Wafer backgrinding - Wikipedia
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 μmthick to ensure a minimum of mechanical stability and to avoid warping during high-tem…Wafer Backgrinding Services | Silicon Wafer Thinning Services,Wafer backgrinding, or wafer thinning, is a semiconductor manufacturing process designed to reduce wafer thickness.
