  • Publication number: 20110021115
    Abstract: Provided is a substrate polishing apparatus that includes a polishing unit and a pad supporting member. The polishing unit includes a polishing pad polishing a substrate seated on a substrate supporting member, and a pad driving member moving the polishing pad. The pad supporting member is disposed at a side of the substrate supporting member to support a portion of a polishing surface the polishing pad without contacting the substrate when an edge of the substrate seated on the substrate supporting member is polished. Accordingly, the substrate polishing apparatus prevents the polishing pad from being inclined to the outer side of a substrate while an edge of the substrate is polished, thereby improving polishing efficiency and preventing the breakage of a substrate during a polishing process.
