  • Publication number: 20120025375
    Abstract: An integrated circuit assembly is fabricated on a metal substrate strip in an array format that has raised circuitry pattern formed by photolithographic and metal etching processes. The circuitry pattern is formed on one side of the metal substrate only. The raised circuitry's etch depth extends partially through the metal substrate. Die attachment can be performed using a non-conductive material applied directly onto and around the raised circuitry features directly under the die. After wirebond and molding processes, the molded metal substrate strip assembly is processed through a metal etching process to remove the metal substrate portion that is exposed beyond the mold cap. A solder mask coating can be applied to protect the metal circuitry and to define the package pad opening to form Land-Grid-Array (LGA) packages. Solder balls can also be attached to form Ball-Grid-Array (BGA) packages.

  • Patent number: 8105880
    Abstract: Methods are disclosed related to attaching a die to a leadframe. One such method includes initially bonding a carrier pad which is pre-coated with a thermosetting first adhesive to the leadframe. The first adhesive can be raised to its thermosetting cure temperature by heating the leadframe to a temperature just above the thermosetting cure temperature of the first adhesive. A thermosetting second adhesive which is liquid at room temperature can be applied to a second major surface of the carrier pad, and the die can be placed on the second adhesive and aligned with the leadframe. The second adhesive can be raised to its thermosetting cure temperature to bond the die to the carrier pad, and in turn form a bonded assembly.

  • Patent number: 8105883
    Abstract: Provided is a method for manufacturing a semiconductor device in which movement of an island in resin sealing is prevented. A molding die includes an upper die and a lower die. The upper and lower dies are fitted together to form cavities and runners. In the lower die, a pod is provided. After heating and melting of a tablet made of a solid resin and housed in the pod, the melted sealing resin is pressurized by a plunger, and is supplied to each of the cavities. Specifically, a liquid sealing resin is supplied from the pod to the cavities, sequentially, from the upstream of the flow of the sealing resin supplied from the pod. The cavities communicate with each other through the runners. Furthermore, the runners through which the cavities communicate are provided to be tilted with respect to a path for supplying the sealing resin.

  • Patent number: 8105881
    Abstract: A method of fabricating a chip package structure includes the steps of providing a lead frame having a die pad, plural leads and at least one structure enhancement element. A chip is then disposed on the die pad and plural bonding wires are formed to electrically connect the chip to the leads. Then, an upper encapsulant and a first lower encapsulant are formed on an upper surface and a lower surface of the lead frame, respectively. The first lower encapsulant has plural concaves to expose the structure enhancement element. Finally, the structure enhancement element is etched with use of the first lower encapsulant as an etching mask until the die pad and one of the leads connected by the structure enhancement element, or two of the adjacent leads connected thereby are electrically insulated.

  • Patent number: 8101470
    Abstract: The present inventions relate to methods and arrangements for using a thin foil to form electrical interconnects in an integrated circuit package. One embodiment of the present invention involves attaching multiple dice to a foil carrier structure. The foil carrier structure is made of a thin foil that is bonded to a carrier. The dice and at least a portion of the metallic foil is then encapsulated with a molding material. The carrier is removed, leaving behind a molded foil structure. The exposed foil is patterned and etched using photolithographic techniques to define multiple device areas in the foil. Each device area includes multiple conductive lines. Afterwards, portions of the conductive lines are covered with a dielectric material and other portions are left exposed to define multiple bond pads in the device area. The molded foil structure can be singulated to form multiple integrated circuit packages.
