Patent ID: 8707552

Claim:
A method of producing a multi layered printed circuit board, comprising: providing a core substrate as an integral unit comprising a body having a first surface and a second surface opposing the first surface, and a conductive layer formed on each one of the first and second surfaces of the body respectively; providing a capacitor as an integral unit separate from the core substrate, the capacitor including a first electrode, a first sputter film formed on the first electrode, an intermediate layer formed on the first sputter film by calcining a sol-gel film, a second sputter film on the intermediate layer, and a second electrode on the second sputter film; providing an insulation layer comprising resin, the insulation layer being separate from the core substrate and separate from the capacitor; arranging the insulation layer such that it is interposed between the core substrate and the capacitor; laminating the core substrate, the capacitor and the insulation layer together such that the insulation layer provides an interlayer insulation layer between the core substrate and the capacitor; and forming a build-up layer on the capacitor after the laminating.
