Abstract:
A substrate processing system may include at least one transfer device which transfers a substrate between a plurality of substrate processors and includes a first controller which controls the transfer device and a first communication module connected to the first controller, and at least one maintenance device configured to perform maintenance for the substrate processors and includes a second controller which controls the maintenance device and a second communication module connected to the second controller. The first controller may obtain information about the maintenance device through the first and second communication modules to control the transfer device, and the second controller may obtain information about the transfer device through the first and second communication modules to control the maintenance device.
