  • Patent number: 8648448
    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.
