Abstract:
Provided is a die stack structure including a first die, a second die, a first bonding structure, and a second bonding structure. The first bonding structure is disposed on a back side of the first die. The second bonding structure is disposed on a front side of the second die. The first die and the second die are bonded together via the first bonding structure and the second bonding structure and a bondable topography variation of a surface of the first bonding structure bonding with the second bonding structure is less than less than 1 μm per 1 mm range. A method of manufacturing the die stack structure is also provided.

Claim (Index 11):
A method of fabricating a die stack structure, comprising:\n providing a first die having at least one first through-substrate via (TSV) therein; performing a thinning process on a back side of the first die to expose the first TSV; forming a first bonding structure over the back side of the first die after the thinning process; forming a second bonding structure over a front side of a second die; and bonding the first die and the second die together via the first bonding structure and the second bonding structure.
