  • Warping of silicon wafers subjected to back grinding process

    Warping of silicon wafers subjected to back grinding process

    Wafer warping from a grinding based thinning process is reportedly related to grinding damage and residual stresses. Assuming a uniform layer of grinding induced 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.
