Abstract:
In an embodiment, a device includes: a die stack over and electrically connected to an interposer, the die stack including a topmost integrated circuit die including: a substrate having a front side and a back side opposite the front side, the front side of the substrate including an active surface; a dummy through substrate via (TSV) extending from the back side of the substrate at least partially into the substrate, the dummy TSV electrically isolated from the active surface; a thermal interface material over the topmost integrated circuit die; and a dummy connector in the thermal interface material, the thermal interface material surrounding the dummy connector, the dummy connector electrically isolated from the active surface of the topmost integrated circuit die.

Claim (Index 23):
A method comprising:\n attaching a die stack to an interposer, the die stack comprising active devices, the interposer comprising interconnect structures, the interconnect structures of the interposer being electrically coupled to the active devices of the die stack after the attaching the die stack to the interposer; forming a dummy through substrate via (TSV) in the die stack, the dummy TSV being electrically isolated from the active devices of the die stack and the interconnect structures of the interposer; forming a conductive feature on the dummy TSV; dispensing a thermal interface material around the conductive feature; and attaching a heat spreader to the die stack with the thermal interface material, the thermal interface material and the conductive feature thermally coupling the heat spreader to the dummy TSV.
