Abstract
A coating apparatus has a stage module, a temperature regulating module which adjusts a temperature of a substrate to a set temperature, a coating module which applies a coating liquid to the temperature-regulated substrate, and a heating module which heats the coating-liquid applied substrate, arranged in a process section in order from an upstream end of transfer along a transfer path of the substrate, and has a dummy stage placed between the coating module and the heating module so that when by means of a substrate transfer mechanism which has an upper arm and a lower arm, provided one on the other and advanceable and retreatable independently of each other, substrates are transferred one by one from an upstream module to a downstream module in order by alternately operating the upper arm and the lower arm, that arm which performs transfer from the temperature regulating module to the coating module differ from that arm which receives a substrate from the heating module, that numbers are sequentially assigned to downstream modules with the stage module at the upstream end taken as a first module, that substrate which is located on the first stage module is received with the upper arm when the temperature regulating module is an even-numbered module, and the substrate located on the first stage module is received with the lower arm when the temperature regulating module is an odd-numbered module.
