and contact holes, spreads a suspension of a conducting material suspended in a liquid on a substrate. The suspension includes an organometallic material, preferably with particles of a polymerized tin or indium alkoxide. The material is spread by spinning the substrate after applying the suspension. The carrier liquid and organic groups are removed by baking and curing at elevated temperatures, thereby depositing the conductive material on the substrate in a layer which is more planar than the substrate and which has regions of greater and lesser thickness. A relatively brief etch step removes conductive material from regions of lesser thickness, leaving material filling vias or contact holes.
