  • Publication number: 20090056765
    Abstract: Provided is a single type substrate treating apparatus and a cleaning method the substrate treating apparatus. A cleaning process is periodically performed on a substrate support member after a series of repeated substrate treating processes is performed to remove contaminants remaining on the substrate support member and minimize thermal deformation of the substrate support member due to a high temperature chemical solution.
