Abstract

See full text

A substrate cleaning apparatus performs scrub cleaning of a surface of a substrate with an elongated cylindrical roll cleaning member. The substrate cleaning apparatus includes a roll holder for supporting the cleaning member and rotate the roll cleaning member, a vertical movement mechanism for vertically moving the roll holder so that the roll cleaning member applies a roll load to the substrate at the time of cleaning the substrate by actuation of an actuator having a regulating device, a load cell for measuring the roll load, and a controller for performing feedback control of the roll load through the regulating device based on the measured value of the load cell. The substrate cleaning apparatus further includes a monitor unit for monitoring whether an operation amount of the regulating device falls outside an allowable range of a preset reference value of an operation amount corresponding to a preset roll load.
