Abstract

A method of producing a cavity package semiconductor device is disclosed. The method includes providing a bar pad having a plurality of bar pad straps, each strap extending outwardly from the outer edge of the bar pad and spaced about the edge of the bar pad; mounting integrated circuits having bond pads on the bar pad; molding a packing material onto a central portion of lead fingers and the bar straps to grip and surround each lead finger with package material, with a portion of each lead finger extending externally from the ring at both the exterior and interior thereof and to secure the bar pad straps therein; electrically coupling the bond pads to the portion of desired ones of the lead fingers extending toward the interior of the ring; and enclosing both ends of the ring to provide a cavity in the ring to suspend a bar pad with the integrated circuit thereon within the cavity with the bar pad straps.
