Abstract
The present invention relates to a substrate processing apparatus and a substrate processing method suitable for processing a substrate with a plurality of liquids. A substrate processing apparatus comprises a substrate holding device for holding a substrate, a container having an opening portion disposed so that the opening portion is opposed to a surface, to be processed, of the substrate, a driving device for moving the container or the substrate holding device between a position at which the container approaches the substrate or a position at which the substrate enters the container, and a position at which the container is positioned away from the substrate, a first treatment liquid supply device for bringing the surface, to be processed, of the substrate which has approached or entered the container into a first treatment liquid, a covering member for covering the opening portion of the container at the position at which the container is positioned away from the substrate, and a second treatment liquid supply device for bringing the surface, to be processed, of the substrate into a second treatment liquid in a state in which the opening portion of the container is covered wit…
