  • Patent number: 6207522
    Abstract: Thin layer capacitors are formed from a first flexible metal layer, a dielectric layer between about 0.03 and about 2 microns deposited thereon, and a second flexible metal layer deposited on the dielectric layer. The first flexible metal layer may either be a metal foil, such as a copper, aluminum, or nickel foil, or a metal layer deposited on a polymeric support sheet. Depositions of the layers is by or is facilitate by combustion chemical vapor deposition or controlled atmosphere chemical vapor deposition.
    Type: Grant

    Date of Patent: March 27, 2001
    Assignee: MicroCoating Technologies
    Inventors: Andrew T. Hunt, Tzyy Jiuan Hwang, Helmut G. Hornis, Wen-Yi Lin
  • Patent number: 6208234
    Abstract: In thin layer resistors comprising a patch of a layer of resistive material on an insulating substrate and means at spaced apart locations on the patch, the resistive material is formed of 95 to 99.5 wt % of a zero valence metal and between 5 and 0.5 wt % of a dielectric material.

  • Patent number: 6193911
    Abstract: Precursor solutions are provided to produce thin film resistive materials by combustion chemical vapor deposition (CCVD) or controlled atmosphere combustion chemical vapor deposition (CACCVD). The resistive material may be a mixture of a zero valence metal and a dielectric material, or the resistive materials may be a conductive oxide.

  • Patent number: 6132653
    Abstract: A method for chemical vapor deposition using a very fine atomization or vaporization of a reagent containing liquid or liquid-like fluid near its supercritical temperature, where the resulting atomized or vaporized solution is entered into a flame or a plasma torch, and a powder is formed or a coating is deposited onto a substrate. The combustion flame can be stable from 10 torr to multiple atmospheres, and provides the energetic environment in which the reagent contained within the fluid can be reacted to form the desired powder or coating material on a substrate. The plasma torch likewise produces the required energy environment, but, unlike the flame, no oxidizer is needed so materials stable in only very low oxygen partial pressures can be formed.

  • Patent number: 6013318
    Abstract: A method for applying coatings to substrates using combustion chemical vapor deposition by mixing together a reagent and a carrier solution to form a reagent mixture, igniting the reagent mixture to create a flame, or flowing the reagent mixture through a plasma torch, in which the reagent is at least partially vaporized into a vapor phase, and contacting the vapor phase of the reagent to a substrate resulting in the deposition, at least in part from the vapor phase, of a coating of the reagent which can be controlled so as to have a preferred orientation on the substrate, and an apparatus to accomplish this method.

  • Patent number: 5863604
    Abstract: A method for applying coatings to substrates using combustion chemical vapor deposition by mixing together a reagent and a carrier solution to form a reagent mixture, igniting the reagent mixture to create a flame, or flowing the reagent mixture through a plasma torch, in which majority of the reagent is vaporized into a vapor phase, and contacting the vapor phase of the reagent to a substrate resulting in the deposition, at least in part from the vapor phase, of a coating of the reagent which can be controlled so as to have a preferred orientation on the substrate.
