    Abstract: A substrate processing method which can clean a peripheral portion of a substrate after polishing and can check the cleaning effect of the peripheral portion of the substrate is disclosed. The substrate processing method includes polishing a peripheral portion of the substrate by pressing a polishing tape having abrasive grains against the peripheral portion of the substrate with a first head, cleaning the peripheral portion of the substrate by supplying a cleaning liquid to the peripheral portion of the substrate after polishing, bringing a tape having no abrasive grains into contact with the peripheral portion of the substrate after cleaning by a second head, applying light to the tape and receiving reflected light from the tape by a sensor, and judging that the peripheral portion of the substrate is contaminated when an intensity of the received reflected light is lower than a predetermined value.
