Abstract:
Provided is a three-dimensional integrated circuit (3DIC) structure including a die stack structure, a metal circuit structure, and a protective structure. The die stack structure includes a first die and a second die face-to-face bonded together. The metal circuit structure is disposed over a back side of the second die. The protective structure is disposed within the back side of the second die and separates one of a plurality of through-substrate vias (TSVs) of the second die from the metal circuit structure.

Claim (Index 12):
A method of manufacturing a 3DIC structure, comprising:\n forming a die stack structure comprising a first die and a second die face-to-face bonded together; performing a first planarization process to expose a plurality of through-substrate vias (TSVs) of the second die at a back side of the second die, wherein the back side of the second die has a first recess that extends into one of the plurality of TSVs of the second die; filling a protective structure in the first recess with a conformal layer; and forming a metal circuit structure over the back side of the second die to electrically connected to the die stack structure through another of the plurality of TSVs, wherein the protective structure electrically isolates the one of the plurality of TSVs of the second die from the metal circuit structure.
