A Wafer Notch Closeup. Silicon wafers are delicate and must be handled with precision during device manufacturing. Flats and notches provide a place for machines to safely grip the wafer without contacting the main surfaces. This protects the valuable wafer surface from any damage or contamination during processing.

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) [37], [38], [39]. 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.
