Patent ID: 7901768

Claim:
A multilayer anisotropic conductive adhesive, comprising: a plurality of adhesive layers laminated and including a first adhesive layer and a second adhesive layer, wherein conductive particles are contained in at least any one of the plurality of adhesive layers, and the DSC exothermic peak temperature of the first adhesive layer is 130° C. or more and 180° C. or less and the DSC exothermic peak temperature of the second adhesive layer is 110° C. or more and 140° C. or less, and the DSC exothermic peak temperature of the second adhesive layer is lower than that of the first adhesive layer by 10° C. or more, and wherein each of the first adhesive layer and the second adhesive layer contains epoxy resin as a thermosetting resin, phenoxy resin as a thermoplastic resin, and a hardening agent, and wherein the first adhesive layer contains spherical inorganic fillers of 70 pts.wt, or more and 170 pts.wt or less, based on a total 100 pts.wt of the thermosetting resin and the thermoplastic resin.
