Abstract:
An electronic multi -component package (74, 75) is assembled by placing multiple electronic components (30) within multiple openings (16) of a package substrate (12), then depositing and curing adhesive filler (34) in gaps between the components and the inner peripheries of the openings. Circuit features (38, 42), including conductive interconnects, are formed by thin-film photolithography over both front and back surfaces (22F, 22B) of the package substrate. Preformed conductive vias (18) through the package substrate provide electrical connection between circuit features on opposite substrate surfaces. Additional electronic components (50, 54, 58) may be attached (52, 56, 60) to conductive lands on at least one side of the package. The circuit features also include contact pads (66) for external package connections, such as in a ball-grid-array or equivalent structure.
Abstract:
An integrated circuit assembly comprises an integrated circuit die, and a routable metal layer comprising metal traces linking a plurality of wire bond pads to a plurality of external connection pads such that the metal traces are routable under the die area. An electrically nonconductive adhesive layer couples the integrated circuit die to the routable metal layer, and a plurality of wire bonds link circuitry on the integrated circuit die to the wire bond pads in the routable metal layer. An overfill material encapsulates at least the integrated circuit die and the plurality of wire bonds, and a plurality of solder balls are formed on the plurality of external connection pads.

Abstract:
An apparatus and a method for producing three- dimensional integrated circuit packages. In one embodiment, an electronics package (200) with at least two dice (207, 209) are stacked one atop another is disclosed. A top die (209) is of smaller size compared with a bottom die (207) such that after a die attach operation, wire-bond pads of the bottom die will be exposed for a subsequent wire bonding operation. The bottom die (207) contains contact pads (211) on the front side that couple with one or more passive components (213) fabricated on the back side of the top die (209) to complete the circuit. In another exemplary embodiment, a method to form one or more three-dimensional passive components in a stacked-die package is disclosed wherein partial inductor elements are fabricated on the front side of the bottom die and the back side of the top die. The top and bottom elements are coupled together completing the passive component.
Abstract:
An apparatus and a method for packaging semiconductor devices (205, 207). Disclosed are multi- die packaging apparatuses (200) and techniques, especially useful for integrated circuit dice (207) involving insulative substrates (225), such as silicon- on-insulator (SOI), where grounding of a base layer (225) is not reasonably practical. Disclosed is a means for effectively grounding all layers of an integrated circuit device (205, 207) regardless of whether the device (205, 207) makes direct contact with a die-attach paddle (201).

An apparatus and a method for producing passive components on an integrated circuit device (100). The integrated circuit device (100) has post wafer fabrication integrated passive components (107) situated on the opposite substrate side (105) of the device's integrated circuitry (103). Electrical contact pads (109) of the passive components (107) are configured to be coupled to the electronics package contact pads to complete the electronic package.
Abstract:
An apparatus and a method for packaging semi-conductor devices. The apparatus is applicable to many types of contemporary packaging schemes that utilize a sacrificial metal base strip. Tunnels (213) formed through an encapsulation area (215) surrounding the device (207) and associated bond wires (211) are filled with a metallic conductor by, for example, electroplating, and extend bottom contact pads (205) to an uppermost portion of the encapsulated area (215) . The sacrificial metal base strip (201) serves as a plating bus and is etch-removed after plating. The filled tunnels (213) allow components to be stacked in a three-dimensional configuration.
