Title:
PRODUCTION METHOD FOR SUBSTRATE WITH BUILT-IN CAPACITOR AND PRODUCTION METHOD FOR ELEMENT SHEETS THAT CAN BE USED IN AFOREMENTIONED PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/118307
Kind Code:
A1
Abstract:
Disclosed is a production method comprising an element sheet manufacturing step, a pasting step, an etching step, and a laminating step. In the element sheet manufacturing step, a metal foil (50) is used and a dielectric layer (13) is formed by the use of a power injection coating method on a predetermined region (54) in said metal foil (50), whereby said region becomes a first electrode layer for a capacitor element. A metal layer that acts as a second electrode layer for the capacitor element is then formed on said dielectric layer (13) to produce an element sheet with elements. In the pasting step, the element sheet is pasted on an insulation base material. In the etching step, a capacitor element composed of element sheet elements is formed on the insulation base material by etching on the metal foil (50). In the laminating step, a separate insulation base material is laminated on the insulation base material.
