A surface mount semiconductor package having a novel lead configuration which facilitates a higher packing density than presently available semiconductor packages. More particularly, the package includes a plurality of electrical leads each having a laterally outwardly extending portion, a downwardly extending portion depending from an inner distal end of the laterally extending portion, and a foot portion extending laterally inwardly from a lower distal end of the downwardly extending portion. A semiconductor chip is mounted, preferably by adhesive means such as insulating tape, to the foot portion of the leads. A plurality of electrical wires are connected between an upper surface of the chip and the laterally outwardly extending portion of respective ones of the leads. A protective body, such as a molded resin body, encapsulates the chip, the wires, the laterally outwardly and downwardly extending portions of the leads. The foot portion of each of the leads is at least partially disposed externally to the molded resin body to facilitate the mounting of the package to a printed circuit board (PCB) or other substrate. |
