20090246361 | METHOD FOR MANUFACTURING DIELECTRIC ELEMENT - The present invention provides a method for manufacturing a dielectric element in which a dielectric film is formed by a chemical solution deposition method, with enhanced tolerance of the dielectric film of wet processes. A method for manufacturing a dielectric element comprises a process of heating a film of a solution of a precursor on a metal layer in an oxidizing atmosphere, to form a calcined film comprising a dielectric material generated from the precursor, and a process of annealing the calcined film to form a dielectric film comprising the dielectric material that has been crystallized. The dielectric material is a metal oxide which forms a perovskite-structure crystal having A sites and B sites. The solution of the precursor comprises an element occupying A sites and an element occupying B sites in the dielectric film, at a molar ratio of the element occupying A sites to the element occupying B sites of 0.85 or higher and 1.00 or lower. The annealing temperature of the solution film is 400 to 480° C. | 10-01-2009 |

20100260981 | DIELECTRIC DEVICE AND METHOD OF MANUFACTURING DIELECTRIC DEVICE - A dielectric device comprises a substrate made of a metal and an oxide dielectric layer mounted on a surface of the substrate. The surface of the substrate has metal oxide regions distributed like islands, while the oxide dielectric layer is in close contact with the substrate through the metal oxide regions. Since adhesion is higher in an area where the substrate and the oxide dielectric layer are in close contact with each other through the metal oxide regions distributed like islands on the surface of the substrate, the adhesion between the substrate and oxide dielectric layer in the dielectric device is enhanced. As compared with a case where a rough surface is formed on a metal foil, the metal oxide region and the substrate are inhibited from forming a rough surface, whereby leakage characteristics can be kept from being deteriorated by the rough surface. | 10-14-2010 |
