1. A substrate processing apparatus comprising:
a support module that supports a substrate and is swingable;
a swing nozzle that is arranged on one side of the support module, moves in a swing manner, and sprays a chemical solution to the substrate;
a sensor arranged on one side of the swing nozzle to sense movement of the swing nozzle;
an electromagnet and a magnet installed on the other side of the swing nozzle so as to be able to adjust spacing relative to each other; and
a controller for receiving a sensing result of the sensor and performing a damping operation to the swing nozzle by providing power to the electromagnet to generate an attractive force or repulsive force between the electromagnet and the magnet.
