A substrate processing system includes a film-forming device to form photosensitive film on substrate, an exposure device to expose the film on the substrate, a relay device to transfer the substrate between the film-forming and exposure devices, a warping data acquisition device to acquire measured warping data of the substrate, a communication device to perform data communication with the exposure device, and a control device including film-forming, relay, measuring, and communication control sub-devices. The film-forming sub-device controls the film-forming device to form the film on the substrate, the relay sub-device controls the relay device to transfer the substrate to the exposure device, the measuring sub-device controls the warping data acquisition device to acquire the data after the controlling by the film-forming sub-device prior to the controlling by the relay sub-device, and the communication sub-device controls the communication device to transmit the data to the exposure device.
