Abstract
Abstract A unit arrangement part comprises a chemical cabinet on its lowermost part, while coating units for forming a resist film on a substrate and developing units for developing the substrate after exposure are arranged on four corners of an apparatus above the chemical cabinet. Further, multistage thermal processing units for thermal-processing the substrate are arranged on front and rear portions of the apparatus above these wet processing units. A cleaning unit for supplying a cleaning liquid such as pure water and cleaning the substrate is arranged on a front side of the apparatus between the coating units as a substrate processing unit. Thus provided is a substrate processing apparatus having excellent workability in maintenance with a high degree of freedom in arrangement of processing units.
