Abstract: A method for three-dimensionally stacking systems on chip with face to face hybrid bonding may include providing a first die including a driver gate driving a first via ladder coupled to a first top metal layer. The method may additionally include providing a second die including a load gate coupled to a second via ladder coupled to a second top metal layer. The method may also include stacking the first die and the second die three-dimensionally using face-to-face hybrid bonds to couple the first top metal layer to the second top metal layer. Various other methods, systems, and computer-readable media are also disclosed.
