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) [37–39]. 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.

TAIKO Process. The TAIKO process is the name of a wafer back grinding process. This method is different to conventional back grinding. When grinding the wafer, the TAIKO process leaves an edge (approximately 3 mm) on the outer most circumference of the wafer and thin grinds only the inner circumference. By using this method, it lowers the risk ...

One of the core factors affecting the shape of the ground wafer is the geometric angle between the grinding wheel and the wafer shaft. Tso and Teng (2001) obtained a wafer with better flatness by adjusting the grinding wheel shaft's angle according to the grinding wafer's surface shape. Sun et al. (2004) established a mathematical model for the dressing shape of chuck and the wafer thickness.

Wafer lapping is a global planarization process that improves wafer flatness by removing surface damage, often from backside grinding. It is most common on silicon wafers, although certain applications require gallium arsenide (GaAs) and indium phosphide (InP) wafers to undergo this process as well.
