Abstract

A semiconductor chip package having a clip type lead frame and fabrication thereof. The package includes a semiconductor chip having a plurality of bond pads thereon, a first package body having a recess, a plurality of inner leads each connected electrically to a corresponding one of the bond pads, a plurality of outleads each extended from a corresponding one of the inner leads for covering along sides of the first package body, and a second package body which covers the semiconductor chip, a plurality of metallic wires and the inner leads. The fabrication method includes the steps of forming a first package body having a recess therein, attaching to the first package body a plurality of inner leads and outleads extended from the inner leads thus to be coveringly exposed on sides of the first package body, attaching in the recess a semiconductor chip having a plurality of bond pads thereon, wire-bonding for electrically connecting each of the inner leads by a metallic wire to a corresponding one of the bond pads provided on the semiconductor chip, and forming a second package body for covering the semiconductor chip, the inner leads and the metallic wires.
