Abstract: A plasma processing apparatus includes a first electrode and a second electrode so arranged in the upper portion of a processing chamber as to face a mounting table, a gas supply unit for supplying a processing gas between the first electrode and the second electrode, a RF power supply unit for applying a RF power between the first electrode and the second electrode for converting the process gas supplied between the electrodes into a plasma, and a gas exhaust unit for evacuating the inside of the processing chamber to a vacuum level from the lower portion of the processing chamber. Since the electron temperature in the plasma is low near a substrate on the mounting table, damage to the substrate caused by the plasma can be suppressed. In addition, since a metal can be used as a material for the processing chamber, the processing chamber can have good temperature controllability.

Abstract: Disclosed is a plasma processing apparatus wherein good temperature controllability is obtained in the side wall of the processing vessel and damage to the substrate by plasma is suppressed. Specifically disclosed is a plasma processing apparatus (1) comprising a first electrode (31) and a second electrode (32) so arranged in the upper portion of a processing vessel (11) as to face a stage (2), a gas supplying unit (4) for supplying a process gas between the first electrode (31) and the second electrode (32), a high-frequency power supply unit (33) for applying a high-frequency power between the first electrode (31) and the second electrode (32) for changing the process gas supplied between the electrodes (31, 32) into a plasma, and an evacuation system (14) for vacuum evacuating the atmosphere within the processing vessel (11) from the lower portion of the processing vessel (11). Since the electron temperature in the plasma is low near a substrate B on the stage (2), damage to the substrate B caused by the plasma can be suppressed. In addition, since a metal can be used as a material for the processing vessel (11), the processing vessel (11) can have good temperature controllability. ® KIPO & WIPO 2009
