Abstract:
1. A coating film processing apparatus for processing a coating film on a surface of a substrate to be subjected to an immersion light exposure process that performs light exposure through a liquid, the apparatus comprising: a spin chuck configured to hold and rotate the substrate in a horizontal state inside the process container; a rotary mechanism configured to rotate the spin chuck; a solvent-containing liquid supply mechanism configured to supply a solvent-containing liquid comprising a combination of a solvent and a solvent-ability decreasing agent for decreasing solvent-ability onto an edge portion of the coating film on the surface of the substrate held by the spin chuck; a cleaning liquid supply mechanism configured to supply a cleaning liquid onto the edge portion of the coating film on the surface of the substrate held by the spin chuck, and a control section configured to control an operation of the apparatus and including a non-transitory computer readable storage medium storing a control program, wherein the control program, when executed, causes the control section to control the apparatus to conduct a coating film processing sequence that includes supplying the solvent-containing liquid from the solvent-containing liquid supply mechanism onto the edge portion of the coating film, while holding and rotating the substrate by the spin chuck, thereby performing edge portion cutting; and then supplying the cleaning liquid from the cleaning liquid supply mechanism onto the edge portion of the coating film, thereby performing edge portion cleaning, such that the solvent-ability decreasing agent supplied from the solvent-containing liquid supply mechanism and the cleaning liquid supplied from the cleaning liquid supply mechanism consist of the same liquid supplied from the same supply source.
