Title:
ANISOTROPIC CONDUCTIVE FILM AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2005/096442
Kind Code:
A1
Abstract:
An anisotropic conductive film, which is applicable to a narrower pitch of an object to be connected, while maintaining connection reliability, is provided at a low cost compared with the conventional ones. A method for manufacturing such anisotropic conductive film is also provided. The anisotropic conductive film is provided with a porous film. The film has many hole parts which penetrate in the film thickness direction, being arranged in a honeycomb state with their inner wall surfaces bent in the external direction, and are formed of a polymer. The film is also provided with a conductive material applied in the holes of the porous film, and an adhesive layer covering the both sides of the porous film. The porous film is formed by a method wherein the polymer is melt in a volatile organic solvent which does not mix with water and a supporting board made by casting the polymer solution is permitted to exist under a high moisture condition.
