Abstract
A device package includes a first die directly bonded to a second die at an interface, wherein the interface comprises a metal-to-metal bond and a heat dissipation feature over the first die. The heat dissipation feature includes a thermal base over the first die and surrounding the second die, wherein the thermal base is made of a metal; and a plurality of thermal vias on the thermal base; and an encapsulant over first die and surrounding the second die, surrounding the thermal base, and surrounding the plurality of thermal vias.
