Abstract:
1. A coating and developing system comprising: a coating unit for coating a surface of a substrate with a resist, a developing unit for processing the substrate by a developing process after exposing the substrate coated with a transparent liquid layer, and a first cleaning means for cleaning the surface of the substrate coated with the resist to remove components of the resist that may dissolve in the liquid layer when the surface of the substrate coated with the resist comes into contact with the liquid layer with a cleaning liquid before exposure, wherein the first cleaning means comprises: a substrate holding device for holding the substrate in a horizontal position, a cleaning nozzle provided with pouring openings arranged along the width of the substrate to pour the cleaning liquid onto the surface of the substrate held by the substrate holding device, and suction openings arranged adjacently to the pouring openings on a front and/or a back side of the pouring openings to suck up the cleaning liquid from the surface of the substrate, and a cleaning nozzle moving means for horizontally moving the cleaning nozzle relative to the substrate holding device.
