Patent ID: 7244675

Claim:
An electrical connection method for electrically connecting an electrical connection portion of a first object and an electrical connection portion of a second object, said method comprising the steps of: providing an adhesive layer arrangement in which a first film-like adhesive layer composed of a plurality of conductive particles, a first binder containing said conductive particles, and a first filler is provided on the electrical connection portion of said first object and a second film-like adhesive layer composed of a second binder and a second filler is provided across a major surface of said first film-like adhesive layer; heating and pressurization at a temperature and under a pressure at which said second film-like adhesive layer has a viscosity lower than that of said first film-like adhesive layer; bringing together said electrical connection portions of said first and second objects sufficiently to cause said electrical connection portion of said second object to penetrate said second film-like adhesive layer for electrically connecting the electrical connection portion of said first object and the electrical connection portion of said second object by means of said conductive particles of said first film-like adhesive layer; and heating said resultant arrangement at a temperature sufficient to cause said first and second film-like adhesive layers to cure into sufficiently harden states.
