Patent ID: 8709293

Claim:
A flip-chip mounting resin composition comprising: a resin, metal particles dispersed in the resin, and a convection additive which is contained in the resin and boils upon heating of the resin; wherein said convection additive is at least one material selected from the group consisting of butyl acetate and butyl carbitol, wherein, upon the heating of the resin, said metal particles melt and the boiling convection additive convects within the resin, wherein said resin composition is supplied between substrates which are opposed to each other, each of said substrates having a plurality of electrodes, and upon the heating of said resin composition the metal particles melt so that molten metal particles self-assemble into a region between each electrode of one of said substrates and each electrode of the other of said substrates to form a connection therebetween, and wherein the content of said metal particles contained in said resin ranges from 0.5 to 20% by volume and is defined by the following content percentage: Content percentage of metal particles (% by volume)=[(total surface area of electrodes)/(surface area of substrate×100±10)].
