Patent ID: 8736039

Claim:
A stacked structure, comprising: a first die having a first die area defined over a first surface, the first die area having a first edge extending in a first direction and disposed between adjacent second and third edges extending in a second direction, at least one first protective structure formed over the first surface and around the first die area, at least one side of the first protective structure having at least one first extension part coupled to the first protective structure and extending away from the first edge of the first die area and across a first scribe line disposed adjacent to the at least one first protective structure such that the first extension part is coupled to a third protective structure disposed adjacent to and surrounding a third die, the first extension part disposed between an axis defined by the second edge and an axis defined by the third edge; and a second die bonded over the first die, the second die having a second die area defined over a second surface, the second die area having a fourth edge extending in the first direction and disposed between adjacent fifth and sixth edges extending in the second direction, at least one second protective structure formed over the second surface and around the second die area, at least one side of the second protective structure having at least one second extension part coupled to the second protective structure and extending away from the fourth edge of the second die area and across a second scribe line disposed adjacent to the at least one second protective structure such that the second extension part is coupled to a fourth protective structure disposed adjacent to and surrounding a fourth die, the at least one second extension part disposed between an axis defined by the fifth edge and an axis defined by the sixth edge, wherein the first extension part is connected with the second extension part.
