Abstract:
1. A periphery coating method of coating a coating liquid on a periphery region of a substrate, the method comprising: performing a scan-in process of moving the coating liquid nozzle from an outside of an edge of the substrate to a position above the periphery region of the substrate while rotating the substrate and discharging the coating liquid from the coating liquid nozzle; and performing a scan-out process of moving the coating liquid nozzle from the position above the periphery region of the substrate to the outside of the edge of the substrate while rotating the substrate and discharging the coating liquid from the coating liquid nozzle, wherein, in the scan-out process, the coating liquid nozzle is moved at a speed lower than a speed at which the coating liquid is moved to a side of an edge of the substrate.
