Title:
MATERIAL FOR MULTILAYER PRINTED CIRCUIT BOARD WITH BUILT-IN CAPACITOR, SUBSTRATE FOR MULTILAYER PRINTED CIRCUIT BOARD, MULTILAYER PRINTED CIRCUIT BOARD AND METHODS FOR PRODUCING THOSE
Document Type and Number:
WIPO Patent Application WO/2004/084597
Kind Code:
A1
Abstract:
A material for a multilayer printed circuit board with built-in capacitor is characterized in that a dielectric thin film having a relative dielectric constant of 10-2,000 and a thickness of 0.05-2 μm is formed on a surface of a metal foil. A substrate for a multilayer printed circuit board, a multilayer printed circuit board, and methods for producing them are also disclosed. By using such a material, a multilayer printed circuit board with built-in capacitor which is excellent in high-density wiring and economical efficiency can be obtained.
