    摘要: Lead frames for semiconductor chips include spaced apart tie-bars which extend to contact and support the semiconductor chip. Adhesive is used between the tie-bars and the chip to adhesively couple the tie-bars to the chip. The lead frame leads therefore need not be used to adhesively couple the chip to the lead frame, thereby reducing or eliminating the need for equal spacing and close coupling of the leads, and reducing or preventing problems caused by deterioration of adhesive on the leads. The tie-bars may include polyimide tape or liquid adhesive held in cups. During fabrication, a semiconductor chip is mounted on the adhesive material, such that the tie-bars mechanically support the semiconductor chip and the lead ends extend adjacent the semiconductor chip. The lead ends are then electrically connected to the semiconductor chip and the package is encapsulated.

    摘要: 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. Furthermore, the input/output pads can be on an interior portion of the surface of the semiconductor chip, and the insulating layer can have an opening therein for exposing the input/output pads. Accordingly, a dam on the second surface of the insulating layer can be provided around the opening wherein each of the conductive traces extends from adjacent the opening under the dam to a portion of the insulating layer outside the dam. Related methods and assemblies are also discussed.

    摘要: A multi-chip stack package does not include a die pad. The elimination of the die pad provides more room for elements in the package which. Thus, a balanced inner package structure can be achieved, and a poor molding which may expose one of the package elements can be avoided. In the package, an upper chip is bonded to the top surface of a lower chip. To stabilize the chips, auxiliary or inner leads of a lead frame attach to the top surface of a lower chip. This shortens wire lengths between the chips and the inner leads. The shorter wires reduce wire loop heights and thus reduce the probability of exposing wires in a subsequent transfer-molding. A multi-chip stack package which includes an auxiliary lead(s) is also disclosed. The auxiliary leads attach to the top surface of the lower chip and can provide a stable support of a semiconductor chip and prevent the chip from tilting and shifting in transfer-molding. An auxiliary lead can be between the lower and upper chips. The auxiliary leads can also be positioned to prevent undesirable spreading of an adhesive when an upper chip is attached to a lower chip.

    摘要: 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. Solder balls are then attached to the external connections for mounting onto a substrate. This chip-size package is inexpensive to produce, because the first and second lead frames can be produced by a stamping process, which is less complex and cheaper than the conventional half-etching process.

    摘要: A semiconductor device package includes a die pad to which a semiconductor chip is vertically attached, having a smaller horizontal size than a horizontal size of the semiconductor chip. The package includes a plurality of inner leads which are electrically connected to the semiconductor chip, a plurality of outer leads each of which is integral with a respective one of the plurality of inner leads, a tie bar, and a package body for encapsulating the semiconductor chip, the die pad, and the plurality of inner leads. The tie bar for supporting the die pad has a downward bend effecting a downward vertical displacement from the die pad, and has a laterally spaced apart upward bend effecting an upward vertical displacement from the die pad. This package prevents imperfect encapsulation and resulting problems such as cracking of the package, and reduces damage to the die pad, such as warping of the die pad.
