<p>PURPOSE:To prevent the wrap, cracks and interlayer peeling-off of the substrate due to calcination by interposing a dielectric layer consisting of mixed compositions of both dielectric layers between high dielectric layer constituting a capacitor and a low dielectric layer prepared on at least one side of the high dielectric layer. CONSTITUTION:A lithium sulfate is prepared to be an aqueous solution as a sintering agent and it is added with a barium titanate. Then a green sheet CG-1 is formed as a high dielectric material and a conductor paste is printed on both sides of the sheet CG-1 to for a specified capacitor electrode pattern. On the other hand, a green sheet GG-1 is formed as a low dielectric material in which a ceramic phase of glass ceramic is made of alumina and a glass phase is made of boron and silicone. Further, a green sheet CGG-1 is formed as a mixed composition dielectric material composed of barium titanate and alumina. Finally, the sheet CGG-1 is interposed between the sheets CG-1 and GG-1, pressurized and calcined.</p> |
