Semiconductor device and a method of manufacturing the same
Means for forming a package is disclosed on which is mounted a semiconductor chip with a high-speed LSI formed thereon, using a wire bonding method. The package comprises a semiconductor chip, a die pad smaller than a main surface of the semiconductor chip, a sealing member, plural leads each comprising an outer terminal portion and an inner lead portion, and plural bonding wires for connection between bonding pads formed on the semiconductor chip and the inner lead portions of the leads, each of the inner lead portions being bent in a direction away from a mounting surface of the sealing member, thereby approximating the height of the chip-side bonding pads and that of a bonding position of the inner lead portions to each other, whereby the wire length can be made shorter and it is possible to suppress an increase in inductance of the wire portions and attain impedance matching at various portion of a high-frequency signal input/output transmission path.
