Abstract

See full text

A substrate processing apparatus includes a substrate rotator, a processing liquid supply, an anode and a cathode, and a controller. The substrate rotator is configured to hold and rotate a substrate. The processing liquid supply is configured to supply a processing liquid to the substrate held by the substrate rotator. The anode and the cathode are configured to apply a voltage to the processing liquid supplied from the processing liquid supply. The controller is configured to control the substrate rotator, the processing liquid supply, and the anode and the cathode. The controller allows, by contacting the anode and the cathode with the processing liquid independently, the processing liquid in contact with the anode and the processing liquid in contact with the cathode to be supplied to the substrate while being spaced apart from each other when the substrate is rotated.
