Device that holds substrate in substrate holder and/or releases holding of substrate using substrate holder, and plating apparatus including the same

A device that holds a substrate in a substrate holder and/or releases the substrate from the substrate holder,

• wherein the substrate holder comprises
• a first frame facing a first surface of the substrate and used to sandwich the substrate, and
• a second frame facing a second surface of the substrate and used to sandwich the substrate,
• the first frame and the second frame have openings that expose the substrate, respectively,
• the device comprises a substrate supporting unit that sandwiches the substrate between the first frame and the second frame,
• the substrate supporting unit comprises
• a first substrate supporter that supports the first surface of the substrate and
• a second substrate supporter that supports the second surface of the substrate,
• the first substrate supporter is configured to come into contact with the substrate through the opening of the first frame, and
• the second substrate supporter is configured to come into contact with the substrate through the opening of the second frame.
