Abstract
In coating a substrate such as a glass plate with a photo-sensitive coating solution by spin coating, the substrate is tilted so that the coating solution flows down the substrate to cover the entire surface of the latter, and then the substrate is held horizontal, and rotated so that a layer of coating solution uniform in thickness is formed on the substrate.
