  • Patent number: 9666540
    Abstract: A semiconductor device is made by mounting a prefabricated heat spreader frame over a temporary substrate. The heat spreader frame includes vertical bodies over a flat plate. A semiconductor die is mounted to the heat spreader frame for thermal dissipation. An encapsulant is deposited around the vertical bodies and semiconductor die while leaving contact pads on the semiconductor die exposed. The encapsulant can be deposited using a wafer level direct/top gate molding process or wafer level film assist molding process. An interconnect structure is formed over the semiconductor die. The interconnect structure includes a first conductive layer formed over the semiconductor die, an insulating layer formed over the first conductive layer, and a second conductive layer formed over the first conductive layer and insulating layer. The temporary substrate is removed, dicing tape is applied to the heat spreader frame, and the semiconductor die is singulated.

  • Patent number: 9142514
    Abstract: In a wafer level chip scale package (WLCSP), a semiconductor die has active circuits and contact pads formed on its active surface. A second semiconductor die is disposed over the first semiconductor die. A first redistribution layer (RDL) electrically connects the first and second semiconductor die. A third semiconductor die is disposed over the second semiconductor die. The second and third semiconductor die are attached with an adhesive. A second RDL electrically connects the first, second, and third semiconductor die. The second RDL can be a bond wire. Passivation layers isolate the RDLs and second and third semiconductor die. A plurality of solder bumps is formed on a surface of the WLCSP. The solder bumps are formed on under bump metallization which electrically connects to the RDLs. The solder bumps electrically connect to the first, second, or third semiconductor die through the first and second RDLs.

  • Patent number: 8890328
    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.
