Abstract: Microelectronic modules are described. In an embodiment, a microelectronic module includes a module substrate, a chip mounted onto the module substrate, and a semiconductor-based integrated passive device between the chip and the module substrate. The semiconductor-based integrated passive device may include an upper RDL stack-up with thicker wiring layers than a lower BEOL stack-up. The semiconductor-based integrated passive device may be further solder bonded or hybrid bonded with the chip.

Abstract: A power delivery sub-system included in a computer system employs a primary voltage regulator circuit that generates a primary supply voltage on a primary power supply node. The power delivery sub-system also includes multiple bypass voltage regulator circuits that source corresponding bypass currents to a local power supply nodes in an integrated circuit. The integrated circuit includes multiple circuit blocks coupled to corresponding ones of the local power supply nodes, and multiple local voltage regulator circuits coupled to the primary power supply node. When a voltage level of a given local power supply node drops below a threshold value, a corresponding local voltage regulator circuit sources a supply current to the given local power supply node.

Abstract: Integrated passive devices (IPDs), electronic packaging structures, and methods of testing IPDs are described. In an embodiment, an electronic package structure includes an IPD with an array of capacitor banks that are electrically separate in the IPD, and a package routing that includes an interconnect electrically connected to an IC and a plurality of the capacitor banks in parallel.
