  • Patent number: 8222717
    Abstract: An embedded semiconductor die package is made by mounting a frame carrier to a temporary carrier with an adhesive. The frame carrier includes die mounting sites each having a leadframe interconnect structure around a cavity. A semiconductor die is disposed in each cavity. An encapsulant is deposited in the cavity over the die. A package interconnect structure is formed over the leadframe interconnect structure and encapsulant. The package interconnect structure and leadframe interconnect structure are electrically connected to the die. The frame carrier is singulated into individual embedded die packages. The semiconductor die can be vertically stacked or placed side-by-side within the cavity. The embedded die packages can be stacked and electrically interconnected through the leadframe interconnect structure. A semiconductor device can be mounted to the embedded die package and electrically connected to the die through the leadframe interconnect structure.

  • Publication number: 20120104573
    Abstract: A plurality of stacked semiconductor wafers each contain a plurality of semiconductor die. The semiconductor die each have a conductive via formed through the die. A gap is created between the semiconductor die. A conductive material is deposited in a bottom portion of the gap. An insulating material is deposited in the gap and over the semiconductor die. A portion of the insulating material in the gap is removed to form a recess between each semiconductor die extending to the conductive material. A shielding layer is formed over the insulating material and in the recess to contact the conductive material. The shielding layer isolates the semiconductor die from inter-device interference. A substrate is formed as a build-up structure on the semiconductor die adjacent to the conductive material. The conductive material electrically connects to a ground point in the substrate. The gap is singulating to separate the semiconductor die.
