Coating and developing apparatus

Abstract

Provided is a coating and developing apparatus composed of an assembly of plural unit blocks. A first unit-block stack and a second unit-block stack are arranged at different positions with respect to front-and-rear direction. Unit blocks for development, each of which comprises plural processing units including a developing unit that performs developing process after exposure and a transfer device that transfers a substrate among the processing units, are arranged at the lowermost level. Unit blocks for application, or coating, each of which comprises plural processing units including a coating unit that performs application process before exposure and a transfer device that transfers a substrate among the processing units, are arranged above the unit blocks for development. Unit blocks for application are arranged in both the first and second unit-block stacks. Unit blocks for application which a wafer goes through are determined depending on the layering positional relationship between an antireflective film and a resist film. An exposed wafer goes only through the unit block for development without going through any one of the unit blocks for application.
