Abstract
A spin coating apparatus has a refrigerated container which maintains a coating liquid that contains thermosetting materials or thermal crosslinking agents at a temperature which is sufficiently below the temperature of a substrate on which it is to be coated such that the coating liquid will not set. A heat exchanger heats the coating liquid from the reduced temperature of the refrigerated container to the temperature of the substrate just before the coating liquid is applied to the substrate.
