Abstract:
A method of processing a substrate having a front surface and a back surface, comprising the steps of:(a) applying a coating solution including a solvent on the front surface of the substrate in order to form a coating film on the front surface of the substrate; (b) pre-baking the coating film after the step (a) has been completed, the pre-baking step including the steps of: (i) heating the substrate; (ii) cooling the heated substrate after the step (i) has been completed; and (iii) heating the substrate after the step (ii) has been completed; and (c) exposing and developing the coating film after the step (b) has been completed; (d) post-baking the coating film after the step (c) has been completed; and (e) placing the substrate in an atmosphere of reduced pressure after performing the step (a) and before performing the step (i), or after performing the step (i) and before performing the step (iii), wherein the heating steps (i) and (iii) are carried out by placing the substrate so that the back surface of the substrate faces a heating plate and is located in close proximity to the heating plate and that only a portion or portions of the substrate contacts a supporting member or members.
