Abstract:
A coating and developing system for performing coating and developing treatment for a substrate, comprising:a processing zone having a coating unit for forming a coating film on the substrate, a developing unit for performing development of the substrate, a heat treatment unit for performing heat treatment of the substrate, and a first transfer device for transferring the substrate from/to the coating unit, the developing unit and the heat treatment unit; an interface section in which the substrate is transferred at least on a path between said processing zone and an exposure processing unit outside the system for performing exposure processing for the substrate; a casing for housing said processing zone and said interface section; a gas supply device for supplying an inert gas into said interface section; and an exhaust portion through which an atmosphere in said interface section is discharged, wherein the heat treatment unit, and a second transfer device for transferring the substrate on a path between the heat treatment unit and the exposure processing unit are disposed in said interface section.
