Improved signal path routing in die-to-die bonded circuits

Abstract

A device includes a first die including first integrated circuitry and first conductive wiring layers. The first conductive wiring layers include a power line and a ground line. The device also includes a second die including second integrated circuitry and second conductive wiring layers. The second conductive wiring layers include no power line and no ground line. The first die is aligned with and bonded to the second die. The first conductive wiring layers are electrically connected with the second conductive wiring layers. The second die uses the power line and the ground line of the first die.
