    Abstract: Disclosed are a method of making a dielectric on a metal foil, and a method of making a large area capacitor that includes a dielectric on a metal foil. A dielectric precursor layer and the base metal foil are prefired at a prefiring temperature in the range of 350 to 650° C. in a moist atmosphere that also comprises a reducing gas. The prefired dielectric precursor layer and base metal foil are subsequently fired at a firing temperature in the range of 700 to 1200° C. in an atmosphere having an oxygen partial pressure of less than about 10−6 atmospheres to produce a dielectric. The area of the capacitor made according to the disclosed method may be greater than 10 mm2, and subdivided to create a multiple individual capacitor units that may be embedded in printed wiring boards. The dielectric is typically comprised of crystalline barium titanate or crystalline barium strontium titanate.

    Abstract: A multilayer printed wiring board 10 includes: a mounting portion 60 on the top surface of which is mounted a semiconductor element that is electrically connected to a wiring pattern 32, etc.; and a capacitor portion 40 having a high dielectric constant layer 43, formed of ceramic and first and second layer electrodes 41 and 42 that sandwich the high dielectric constant layer 43. One of either of the first and second layer electrodes 41 and 42 is connected to a power supply line of the semiconductor element and the other of either of the first and second layer electrodes 41 and 42 is connected to a ground line. In this multilayer printed wiring board 10, high dielectric constant layer 43 included in the layered capacitor portion 40, which is connected between the power supply line and the ground line, is formed of ceramic. With this structure, the static capacitance of the layered capacitor portion 40 can be high, and an adequate decoupling effect is exhibited even under circumstances in which instantaneous potential drops occur readily.

    Abstract: Disclosed herein are a coating solution for the formation of a dielectric thin film and a method for the formation of a dielectric thin film using the coating solution. The coating solution comprises a titanium alkoxide, a β-diketone or its derivative, and a benzoic acid derivative having an electron donating group. The method comprises spin coating the coating solution on a substrate to form a thin film and drying the thin film at a low temperature to crystallize the thin film. The titanium-containing coating solution is highly stable. In addition, the coating solution enables formation of a thin film, regardless of the kind of substrates, and can be used to form dielectric thin films in an in-line mode in the production processes of PCBs.
