Abstract
Abstract Warpage in a bonded wafer is limited by maintenance of a stress compensation layer on the backside of the bonded wafer during device fabrication processing. One embodiment applies a sacrificial polysilicon layer over a stress compensation silicon dioxide layer for bonded silicon wafers. The fabrication processing consumes the polysilicon layer but not the stress compensation silicon dioxide.
