  • Patent number: 8399304
    Abstract: Methods for fabricating a capacitor are provided.

  • Publication number: 20120088110
    Abstract: This invention relates in part to processes wherein a polyamide polymer surface is chemically treated prior to applying a coating containing metal, and such metal coated polyamide articles. Treatment of the polyamide surface with an aqueous base wash after surface preparation with acid results in polyamide surfaces which provide superior adhesion to metals than polyamide surfaces which have not undergone a base wash before metal deposition.

  • Publication number: 20110311718
    Abstract: Disclosed is a method of making a thin-film dielectric, comprising providing a base metal foil, forming a barium titanate-based dielectric precursor layer over a base metal foil, pre-annealing the dielectric precursor layer and base metal foil, rapidly heating the pre-annealed dielectric precursor layer from a temperature of less than 530° C. to an annealing temperature of more than 800° C. in less than 15 seconds; and annealing the dielectric to form a crystalline barium titanate-based dielectric on the base metal foil, wherein the crystalline barium titanate-based dielectric has grains with an average grain size that is greater or equal to 50 nanometers. Also disclosed is a method of making a capacitor comprised of the thin-film dielectric formed on a base metal foil according to the method described above with a second conductive layer formed over the dielectric.

  • Publication number: 20100024181
    Abstract: The present invention relates to a process for the manufacture of capacitors on metal foil using chemical solution deposition of a barium/titanium precursor formulation. The metal foil substrate is annealed and subsequently polished prior to the precursor formulation deposition in order to obtain a desirable process yield of capacitors without short circuits across the dielectric.

  • Publication number: 20090238955
    Abstract: Provided are processes for the manufacture of capacitors. It is found that by using a nickel foil as the substrate and one electrode of the capacitor and by controlling the oxygen partial pressure in the range of 10?8 to 10?10 atmospheres during the crystallization heat treatment of the barium titanate, the leakage current can be maintained at adequate values without a reoxygenation step.

  • Publication number: 20090202738
    Abstract: Processes for manufacturing capacitors are provided. The processes include direct heating by passing a current through the metal foil substrate, which allows faster heating rates which in turn allow the growth of larger dielectric grains than obtained with conventional processes. Larger dielectric grains produce a capacitor with a higher specific capacitance.
