Abstract:
A method of manufacturing semiconductor devices, comprising:preparing a common substrate comprising a plurality of unit portions, such that each unit portion includes an island portion and lead terminals separated from said island portion, and such that the lead terminals of each one of said unit portions are continuous with the island portion of an adjacent unit portion; mounting a semiconductor chip on the island portion of each one of said unit portions, and connecting wires between the semiconductor chip and the lead terminals of each of said unit portions; disposing a dam on a periphery of said common substrate surrounding said plurality of unit portions; supplying resin material onto a surface of said common substrate inside of said dam so as to form a resin body covering all over the semiconductor chips and the wires; leveling said resin body to form a flat surface thereof and such that said resin body remains covering said semiconductor chips and said wires; and cutting said common substrate and said resin body along edges of said unit portions in such a manner as to divide each of said island portions from the lead terminals that are continuous therewith, so as to separate said unit portions to thereby form a plurality of semiconductor devices.
