    Abstract: The present invention relates to a substrate cleaning method and a substrate cleaning apparatus for cleaning a substrate, such as a wafer. The substrate cleaning method includes: holding a periphery of a substrate (W) with holding rollers (6); rotating the substrate (W) about its central axis by rotating the holding rollers (6) about their respective central axes; delivering a two-fluid jet from a two-fluid jet nozzle (2) to a surface of the substrate (W) while moving the two-fluid jet nozzle (2) in a radial direction of the substrate (W), the two-fluid jet (2) being composed of a mixture of a first liquid and a gas; and when the two-fluid jet is being delivered to the surface of the substrate (W), delivering a fan-shaped jet of a second liquid from a spray nozzle (3) to the surface of the substrate (W) to form a flow of the second liquid on the surface of the substrate (W). The fan-shaped jet is located away from the two-fluid jet.

    Abstract: An apparatus and a method which can perform different processes, such as polishing and cleaning, on a surface of a substrate, such as a wafer, with a single processing head, and can process the surface of the substrate efficiently are disclosed. The apparatus includes: a substrate holder configured to hold a substrate and rotate the substrate; and a processing head configured to bring scrubbing tapes into contact with a first surface of the substrate to process the first surface. The processing head includes: pressing members arranged to press the scrubbing tapes against the first surface of the substrate; position switching devices configured to be able to switch positions of the pressing members between processing positions and retreat positions; tape feeding reels configured to feed the scrubbing tapes, respectively; and tape take-up reels configured to take up the scrubbing tapes, respectively.
