  • Publication number: 20150364387
    Abstract: A wafer polishing method includes first polishing for polishing a wafer backside of a wafer, detecting if a defect exists on the wafer backside, determining whether a level of the detected defect is not within an allowable range, if a defect exists on the wafer backside, and second polishing for repolishing the wafer backside if the level of the defect is within an allowable range. Accordingly, a wafer may be reprocessed so that a level of defects, which may be caused by performing grinding and polishing on the wafer backside, is within an allowable range. Thus, the wafer backside may have uniform quality, and a failure rate of the wafer during a manufacturing processed may be efficiently decreased.
