Abstract: A package for a semiconductor chip including a plurality of input/output pads includes an insulating layer and a plurality of conductive traces. The insulating layer has a first surface for bonding with the surface of the semiconductor chip so that the input/output pads are exposed adjacent the insulating layer. The conductive traces are provided on a second surface of the insulating layer opposite the first surface wherein each of the conductive traces corresponds to a respective one of the input/output pads. In particular, the conductive traces are adapted to receive a plurality of bonding wires each of which corresponds to a respective one of the input/output pads. Accordingly, each of the bonding wires can be bonded at a first end to the respective input/output pad and at a second end to the respective conductive trace.

Abstract: A method for manufacturing a known good die array("KGD" array ), which includes the steps of: (a) forming a plurality of circuit patterns, and bonding pads to match solder bumps on a wafer; (b) providing solder bumps on the bonding pads; (c) forming metal layers for wire-bonding on the solder bumps; (d) dividing the wafer having metal layers into respective individual circuit pattern unit dies; (e) holding at least one die in a die holder for testing; (f) wire-bonding circuit contacts of the die holder with the metal layers using wires; (g) testing the die which is electrically interconnected with the die holder; and (h) removing simultaneously the metal layer on the solder bumps for wire bonding and the wires from the die to give a known good die array having solder bumps.

Abstract: A semiconductor device package contains column leads which are electrically connected to a chip. The column leads, chip and electrical connection means are encapsulated to form a package body, from which the column leads extend for connection to a substrate such as a printed circuit board. A lead frame for the column leads can be formed by etching the column leads and a die pad out of a section of column lead material with a polyimide layer backing. Alternatively, a lead frame having parallel side rails on either side of a die pad can be used as an assembly frame for rows of column leads. Mass production of this package body using either type of lead frame produces high reliability packages in a simple and cost-effective way.

Abstract: A method for manufacturing a chip-size package and the chip-size package produced by the method uses first and second lead frames which are prepared by a stamping process. The first lead frame has leads with receiving parts, and the leads are integrally formed with lengthwise side rails of the lead frame. The second lead frame has external connections which align with the receiving parts of the leads when the second lead frame is positioned on top of the first lead frame and attached thereto. Guide holes located on the crosswise side rails of both lead frames can be used to easily align the two lead frames. A semiconductor chip is then adhered to the underside of the first lead frame, and the bonding pads of the semiconductor chip are electrically connected to the leads of the first lead frame. Then the two lead frames and the chip are encapsulated, with only the external connections of the second lead frame remaining exposed to the outside.

Abstract: A stacked semiconductor package including a plurality of semiconductor devices stacked over one another and having outer leads, which are extended from sides of the devices and bent downwardly. A plurality of supports are vertically interposed between the outer leads. The supports electrically connect the outer leads in vertical direction only.
