Title:
COATING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/015138
Kind Code:
A1
Abstract:
The present invention provides a coating method characterized by having: a step for supplying a coating agent to the surface of a lens substrate; a spreading step for spreading the coating agent supplied to the surface by rotating the lens substrate; a first removal step which follows the spreading step and which is for removing, by the rotation of the lens substrate, at least a portion of the liquid residue of the coating agent generated on the peripheral edge section and/or the side surface section of the lens substrate; and a second removal step which follows the first removal step and which is for bringing a suction member into contact with at least the side surface of the lens substrate and removing the liquid residue remaining on the peripheral edge section and/or the side surface section of the lens substrate. According to the present invention, it is possible to provided a coating method with which when a coating layer is formed by using the coating agent on the substrate surface by a spin coating, the liquid residue of the coating agent generated on the peripheral edge section and/or the side surface section of the lens substrate is reduced, and thus, a substrate having a coating layer excellent in uniformity in the film thickness can be obtained.
