    摘要: A plasma processing method according to an exemplary embodiment includes preparing a substrate in a chamber of a plasma processing apparatus. The substrate is disposed on a substrate support in the chamber. The substrate support includes a lower electrode and an electrostatic chuck. The electrostatic chuck is provided on the lower electrode. The plasma processing method further includes applying a positive voltage to a conductive member when plasma is being generated in the chamber for plasma processing on the substrate. The conductive member extends closer to a grounded side wall of the chamber than the substrate.
