Beschreibung
Zusammenfassung:	A molded semiconductor device comprises a semiconductor chip mounted on an island portion, and external leads coupled with ball pumps on the semiconductor chip by means of a conductive leads patterned on a film carrier, and the conductive leads are formed from a conductive lattice pattern on the film carrier available for other molded devices by selectively cutting the conductive lattice pattern with, for example, a laser beam generator, thereby reducing the production cost.
