Abstract:
A substrate processing apparatus for applying a coating solution to a substrate and performing heat processing and subsequent cooling processing for the substrate, comprising:a coating processing unit for applying the coating solution to the substrate; a heat processing unit for performing the heat processing for the substrate; a plurality of first cooling processing units for performing the cooling processing for the substrate; a second cooling processing unit, which is temperature-controlled more accurately than the first than the first cooling processing unit, the second cooling processing unit being provided near the coating processing units, for performing the cooling processing for the substrate, said first and second cooling processing units respectively including a plurality of Peltier elements, the number of Peltier elements in each of said first cooling processing units being smaller than the number of Peltier elements in said second cooling processing unit; and a transfer mechanism for transferring the substrate between said units, wherein the substrate which has been subjected to the heat processing by said heat processing unit is subjected to the cooling processing in one of said first cooling processing units or said second cooling precessing unit, and wherein when the substrate is transferred to said coating processing unit, the substrate is cooled in said second cooling processing unit at all times and then directly transferred to said coating processing unit.
