TH22784A - Metallic film And capacitors containing such things - Google Patents

Abstract

Suitable metal film to form a capacitor Metal film according to This invention consists of a polymer base film. And the vapor binding layer with a significant portion of A1 and Zn was made on the polymer base film, the A1 content in the vapor binding layer will It continuously changes with its thickness direction, where the quantity A1 corresponds to the equation a2 < a3 < a1, where a1 represents the quantity A1 in the thickness as a percentage by weight relative to All the weights of A1 and Zn during the duty are between the bonded layers. And the polymer base layer, a2 represents the amount A1 in a percentage sense by weight relative to the total weight of A1 and Zn centered in the direction of layer thickness. And a3 represents the content of A1 in a percentage sense. Weight vs. total weight of A1 and Zn in the surface of the vapor binding layer.
