ABSTRACT:
A method includes a resin sealing step of placing, in a cavity28of a mold20, a substrate16to which semiconductor elements11on which bumps12are arranged, a resin sealing step of supplying resin35to positions of the bumps12so that a resin layer13sealing the bumps12is formed, a protruding electrode exposing step of exposing at least ends of the bumps12sealed by the resin layer13so that ends of the bumps12are exposed from the resin layer13, and a separating step of cutting the substrate16together with the resin layer13so that the semiconductor elements11are separated from each other.
