Patent ID: 8516690

Claim:
A method of manufacturing an anisotropic conductive joint package in which an anisotropic conductive film is joined to a conductive element of at least one material selected from the group consisting of gold (Au), silver (Ag), copper (Cu), aluminum (Al), magnesium (Mg), nickel (Ni), an indium-doped tin oxide (hereinafter abbreviated as “ITO”), molybdenum (Mo), iron (Fe), Pd (palladium), beryllium (Be) and rhenium (Re), to establish electrical connection between the anisotropic conductive film and the conductive element comprising the steps of, joining is conducted in a vacuum of at least 10 −1 Pa by thermocompression bonding at the temperature of from 180° C. to 300° C., the pressure per unit electrode area of from 1 MPa to 500 MPa, and the time of from 5 seconds to 10 minutes, wherein the anisotropic conductive film has an insulating base and conductive paths composed of a conductive material, insulated from one another, and extending through the insulating base in the thickness direction of the insulating base, one end of each of the conductive paths is exposed on one side of the insulating base, and the other end of each of the conductive paths is exposed on the other side thereof, wherein the density of the conductive paths is 3,000,000 pieces/mm 2 or more, and the insulating base is a structure composed of an anodized film of an aluminum substrate, having micropores, and wherein the micropores do not have a branched structure in their depth direction.
