Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and high-density packaging of integrated circuits (IC). ICs are produced on semiconductor wafers that undergo a multitude of processing steps. The silicon wafers predominantly used today have diameters of 200 and 300 mm. They are roughly 750 μm thick to ensure a minimum of mechanical stability and to avoid warping during high-tem… WebGlobal flatness (variations relative to a whole-wafer plane) can be an issue in CMP process development and control since these processes often thin the edge of a wafer more than the center. Global flatness metrics defined for silicon wafers include: GFLR (Global flatness–Front surface–Least squares reference plane–Range)
