  • Publication number: 20230360994
    Abstract: A multi-chip unit suitable for chip-level packaging may include multiple IC chips that are interconnected through a metal redistribution structure, and that are directly bonded to an integrated heat spreader. Bonding of the integrated heat spreader to the multiple IC chips may be direct so that no thermal interface material (TIM) is needed, resulting in a reduced bond line thickness (BLT) and lower thermal resistance. The integrated heat spreader may further serve as a structural member of the multi-chip unit, allowing a second side of the redistribution structure to be further interconnected to a host by solder interconnects. The redistribution structure may be fabricated on a sacrificial interposer that may facilitate planarizing IC chips of differing thickness prior to bonding the heat spreader. The sacrificial interposer may be removed to expose the RDL for further interconnection to a substrate without the use of through-substrate vias.

  • Patent number: 11527489
    Abstract: An apparatus includes a substrate, one or more integrated circuit dies on the substrate, and a stiffener affixed to the substrate. One or more sections of the stiffener may includes a magnetic material. The apparatus further includes an inductive circuit element comprising one or more conductive structures wrapped around the magnetic material. In some examples where a first coil is wrapped around a first section of the stiffener, and a second coil is wrapped around a second section of the stiffener, current supplied to the first coil generates at the second coil a current that is further transmitted to the one or more semiconductor dies.
