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 9):
A method comprising:\n attaching a die stack to an interposer; encapsulating the die stack with an encapsulant; planarizing the encapsulant, top surfaces of the encapsulant and the die stack being level after the planarizing the encapsulant; forming a recess in a topmost integrated circuit die of the die stack, the topmost integrated circuit die comprising a substrate having an active surface and a back surface, the substrate having a first height, the recess extending a first depth from the back surface of the substrate, the first depth being less than the first height; filling the recess with a first conductive material to form a dummy through substrate via (TSV); forming a dummy connector on the dummy TSV; dispensing a thermal interface material on the topmost integrated circuit die, the thermal interface material surrounding the dummy connector; and attaching a heat spreader to the topmost integrated circuit die, the heat spreader covering and surrounding the die stack and the interposer.
