  • Publication number: 20230268216
    Abstract: A substrate support is arranged in a processing container. The substrate support includes an electrostatic chuck provided with a first support surface for supporting a substrate, provided with a first electrode and a second electrode which are arranged in the electrostatic chuck sequentially from the first support surface, and made of a dielectric material, and a base configured to support the electrostatic chuck. The second electrode is arranged at a position having a distance to the first support surface that is equal to or less than a distance to the base. A voltage for attracting the substrate is applied to the first electrode and bias power is supplied to the second electrode.
