Connecting structure for an electronic part

Abstract

A connecting structure for an electronic part employs an improved anisotropic electrically conductive layer. The layer includes a hot melt type insulative adhesive, heat resilient particles and carbon particles. Each of the heat resilient particles is made of thermoplastic resin and is plated with metal such as gold, nickel or the like. Each of the carbon particles is melted by a heat pressure and brings about an electric conductivity when it is dried and hardened. Thus, the anisotropically conductive layer disclosed in this invention does not include hard particles at all. Namely, an electronic part such as a solar battery cell or a semiconductor device is not damaged by particles of the conductive layer. In addition, the connecting structure employing the aforementioned layer improves the security of adherence and the reliability of the electric conductivity.
