A substrate is held by an upper holding device, and a lower-surface center region of the substrate is cleaned. During this cleaning, a suction holder of a lower holding device located below the upper holding device is rotated. The substrate held by the upper holding device is transferred to a suction holder of the lower holding device. A lower-surface outer region of the substrate held by the suction holder is cleaned. After the lower-surface center region of the substrate is cleaned and until the substrate is transferred to the suction holder of the lower holding device, rotation of the lower holding device is stopped. Further, the suction holder is moved in a horizontal direction by a base device. A rotation stopping operation for the suction holder and a horizontal moving operation for the suction holder are performed such that the periods for these operation at least partially overlap with each other.

A substrate processing apparatus includes: a brush processing section configured to perform brush processing on a surface of a substrate taken out from a container; a substrate reversal section configured to flip the substrate before the brush processing and after the brush processing; a substrate imaging section configured to perform pre-processing imaging on the surface before the brush processing, and perform post-processing imaging on the surface after the brush processing and before the substrate is returned to the container; and a controller, wherein the controller determines whether or not the substrate after the brush processing is a good product based on a result of the post-processing imaging, and changes, as necessary, a process condition of the brush processing for the substrate having been subjected to the pre-processing imaging or a substrate to be processed afterward based on at least one of the pre-processing imaging or the post-processing imaging.

A substrate is held by an upper holding device, and a lower-surface center region of the substrate is cleaned with use of a lower-surface brush. The substrate is lowered from an upper holding device and transferred to a suction holder of a lower holding device. The substrate held by the suction holder is cleaned with use of a processing liquid. A cup is provided to be liftable and lowerable between an upper cup position and a lower cup position. The cup is in the lower cup position when waiting. A period for the substrate lowering operation and a period for the cup lifting operation at least partially overlap with each other.
