Abstract:
A substrate processing apparatus for processing a large-sized substrate by a photolithography process, comprising:a first module including at least one liquid treatment unit for applying a liquid treatment to a substrate under an atmospheric pressure and at least one heat treatment unit for applying a heat treatment to the substrate under the atmospheric pressure;a second module including at least one surface treatment unit for treating a surface of the substrate under a reduced pressure, said second module being arranged near the first module, and said first module and said second module being arranged integrally,a substrate transfer mechanism for transferring the substrate to the liquid treatment unit, the heat treatment unit, and the surface treatment unit, respectively;a linear transfer path on both sides of which the liquid treatment unit, the heat treatment unit, and the surface treatment unit are substantially linearly arranged, and on which the substrate transfer mechanism is movably mounted for the substrate to be put into and taken out from the liquid treatment unit, the heat treatment unit, and the surface treatment unit, respectively; anda cassette portion provided on at least one side of said linear transfer path for a plurality of cassettes to be put into and taken out from,wherein said substrate transfer mechanism moving on the linear transfer path between the first and the second modules in short time, and transferring the substrate between the first and the second modules quickly.
