摘要:
A method of manufacturing a electrode foil composed of a valve metal layer of a first valve metal and a metal foil of a second valve metal supporting the valve metal layer, the method includes coating fine particles of the first valve metal with a resin to form composite fine particles, forming the composite fine particles into an aerosol, jetting the aerosol to the metal foil in an atmosphere under a reduced pressure, depositing the composite fine particles onto the metal foil to form a aerosol deposition layer, and removing selectively the resin from the aerosol deposition layer to form the valve metal layer.

The infrared absorption filter is composed of a polycarbonate resin which contains 20 to 100 mol % of a recurring unit having a fluorene skeleton represented by the formula (1) and 0 to 80 mol % of a recurring unit represented by the formula (2) and a coloring matter having infrared absorptivity.
摘要:
A circuit substrate comprises a lamination of plural resin insulation films and includes, on a surface and in an interior of the circuit substrate, plural interconnection layers. One of the plural resin insulation films is formed on a first conductor pattern constituting one of the plural interconnection layers in such a manner that a bottom principal surface of the resin insulation film makes a contact with a surface of the first conductor pattern, the resin insulation film including an opening defined by a sloped surface and exposing the first conductor pattern at the bottom principal surface. A ceramic high-K dielectric film is formed at a bottom of the opening in contact with the surface of the first conductor pattern, wherein there is formed a second conductor pattern constituting one of the plural interconnection layers on the resin insulation film so as to cover the sloped surface and in contact with a surface of the ceramic high-K dielectric film.
