    Wafer warping from a grindingbased thinning process is reportedly related to grinding damage and residual stresses. Assuming a uniform layer of grindinginduced damage, Zhou et al. [5] proposed a mathematical model using the Stoney formula, in which wafer warp was a function of damage depth, residual stress and wafer thickness.
