Abstract
Disclosed herein are integrated circuit devices having stacked power supplies and methods of making such integrated circuit devices. In one example, the device includes a first power supply structure, a second power supply structure electrically isolated from the first power supply structure, wherein at least a portion of the second power supply structure is positioned vertically below at least a portion of the first power supply structure, wherein the first power supply structure is one of an interruptible or an uninterruptible power supply structure, while the second power supply structure is the other of the interruptible or the uninterruptible power supply structure, a plurality of constant-power circuits conductively coupled to whichever of the first or second power supply structure that is the uninterruptible power supply and a plurality of interruptible-power circuits conductively coupled to whichever of the first or second power supply structure that is the interruptible power supply.
