This is an image of a micro-holes array with a scanning range of 30 μm after the Chemical Mechanical Polishing (CMP) process. The CMP process is a key technique for wafer flattening. It can provide a strong guarantee for the improvement of the CMP process in terms of surface roughness and surface shape measurement.
