Abstract
An anisotropic conductive film includes hard portions at the two edges and a soft portion constituting the remainder. Due to such a construction, when a semiconductor chip is bonded to a substrate by thermocompression, the hard portions inhibit the soft portion from flowing toward the periphery of the semiconductor chip. Thereby, it is possible to prevent the anisotropic conductive film from adhering to a hot pressing tool.
