Fine grinding of silicon wafers refers to the grinding operations with #2000 mesh (3∼6 μm grit size) or finer diamond wheels. The wafer surfaces to be fine-ground generally have no damage or very little damage and the …

Laser grinding reduced the surface roughness of single-crystal silicon wafer by over 81%, when measured at the mm scale, but achieved a roughness level of only Ra = 75 nm when measured at the micro-scale. Meanwhile, the laser-grinded surface changes were smother because laser grinding removes abundant peaks.
