Abstract
An anisotropic conductive film bonds the semiconductor chip to the substrate while serving as an electrically conductive medium therebetween. The anisotropic conductive film is produced by laminating, in a unitary body, an electrically conductive particle containing layer constructed of a mixture of electrically conductive particles and a resin, and an electrically non-conductive layer having a fluidity lower than the fluidity of the electrically conductive particle containing layer.
