A substrate processing method includes: performing a both-surface cleaning processing in which a first cleaning body, which ejects the fluid to the one surface or is brought into contact with the one surface, and subsequently moves both the first cleaning body and a second cleaning body, which is in contact with the remaining surface of the upper surface and the lower surface of the substrate and rotated around a first vertical axis, horizontally in synchronization with each other toward an outer peripheral portion of the substrate, and performing a side end cleaning processing in which a third cleaning body is rotated around a second vertical axis and brought into contact with the side end of the substrate to clean the side end of the substrate while simultaneously performing the both-surface cleaning processing.

Substrate processing apparatus and substrate processing method

A substrate processing apparatus includes a substrate holder, a first cleaning body, a first moving mechanism, a second cleaning body, a second moving mechanism, and a controller. The first cleaning body cleans one of the upper surface and the lower surface of the substrate held by the substrate holder by ejecting fluid thereto or by coming into contact therewith. The second cleaning body cleans the other one of the upper surface and the lower surface of the substrate held by the substrate holder by coming into contact therewith. The controller controls the first moving mechanism and the second moving mechanism to perform a both-surface cleaning processing in which the first cleaning body which ejects the fluid to one surface or is in contact with the upper surface and the second cleaning body which is in contact with the lower surface are horizontally moved in synchronization with each other.

A substrate processing apparatus includes: a holder that holds a substrate; a liquid supply that sequentially supplies a first processing liquid and a second processing liquid to a main surface of the substrate held by the holder; a friction body that comes into contact with and rub the main surface of the substrate during the supply of the first processing liquid and the second processing liquid; a mover that moves a contact position of the friction body in a first axial direction and a second axial direction; and a controller that controls the liquid supply and the mover to move the contact position of the friction body in one-side direction of the first axial direction during the supply of the first processing liquid, and move the contact position of the friction body in the other-side direction of the first axial direction during the supply of the second processing liquid.

Contamination of a bottom surface of a substrate caused by a processing liquid used for cleaning a top surface of the substrate can be suppressed. After performing a liquid processing on the top surface of the substrate and a liquid processing on the bottom surface of the substrate in parallel while rotating the substrate by a substrate holding/rotating unit, when stopping the liquid processing on the top surface of the substrate and the liquid processing on the bottom surface of the substrate, a control unitstops a supply of the processing liquid onto the top surface of the substrate by a first processing liquid supply device, and then, stops a supply of the processing liquid onto the bottom surface of the substrate by a second processing liquid supply device
