Abstract:
1. A frame from which individual semiconductor packages are formed comprising an array of lead frames, each said lead frame including a die pad and a semiconductor device which is at least partially encapsulated in molding compound and mounted on said die pad, longitudinally and transversely oriented metal leads disposed in a grid formation and interconnecting the lead frames to one another, said longitudinal and transverse leads defining boundaries between the respective lead frames whereby cutting along predetermined longitudinal and transverse cut lines disposed adjacent the respective longitudinal and transverse leads results in individual semiconductor packages, each said lead frame having suspending leads which support the respective die pad and each suspending lead having an outer end with a generally forked-shaped configuration defined by a pair of spaced-apart legs, wherein a plurality of said lead frames are directly connected to one another and define an area therebetween which is bordered by said forked-shaped ends of said directly connected lead frames, and one of said longitudinal lead and said transverse lead is eliminated within each of said areas such that said areas are void of metal and no metal pieces are left at the corners of the individual semiconductor packages formed after cutting along the longitudinal and transverse cut lines.
