Abstract:
1. A method of drying a surface of a substrate comprising: a) supporting a substrate; b) rotating the substrate about a rotational center point; c) applying a first liquid to a first surface of the substrate via a liquid dispenser so that a film of the first liquid is formed on the first surface of the substrate; d) applying a first drying fluid to the first surface of the substrate via a first drying fluid dispenser at a location on the substrate that is closer to the rotational center point than a location at which the liquid dispenser applies the first liquid; e) manipulating the first drying fluid dispenser and the liquid dispenser so that the locations at which the first drying fluid and the first liquid are applied to the substrate are both moved in a direction toward an edge region of the substrate, the first drying fluid being applied closer to the rotational center point than the first liquid during the manipulation; and f) upon the first liquid being applied to the edge region of the substrate, discontinuing application of the first liquid while continuing the manipulation of the first drying fluid dispenser.
