Patent attributes
A method of drying a surface of a substrate is provided. The method includes supporting and rotating a substrate; applying a liquid to the substrate surface at or near a rotational center point via a liquid dispenser (so that a film of the liquid is formed on the surface); applying a drying fluid to the substrate surface at a predetermined distance from the rotational center point via one or more drying fluid dispensers; and manipulating the drying fluid dispenser(s) so that the location at which the drying fluid is applied to the substrate is moved in a direction toward the rotational center point, while at the same time manipulating the liquid dispenser so that the location at which the liquid is applied to the substrate is moved in a direction outward from the rotational center point. The liquid dispenser and drying fluid dispenser(s) noted above can be located on and/or within an assembly. The assembly can include a first dispenser, a second dispenser, and a third dispenser. The first dispenser supplies liquid while the second and third dispensers supply drying fluid, where the second dispenser has a larger opening than the third dispenser. The second and third dispensers are positioned on the assembly next to one another and spaced from the first dispenser. Further, the second dispenser is located between the third dispenser and the first dispenser, such that the first dispenser is capable of linearly leading the second and third dispensers during movement.
