  • Publication number: 20080125019
    Abstract: The present invention provides a polishing pad, which has a flatness area and an emboss area on its polishing surface, wherein the flatness area is a flat surface with a roughness less than 20 ?m, for polishing a wafer; the emboss area has grooves, holes or a combination thereof, for pulling up a wafer from the polishing surface after polishing. By using the polishing pad according to the invention, a wafer may have a higher surface flatness after Chemical-Mechanical Polishing (CMP); and after polishing, the wafer is moved to the emboss area of the polishing pad, so that the wafer may be easily separated from the polishing pad surface.
