  • Patent number: 10249580
    Abstract: In conventional device packages, separate standalone inductors are provided and mounted on an interposer substrate along with a die. Separate inductors reduce integration density, decrease flexibility, increase footprint, and generally increase costs. To address such disadvantages, it is proposed to provide a part of an inductor in a substrate below a die. The proposed stacked substrate inductor may include a first inductor in a first substrate, a second inductor in a second a second substrate stacked on the first substrate, and an inductor interconnect coupling the first and second inductors. The core regions of the first and second inductors may overlap with each other at least partially. The proposed stacked substrate inductor may enhance integration density, increase flexibility, decrease footprint, and/or reduce costs.

  • Patent number: 10242957
    Abstract: Ground shielding is achieved by a conductor shield having conductive surfaces that immediately surround individual chips within a multichip module or device, such as a multichip module or device with flip-chip (FC) bumps. Intra-module shielding between individual chips within the multichip module or device is achieved by electromagnetic or radio-signal (RF) isolation provided by the surfaces of the conductor shield immediately surrounding each of the chips. The conductor shield is directly connected to one or more grounded conductor portions of a substrate or interposer to ensure reliable grounding.

  • Patent number: 10154591
    Abstract: Passive device assembly for accurate ground plane control is disclosed. A passive device assembly includes a device substrate conductively coupled to a ground plane separation control substrate. A passive device disposed on a lower surface of the device substrate is separated from an embedded ground plane mounted on a lower surface of the ground plane separation control substrate by a separation distance. The separation distance is accurately controlled to minimize undesirable interference that may occur to the passive device. The separation distance is provided inside the passive device assembly. Conductive mounting pads are disposed on the lower surface of the ground plane separation control substrate to support accurate alignment of the passive device assembly on a circuit board. By providing sufficient separation distance inside the passive device assembly, the passive device assembly can be precisely mounted onto any circuit board regardless of specific design and layout of the circuit board.
