A stacking structure including a first die, a second die stacked on the first die, and a filling material is provided. The first die has a first bonding structure, and the first bonding structure includes first bonding pads and a first heat dissipating element. The second die has a second bonding structure, and the second bonding structure includes second bonding pads and a second heat dissipating element. The first bonding pads are bonded with the second bonding pads. The first heat dissipating element is connected to one first bonding pad of the first bonding pads and the second heat dissipating element is connected to one second bonding pad of the second bonding pads. The filling material is disposed over the first die and laterally around the second die. The first and second dies are bonded through the first and second bonding structures.
