  • Patent number: 9153551
    Abstract: A flip chip packaged component includes a die having a first surface and a dielectric barrier disposed on the first surface of the die. The dielectric barrier at least partially surrounds a designated location on the first surface of the die. A plurality of bumps is disposed on the first surface of the die on an opposite side of the dielectric barrier from the designated location. The flip chip packaged component further includes a substrate having a plurality of bonding pads on a second surface thereof. A cavity is defined by the first surface of the die, the dielectric barrier, and the substrate. A molding compound encapsulates the die and at least a portion of the substrate.
    Type: Grant

  • Publication number: 20080217708
    Abstract: According to an exemplary embodiment, a system-in-package includes at least one semiconductor die situated over a package substrate. The system-in-package further includes a wall structure situated on the at least one semiconductor die. The system-in-package further includes an integrated passive cap situated over the wall structure, where the integrated passive cap includes at least one passive component. The wall structure and the integrated passive cap form an air cavity over the at least one semiconductor die. The system-in-package can further include at least one bond pad situated on a cap substrate. The at least one bond pad on the cap substrate of the integrated passive cap can be electrically connected to a substrate bond pad on the package substrate.
