Abstract:
A system and method for blocking heat from reaching an image sensor in a three dimensional stack with a semiconductor device. In an embodiment a heat sink is formed in a back end of line process either on the semiconductor device or else on the image sensor itself when the image sensor is in a backside illuminated configuration. The heat sink may be a grid in either a single layer or in two layers, a zig-zag pattern, or in an interleaved fingers configuration.

Claim (Index 8):
A semiconductor device comprising:\n a first semiconductor substrate having a pixel region; a second semiconductor substrate; a first thermal via and a second thermal via extending though the first semiconductor substrate, wherein the pixel region is interposed between the first thermal via and the second thermal via; and a heat sink between the first semiconductor substrate and the second semiconductor substrate, wherein the heat sink extends from the first thermal via to the second thermal via, and wherein the heat sink thermally couples the first thermal via to the second thermal via.
