  • Publication number: 20150228462
    Abstract: In a plasma processing apparatus, a partition wall connects a mounting table and a bottom wall of a processing chamber. A power feed member is disposed within the space surrounded by the partition wall and connected to the mounting table. A driving frame extends into the space surrounded by the partition wall from the outside of the sidewall of the processing chamber to be connected to the bottom of the mounting table. A driving mechanism is disposed to the outside of the processing chamber to move the driving frame vertically. At the bottom of a gas exhaust space, an annular gas exhaust passageway is defined by the partition wall and the sidewall and bottom wall of the processing chamber. The gas exhaust unit is interconnected to the gas exhaust passageway through a gas exhaust port at the bottom wall of the processing chamber.

  • Publication number: 20150179415
    Abstract: A substrate processing apparatus includes a chamber including a process chamber for performing a process on a substrate by a gas introduced thereto and an exhaust chamber for evacuating the gas in the process chamber, a shield member for separating the process chamber from the exhaust chamber provided in at least a part of a neighborhood of a side wall of the chamber, and a hollow relay member penetrating through the shield member for communicating the chamber with a pipe connected to a pressure gauge outside the chamber. The relay member is configured to receive a first gas flowing from the chamber into the relay member. The first gas has a first conductance. The first conductance is greater than a second conductance of a second gas flowing from the exhaust chamber into a gap between the relay member and the side wall of the chamber.

  • Patent number: 8687343
    Abstract: A substrate mounting table of a substrate processing apparatus includes a base portion and a circular plate-shaped electrostatic chuck adhered to an upper surface of the base portion by an adhesive layer. The electrostatic chuck has a circular attracting surface to support a substrate. The substrate mounting table further includes an annular focus ring arranged around the electrostatic chuck to surround the substrate and to cover an outer peripheral portion of the upper surface of the base portion. The electrostatic chuck has a two-layer structure including an upper circular part and a lower circular part having a diameter larger than that of the upper circular part. An outer peripheral portion of the lower circular part and an outer peripheral portion of the adhesive layer adhering the lower circular part to the base portion are covered with the focus ring.

  • Patent number: 7655579
    Abstract: A focus ring heat transfer method improves heat transfer of a focus ring arranged in an outer peripheral portion of a mounting surface of a mounting table adapted to mount a target substrate in a chamber. The method includes steps of: disposing a heat transfer sheet between the focus ring and the mounting table; and vacuum-evacuating the chamber prior to processing the target substrate and then restoring the pressure the inside of the chamber to an atmospheric pressure or a light vacuum pressure. Therefore, air present in a fine gap between the heat transfer sheet and the mounting surface is removed to allow the heat transfer sheet to adhere to the mounting surface.
