Title:
金属表面粗化層を有する金属層積層体及びその製造方法
Document Type and Number:
Japanese Patent JP5178064
Kind Code:
B2
Abstract:
Provided are a metal layer laminate that includes a roughened metal surface layer having a surface profile capable of strongly adhering to resin materials even when the surface roughness is small, and a simple method for producing a metal layer laminate having good adhesion to resin materials such as a resin substrate for a metal layer and an insulating resin film formed on the surface of a metal wiring portion. The metal layer laminate includes a metal layer, a resin thin film, and a roughened metal surface layer, wherein the resin thin film and the roughened metal surface layer are formed on the surface of the metal layer, a fractal-shaped interface structure appears between the resin thin film and the roughened metal surface layer, when the metal layer laminate is cut in a normal direction, and the interface structure has a fractal dimension of 1.05 to 1.50 as calculated using a box counting method with the measurement object region being set to from 50 nm to 5 μm and the box size (pixel size) being set to 1/100 or less of the measurement object region. The metal layer laminate is obtained by a production method including the steps of forming a resin thin film on the surface of a metal layer and subjecting the resin thin film-carrying metal layer to a plating process.
