The depth of these scratches will depend on the size of grit of the wheel and the amount of vertical pressure applied during grinding. (A finer grit results in smaller and shallower scratches.) Because the strength of the silicon is inversely proportional to the depth of the scratches, it is important to minimize the roughness of the wafer surface.
