Abstract

Provided are a composition for an anisotropic conductive adhesive, a method of forming a solder bump and a method of forming a flip chip using the same. The composition for an anisotropic conductive adhesive includes a low melting point solder particle and a thermo-curable polymer resin. The anisotropic conductive adhesive includes forming a mixture by mixing a polymer resin and a curing agent, and mixing a deforming agent, a catalyst or a reductant with the mixture.
