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.
