  • Patent number: 9768080
    Abstract: A semiconductor manufacturing method includes several operations. One operation is catching an image of a predetermined location on a surface of a pad installed in a chemical mechanical polishing (CMP) apparatus by a surface detector. One operation is transferring the image of the predetermined location to a processor. One operation is calculating a surface roughness value of the predetermined location from the image. One operation is comparing the surface roughness value with a threshold value by the processor to determine if the surface roughness condition at the predetermined location is smaller than the threshold value, and the surface is configured for polishing a to-be-polished surface of a wafer.
