  • Publication number: 20220098737
    Abstract: The present disclosure relates to a shower head which is fixed to a sidewall through a coupling unit and can prevent a separation from the sidewall, and a substrate processing apparatus including the same. The shower head may be fixed to the sidewall through the coupling unit. Therefore, a second end part of the coupling unit can prevent the coupling unit from falling out of an assist groove, even though the diameter of the assist groove is increased by thermal expansion, which makes it possible to increase a coupling force between the sidewall and the shower head. Furthermore, even when a repair work is performed, the assist groove is not widened. Although only the second end part of the coupling unit is cut, the sidewall can be easily replaced.
