  • Publication number: 20170148721
    Abstract: A semiconductor device has a semiconductor die mounted to a carrier. An encapsulant is deposited over the semiconductor die and carrier. The carrier is removed. A first insulating layer is formed over a portion of the encapsulant within an interconnect site outside a footprint of the semiconductor die. An opening is formed through the first insulating layer within the interconnect site to expose the encapsulant. The opening can be ring-shaped or vias around the interconnect site and within a central region of the interconnect site to expose the encapsulant. A first conductive layer is formed over the first insulating layer to follow a contour of the first insulating layer. A second conductive layer is formed over the first conductive layer and exposed encapsulant. A second insulating layer is formed over the second conductive layer. A bump is formed over the second conductive layer in the interconnect site.

  • Patent number: 9653445
    Abstract: A method of making a semiconductor device comprises the steps of providing a first manufacturing line, providing a second manufacturing line, and forming a first redistribution interconnect structure using the first manufacturing line while simultaneously forming a second redistribution interconnect structure using the second manufacturing line. The method further includes the steps of testing a first unit of the first redistribution interconnect structure to determine a first known good unit (KGU), disposing a known good semiconductor die (KGD) over the first KGU of the first redistribution interconnect structure, testing a unit of the second redistribution interconnect structure to determine a second known good unit (KGU, and disposing the second KGU of the second redistribution interconnect structure over the first KGU of the first redistribution interconnect structure and the KGD. A resolution of the second manufacturing line is greater than a resolution of the first manufacturing line.

  • Publication number: 20170133270
    Abstract: A semiconductor device has a carrier with a fixed size. A plurality of first semiconductor die is singulated from a first semiconductor wafer. The first semiconductor die are disposed over the carrier. The number of first semiconductor die on the carrier is independent from the size and number of first semiconductor die singulated from the first semiconductor wafer. An encapsulant is deposited over and around the first semiconductor die and carrier to form a reconstituted panel. An interconnect structure is formed over the reconstituted panel while leaving the encapsulant devoid of the interconnect structure. The reconstituted panel is singulated through the encapsulant. The first semiconductor die are removed from the carrier. A second semiconductor die with a size different from the size of the first semiconductor die is disposed over the carrier. The fixed size of the carrier is independent of a size of the second semiconductor die.

  • Publication number: 20170133330
    Abstract: A semiconductor device has a substrate with a stiffening layer disposed over the substrate. The substrate has a circular shape or rectangular shape. A plurality of semiconductor die is disposed over a portion of the substrate while leaving an open area of the substrate devoid of the semiconductor die. The open area of the substrate devoid of the semiconductor die includes a central area or interstitial locations among the semiconductor die. The semiconductor die are disposed around a perimeter of the substrate. An encapsulant is deposited over the semiconductor die and substrate. The substrate is removed and an interconnect structure is formed over the semiconductor die. By leaving the predetermined areas of the substrate devoid of semiconductor die, the warping effect of any mismatch between the CTE of the semiconductor die and the CTE of the encapsulant on the reconstituted wafer after removal of the substrate is reduced.

  • Patent number: 9620455
    Abstract: A semiconductor wafer contains a plurality of semiconductor die with bumps formed over contact pads on an active surface of the semiconductor die. An ACF is deposited over the bumps and active surface of the wafer. An insulating layer can be formed between the ACF and semiconductor die. The semiconductor wafer is singulated to separate the die. The semiconductor die is mounted to a temporary carrier with the ACF oriented to the carrier. The semiconductor die is forced against the carrier to compress the ACF under the bumps and form a low resistance electrical interconnect to the bumps. An encapsulant is deposited over the semiconductor die and carrier. The carrier is removed. An interconnect structure is formed over the semiconductor die and encapsulant. The interconnect structure is electrically connected through the compressed ACF to the bumps. The ACF reduces shifting of the semiconductor die during encapsulation.
