  • Publication number: 20220275514
    Abstract: Provided is a substrate processing apparatus. The positions of a first electrode and a second electrode are adjusted in advance in consideration of differences in coefficients of thermal expansion so that a short circuit created by contact between the first electrode and the second electrode is prevented even in the case in which the first electrode and the second electrode are thermally expanded during processing. Even in the case in which the first electrode and the second electrode are thermally expanded due to an increase in temperature during processing, a short circuit between the first electrode and the second electrode can be prevented, and the uniformity of a thin film can be maintained in the substrate processing apparatus for processing a large substrate.
