  • Patent number: 7719818
    Abstract: An object of the present invention is to provide a material for forming a capacitor layer comprising a dielectric layer formed by any one of a sol-gel method, an MOCVD method, and a sputtering deposition method. The material can reduce a leakage current of a capacitor circuit. In order to achieve the object, a material for forming a capacitor layer comprising a dielectric layer between a first conductive layer to be used for forming a top electrode and a second conductive layer to be used for forming a bottom electrode, characterized in that the dielectric layer is a dielectric oxide film formed by any one of a sol-gel method, an MOCVD method, and a sputtering deposition method; and particles constituting the dielectric oxide film are impregnated with a resin component is employed.

  • Publication number: 20080310073
    Abstract: The present invention has an object to provide a method for forming an oxide dielectric layer, which dielectric layer is formed by applying the sol-gel method, and is hardly damaged by an etching solution and excellent in dielectric characteristics such as a large electric capacitance. To achieve the object, the forming method of an oxide dielectric layer by applying a sol-gel method characterized by being provided with the following processes (a) to (c) is employed. Process (a): A solution preparing process of preparing a sol-gel solution for manufacturing an aiming oxide dielectric layer. Process (b): A coating process wherein stages of the sol-gel solution coating on the surface of a metal substrate followed by drying in an oxygen-containing atmosphere followed by pyrolysis in an oxygen-containing atmosphere sequentially is made one unit step; the one unit step is repeated twice or more times; and a pre-baking stage at 550-deg.C to 1000-deg.
