  • Grinding of silicon wafers A review from historical

    Only single-side grinders that grind one side of the wafer can be used for back grinding. Initially used ones are of Blanchard type and creep-feed type (rotary-table vertical-spindle) . Fig. 3 illustrates the Blanchard-type wafer grinder. A rotary table has several chucks aligned along a circle and each chuck holds a silicon wafer.

  • Wafer backgrindingWikipedia

    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
