PROCEDE DE FABRICATION DE FILM CONDUCTEUR ANISOTROPE

摘要

The invention relates to a method for production of an anisotropic conductive film which contains a layer of electrically-insulating material and conductive inserts therethrough, said method comprising the following steps: a) forming at least one layer of material, having through-holes, on a substrate, said layer being called the perforated layer , and b) filling said through-holes to form conductive inserts. Said method also comprises producing a mask which at least partially covers a first end of said conductive inserts and etching the unmasked section of the end of said conductive inserts, in order to obtain conductive inserts with tapered ends. Said invention applies to the formation of components (chips, integrated circuits) with high interconnection density.
