A dielectric device has a first conductor and a dielectric disposed thereon. An intermediate region is formed between the first conductor and dielectric. In the intermediate region, an additive different from the first conductor and dielectric and the dielectric are mixed with each other. The additive contains at least one element of Si, Al, P, Mg, Mn, Y, V, Mo, Co, Nb, Fe, and Cr.
Abstract:
A printed wiring board includes an insulating layer and a capacitor including a ceramic high dielectric layer being interposed between a first and a second electrode, and a semiconductor device mounting pad, including a first and a second pad, formed on an outermost resin insulating layer of the resin insulating layers. An underfill which covers an area larger than that of the high dielectric layer is formed, when the underfill covered area is projected along a lamination direction of the resin insulating layers to a face on which the high dielectric layer is formed. The capacitor is located immediately beneath the underfill covered area.
Abstract:
A board on which a wiring having an electrode pad is formed is prepared. A resist film is formed on the board in order to cover the wiring and then the resist film is left on the electrode pad through patterning. An inorganic insulating film is formed on the board in order to cover the wiring and then the resist film is removed, thereby removing the inorganic insulating film provided on the resist film to leave the inorganic insulating film between the wirings. A solder resist layer is formed on the board in order to cover the wiring and then the electrode pad is exposed.
