Abstract
Temperature sensitive devices may be shielded from temperature generating devices on the same integrated circuit by appropriately providing a trench that thermally isolates the heat generating devices from the temperature sensitive devices. In one embodiment, the trench may be formed by a back side etch completely through an integrated circuit wafer. The resulting trench may be filled with a thermally insulating material.
