Abstract
A method and system for treating a substrate are provided. The system includes a coating unit, a pre/post-exposure treatment unit, and a developing unit. Each of the units includes a load port and an index module. The pre/post-exposure treatment unit includes first and second modules that are arranged in different layers. The first module performs a process for coating a protective layer on the wafer before an exposure process. The second module performs a process for cleaning the wafer and a post-exposure bake process after the exposure process.
