ABSTRACT:
A transfer molded semiconductor method arranges a semiconductor chip on a flat die pad so that, at least one predetermined edge surface of the semiconductor chip extends or protrudes over a corresponding edge of the flat die pad. The predetermined edge of the die pad is arranged on the opposite side of a gate beneath a lead frame at the other side. The arrangement suppresses the formation of voids at a side surface of the semiconductor chip, e.g., the side surface opposite the gate at which resin is injected.
