  • Patent number: 11121052
    Abstract: A three dimensional integrated circuit (3D-IC) module socket system includes an integrated Fan-Out (InFO) adapter having one or more integrated passive devices (IPDs) embedded in the InFO adapter. The InFO adapter is also integrated into the 3D-IC module socket system by stacking the InFO adapter between a socket and a SoW package. The InFO adapter with embedded IPDs allows for more planar area of the SoW package to be available for interfacing the socket and provides a short distance between the embedded IPDs and computing dies of the SoW package which enhances a power distribution network (PDN) performance and improves current handling of the 3D-IC module socket system.
