  • 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.
