  • Patent number: 8105915
    Abstract: A semiconductor device is made by forming a first conductive layer over a first temporary carrier having rounded indentations. The first conductive layer has a non-linear portion due to the rounded indentations. A bump is formed over the non-linear portion of the first conductive layer. A semiconductor die is mounted over the carrier. A second conductive layer is formed over a second temporary carrier having rounded indentations. The second conductive layer has a non-linear portion due to the rounded indentations. The second carrier is mounted over the bump. An encapsulant is deposited between the first and second temporary carriers around the first semiconductor die. The first and second carriers are removed to leave the first and second conductive layers. A conductive via is formed through the first conductive layer and encapsulant to electrically connect to a contact pad on the first semiconductor die.

  • Patent number: 8105872
    Abstract: A semiconductor device has a plurality of semiconductor die mounted to a temporary carrier. A prefabricated shielding frame has a plate and integrated bodies extending from the plate. The bodies define a plurality of cavities in the shielding frame. A penetrable material is deposited in the cavities of the shielding frame. The shielding frame is mounted over the semiconductor die such that the penetrable material encapsulates the die. The carrier is removed. An interconnect structure is formed over the die, shielding frame, and penetrable material. The bodies of the shielding frame are electrically connected through the interconnect structure to a ground point. The shielding frame is singulated through the bodies or through the plate and penetrable material to separate the die. TIM is formed over the die adjacent to the plate of the shielding frame. A heat sink is mounted over the plate of the shielding frame.

  • Patent number: 8101460
    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.

  • Patent number: 8097489
    Abstract: A semiconductor device includes a pre-fabricated shielding frame mounted over a sacrificial substrate and semiconductor die. An encapsulant is deposited through an opening in the shielding frame around the semiconductor die. A first portion of the shielding frame to expose the encapsulant. Removing the first portion also leaves a second portion of the shielding frame over the semiconductor die as shielding from interference. A third portion of the shielding frame around the semiconductor die provides a conductive pillar. A first interconnect structure is formed over a first side of the encapsulant, shielding frame, and semiconductor die. The sacrificial substrate is removed. A second interconnect structure over the semiconductor die and a second side of the encapsulant. The shielding frame can be connected to low-impedance ground point through the interconnect structures or TSV in the semiconductor die to isolate the die from EMI and RFI, and other inter-device interference.

  • Patent number: 8097943
    Abstract: A semiconductor die has active circuits formed on its active surface. Contact pads are formed on the active surface of the semiconductor die and coupled to the active circuits. A die extension region is formed around a periphery of the semiconductor die. Conductive through hole vias (THV) are formed in the die extension region. A wafer level conductive plane or ring is formed on a center area of the active surface. The conductive plane or ring is connected to a first contact pad to provide a first power supply potential to the active circuits, and is electrically connected to a first conductive THV. A conductive ring is formed partially around a perimeter of the conductive plane or ring and connected to a second contact pad for providing a second power supply potential to the active circuits. The conductive ring is electrically connected to a second THV.
