Abstract
A tetherless system-in-package includes a first integrated circuit (IC) chip having interconnects and energy harvesting elements. A super-capacitor is configured to store a charge output by the energy harvesting elements. At least a second IC chipset including a smart chip and an optical I/O or an RF I/O is aligned and bonded to at least one of the interconnects of the first IC chip. The first IC chip and the second IC chip are configured to receive a portion of the charge stored by the super-capacitor.
Claims16
A tetherless system-in-package, comprising:
- a first integrated circuit (IC) chip including interconnects and one or more energy harvesting elements;
- a super-capacitor connected to the one or more energy harvesting elements and configured to store a charge output by the energy harvesting elements;
- and
- at least a second IC chip aligned and bonded to at least one of the interconnects of the first IC chip;
- wherein the first IC chip and the second IC chip are configured to receive a portion of the charge stored by the super-capacitor.
A tetherless multichip structure, comprising:
- a primary active integrated circuit (IC) chip having a circuit side surface configured to support at least one secondary IC chip arranged thereon and electrically connected to the primary active IC chip in a planar packaging arrangement without a passive base substrate;
- a primary power source including one or more energy harvesting elements configured to output a charge to power the primary active IC chip and the secondary IC chip;
- and
- a super-capacitor configured to store the charge output of the energy harvesting elements;
- wherein the primary IC chip and the at least one secondary IC chip are configured to receive a portion of the charge stored by the super-capacitor.
