    Abstract: A substrate processing method capable of preventing an adherence of a foreign matter to a substrate is disclosed. The substrate processing method comprises: a substrate rotating step of rotating a substrate W while holding the substrate W; a first-liquid upper supply step of supplying a first liquid onto an upper surface of the substrate W while rotating the substrate W; a polishing step of pressing a polishing tape 23 to the substrate W while supplying the first liquid in a state of rotating the substrate W; a second-liquid upper supply step of supplying a second liquid onto the upper surface of the substrate W while rotating the substrate W; and a cleaning step of pressing a cleaning tape 29 to the substrate W while supplying the second liquid in a state of rotating the substrate W and terminating after the polishing step is terminated. The second liquid is either of a conducting water, a surfactant solution, or ozone water.

    Abstract: A polishing apparatus capable of accurately detecting a polishing end point of a periphery of a substrate, such as a wafer, is disclosed. The polishing apparatus includes a polishing head configured to press a polishing tool against the periphery of the substrate on a substrate holding surface. The polishing head includes a pressing member configured to press the polishing tool against the periphery of the substrate, and a shear-force detection sensor configured to detect a shear force acting on the pressing member and output an index value indicating a magnitude of the shear force. An operation controller has a memory storing a program configured to determine a polishing end point at which the index value reaches a threshold value, and a processer configured to execute the program.

    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.
