 · Grinding wheels : In general, grinding typically involves Z1 Z2 grinding wheels where Z1 is coarse grinding ( < #500 grit grinding wheel) and removes most of the Silicon (~ 500 – 600um). Z2 grinding is a fine grinding process ( typically < #3000 grit grinding wheel, but can be little finer) and removes about 2050um of Silicon.

 · A systematic investigation on the effects of wafer thinning process on the surface roughness, morphology and fracture strength of silicon chips was conducted. The results of the study suggest that the fracture strength of the silicon chips was determined predominantly by the geometry and scratch tip sharpness of a few large and deep scratches formed during wafer thinning.
