Abstract
In an exemplary embodiment, a substrate processing apparatus is provided. The substrate processing apparatus includes a processing chamber, a substrate support stage. The piezoelectric element is disposed around an opening of the second nozzle to reduce a cross-sectional area of the opening of the second nozzle in accordance with a voltage applied thereto. The thermoelectric element is disposed between the first collection pipe and the second collection pipe to generate an electromotive force corresponding to a temperature difference between the heat transfer medium in the first collection pipe and the heat transfer medium in the second collection pipe. The drive circuit is configured to apply a voltage corresponding to a magnitude of the electromotive force, to the piezoelectric element.
