发明名称 COATING METHOD AND COATING APPARATUS
摘要 A coating method based on such a technique includes a prewetting step of supplying a prewetting liquid to the center of a substrate (W) and rotating the substrate thereby spreading the prewetting liquid over the whole surface of a first substrate, and a coating film forming step of supplying a coating solution (e.g., a resist solution) to the substrate supplied with the prewetting liquid and drying the coating solution thereby forming a coating film on the surface of the first substrate. The prewetting liquid used is a mixed liquid obtained by mixing a solvent capable of dissolving components of the coating film (e.g., components of resist) and a high surface tension liquid having a surface tension higher than that of the solvent, the mixed liquid having a surface tension higher than that of the coating solution.
