    Abstract: A semiconductor (30) is shielded from electromagnetic interference by a combination of a reference plane (22) of a circuitized substrate (12) and two different encapsulants. The first encapsulant (38) is an electrically insulative encapsulant which mechanically protects a semiconductor die (32). The first encapsulant is constrained by a dam structure (40) so as not to encapsulate conductive reference pads (18) which are electrically connected to the reference plane by conductive vias (20). A second encapsulant (42) is dispensed over the first encapsulant and is in contact with the reference pads. The second encapsulant is an electrically conductive encapsulant, and is preferably made of a precursor material having the same or similar properties as that of the first encapsulant, but is filled with conductive filler particles to establish electrical conductivity of the encapsulant. Accordingly, the semiconductor die is effectively shielded from both the top and bottom by the electrically conductive encapsulant and the reference plane.

    Abstract: A semiconductor device is disclosed having an electronic component mounted to a mounting surface opposite a heat transfer surface of a die support member. The electronic component includes a plurality of bonding pads each electrically coupled to a plurality of package leads by a number of inner leads. A package body encloses the electronic component, the inner leads, the proximal ends of the package leads and the mounting surface of the die support member. The package body includes an opening exposing a portion of the heat transfer surface of the die support member. An insertable thermally conductive heat sink extends into the opening in the package body making thermal contact with the heat transfer surface of the die support member. A thermally conductive electrically insulating adhesive joins the heat sink to the package body securing the heat sink to the package body. In the assembly process, the package body is formed prior to attachment of the heat sink. During the process of soldering the package leads of the semiconductor device to a mounting substrate, gasses within the package body can escape through the opening before excessive pressure buildup occurs within the package body.

    Abstract: The disclosed invention comprises multiple semiconductor devices within a single carrier structure. In accordance with one embodiment of the invention, a plurality of semiconductor die are coupled to the leads of a leadframe and are encapsulated by individual package bodies. A carrier structure is formed which encircles all of the die and encapsulates portions of the distal ends of the leads. The extreme distal portions of the leads extend through the carrier to form contact points which are used to access the semiconductor die. By having multiple devices within a single carrier, productivity is improved and costs associated with leadframe and carrier structure materials are reduced.

    Abstract: An electronic pad array carrier IC device for mounting on a printed circuit board (PCB) or flex circuit substrate has a thin, flexible "tape" substrate having a plurality of traces. The substrate may be a polyimide or other material that can withstand relatively large lateral mechanical displacement. An integrated circuit die is mounted in proximity with or on the substrate and electrical connections between the integrated circuit chip and the traces are made by any conventional means. The substrate traces are provided at their outer ends with solder balls or pads for making connections to the PCB. A package body covers the die, which body may be optionally used to stand off the package a set distance from the PCB so that the solder balls will form the proper concave structure. Alternatively, a carrier structure may be provided around the periphery of the substrate to add rigidity during handling, testing and mounting, but which may also provide the stand-off function. The thin, flexible substrate can absorb a relatively large lateral or even vertical mechanical displacement over a rather large package area that may accommodate as few as 20 or as many 500 or more connections. The substrate may be optionally transparent or translucent to permit inspection of the bonds after mounting to the PCB. The PCB or flex circuit may also be transparent or translucent for bond inspection purposes. The solder pads or balls may be joined to a via through the substrate at least partially filled with electrically conductive material to permit back side testing of the carrier before or after mounting of the package to the PCB. Additionally, a heat sink structure may be directly bonded to the die in the pad array carrier IC device.

    Abstract: Contaminants are removed from a semiconductor material by heating the semiconductor material to temperature within the range of a minimum temperature where a halogen compound will decompose to halogen atoms without the use of ultraviolet irradiation and react with contaminants present on the semiconductor material and a maximum temperature of 800.degree. C., wherein less than or equal to approximately 50 Angstroms of oxide is formed on the semiconductor material. The ambient in which the semiconductor material is heated is an ambient comprised of a nonreactive gas and a halogen compound for at least a time sufficient to remove a substantial amount of contaminants from the semiconductor material.
