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 3):
The die stack structure of  claim 2 , wherein the first bonding structure comprises:\n a first bonding dielectric layer, disposed over the first TSV and a back side of the first substrate; and a first bonding metal layer, disposed in the first bonding dielectric layer to be electrically connected with the first TSV and the second bonding structure.
