Abstract:
Provided is a die structure including a die, a bonding structure, and a protection structure. The die includes a substrate and a metal feature disposed over the substrate. The bonding structure is disposed over the die. The bonding structure includes a bonding dielectric layer and a bonding metal layer disposed in the bonding dielectric layer. The bonding metal layer is electrically connected to the metal feature of the die. The protection structure is disposed between a top portion of the bonding metal layer and a top portion of the bonding dielectric layer. A die stack structure and a method of fabricating the die structure are also provided.

Claim (Index 18):
The method of  claim 17 , wherein steps of forming the bonding structure disposed over the die comprises:\n forming a bonding dielectric material over the die; patterning the bonding dielectric material to form an opening in the bonding dielectric material, and the metal feature exposed by the opening; forming a conductive material to fill in the opening, and to cover a top surface of the bonding dielectric material; performing a first planarization process to remove a portion of the conductive material, so as to form the bonding metal layer in the opening, wherein an edge of the top portion of the bonding metal layer is away from sidewalls of the opening; and performing a second planarization process to remover a portion of the bonding dielectric material, so as to form the bonding dielectric layer, wherein an edge of the top portion of the bonding dielectric layer is away from the top portion of the bonding metal layer to form the recess.
