Claims
- 1. A method of manufacturing a semiconductor device, comprising the steps of:
(a) providing a semiconductor chip and a lead frame, said semiconductor chip having bonding pads formed on a main surface thereof and a rear surface opposite to said main surface, said lead frame having a die pad, supporting leads continuously formed with said die pad and a plurality of leads each having an inner lead portion and an outer lead portion continuously formed with said inner lead portion, tips of said inner lead portions of said plurality of leads being disposed to surround said die pad in a plane view, said die pad having a size which is smaller than that of said semiconductor chip; (b) mounting said semiconductor chip on said die pad, such that said semiconductor chip is bonded to said die pad and said tips of said inner lead portions of said plurality of leads are disposed to surround said semiconductor chip; (c) electrically connecting said tips of said inner lead portions of said plurality of leads with said bonding pads of said semiconductor chip by a plurality of bonding wires respectively; (d) disposing said lead frame with said semiconductor chip in a mold die having an upper die and a lower die in such a manner that said semiconductor chip, said plurality of bonding wires and said die pad are disposed in a cavity defined by said upper and lower dies of said mold die at a boundary between said inner lead portion and said outer lead portion of each of said plurality of leads; (e) injecting a resin into said cavity of said mold die by a transfer molding, thereby forming a resin member sealing said semiconductor chip, said plurality of bonding wires, said inner lead portions of said plurality of leads and said die pad by said resin member.
- 2. Product formed by the method of claim 1.
