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.
