Abstract:
1. A coating and developing system comprising: a carrier handling block for receiving a substrate carried thereto by a carrier; a processing block for processing the substrate transferred thereto from the carrier handling block to form films including a resist film on the substrate; an interface block for carrying the substrate to an exposure system, receiving the substrate processed by the exposure system and returning the substrate to the processing block to subject the substrate to a developing process and to transfer the substrate processed by the developing process to the carrier handling block; wherein a) the processing block is provided with a plurality of film forming unit blocks stacked up in layers, and a developing unit block stacked up in layers with respect to the film forming unit blocks, b) the plurality of film forming unit blocks stacked up in layers include a liquid resist applying unit block for applying a liquid resist to the substrate, a liquid-processing unit block for applying a chemical solution for forming an antireflection film to the substrate before the liquid resist is applied to the substrate, and a liquid-processing unit block for applying a chemical solution for forming an antireflection film to the substrate after the liquid resist has been applied to the substrate; c) each of the unit blocks includes a liquid-processing unit for applying a chemical solution to the substrate, a heating unit for heating the substrate, a cooling unit for cooling the substrate, and a carrying means for carrying the substrate from one to another of the liquid-processing unit, the heating unit and the cooling unit; and d) the unit blocks are provided respectively with transfer stage groups, each of transfer stages stacked up in layers to transfer the substrate from one to another of the carrying means of the unit blocks, disposed on the side of the carrier handling block, and substrate transfer means for transferring the substrate from one to another of the transfer stages.
