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 15):
A semiconductor device comprising:\n an image sensor die having a first surface and a second surface, the second surface being opposite the first surface; an processing die having a third surface and a fourth surface, the fourth surface being opposite the third surface, the second surface being in physical contact with the third surface; a thermal via extending from the first surface of the image sensor die toward the second surface of the image sensor die; and a heat sink in thermal contact with the thermal via, wherein the heat sink is interposed between the first surface of the image sensor die and the fourth surface of the processing die, and wherein a width of the heat sink is less than a width of the image sensor die.
