Abstract:
A semiconductor device manufacturing method comprising the steps of:providing a substrate having adjoining multiple chip mounting areas on a mounting surface; mounting multiple semiconductor chips having functional and non-functional surfaces on said mounting areas on said substrate such that the functional surfaces of said chips face said mounting surface of said substrate; sealing said multiple chips to said mounting surface of said substrate with molding resin; cutting through said substrate from a surface of said substrate opposite said mounting surface into said molding resin to a depth of 30% or less of the depth of said molding resin to form recesses between said chip mounting areas on said substrate; removing portions of said molding resin and said multiple chips from said mounting surface of said substrate to reach said recesses, thereby separating said multiple chip mounting areas of said substrate to form individual semiconductor devices, each of which contains one or more of said multiple semiconductor chips.
