Abstract:
1. A chip assembly comprising: a substrate having a top surface and a bottom surface; a first die having a circuit surface and a connecting surface, the circuit surface comprising one or more integrated circuits; a chip-scale frame having an inside surface, an outside surface, and a well region, the well region having an opening within the inside surface, the well region having a wall, the well region housing the first die, the first die attached to the wall by a first coupling mechanism, the inside surface coupled to the top surface of the substrate by a second coupling mechanism; a heat sink coupled to the outside surface of the chip-scale frame using a third coupling mechanism; and a second die having a second circuit surface and a second connecting surface, the second circuit surface comprising one or more integrated circuits, contacts on the second circuit surface coupled to contacts on the top surface of the substrate for electrical communication, a circuit on the second die coupled to a circuit on the first die for electrical communication via connectors embedded in the substrate and via connectors embedded in the chip-scale frame, the second connecting surface attached to the heat sink for at least thermal conduction, the second die disposed between the heat sink and the substrate, wherein the first die and the chip-scale frame are disposed laterally adjacent to the second die, the first die is disposed between the chip-scale frame and the substrate, the chip-scale frame is disposed between the heat sink and the substrate, the circuit surface faces toward the substrate, the connecting surface faces toward the heat sink, contacts on the circuit surface are coupled to contacts on the wall using wire bonds, and the connecting surface is attached to the wall using an adhesive, wherein the second coupling mechanism comprises solder joints for electrical communication, and the third coupling mechanism comprises an adhesive that is at least thermally conductive.
