  • Publication number: 20220384154
    Abstract: In a disclosed plasma processing apparatus, an electrostatic chuck provided in a chamber includes a first region on which a substrate is placed and a second region on which an edge ring is placed. The first region includes a first electrode provided therein. The second region including a second electrode provided therein. A first feed line connects the first electrode and a bias power supply generating a pulse of a voltage applied to the first electrode to each other. A second feed line connects the second electrode and the bias power supply or another bias power supply generating a pulse of the voltage applied to the second electrode to each other. The second feed line includes one or more sockets and one or more feed pins. The one or more feed pins have flexibility in a radial direction thereof and are fitted into the one or more sockets.

  • Patent number: 10529599
    Abstract: In a substrate processing apparatus of the present disclosure, a bearing member includes a decaying mechanism provided with a connecting shaft inserted therein and configured to decay radicals or ions; a first member configured to cover the decaying mechanism; and a second member disposed at the connecting shaft and provided with the connecting shaft inserted therein while being in contact with a sealing member. Further, an end of the first member and an end of the second member are connected to be engaged with each other, an invasion path is formed to allow the radicals to invade from the connected portion of the end of the first member and the end of the second member, and the invasion path is formed to be folded back in an extending direction of the connecting shaft. The sealing member is made of a material having a tensile strength larger than 12.1 MPa.

  • Publication number: 20190348262
    Abstract: A plasma processing apparatus is for performing plasma processing in a depressurizable inner space. The apparatus includes a chamber having therein an inner space, a supporting table provided in the inner space and configured to support a substrate to be mounted thereon, one or more first members included in the chamber or separate from the chamber and partially exposed to a depressurized environment including the inner space, and one or more second members included in the chamber or separate from the chamber, each being in contact with a corresponding one of said one or more first members, and partially disposed in an atmospheric pressure environment. The apparatus further includes one or more feeders each of which is configured to supply a coolant to a cavity formed in a corresponding one of said one or more second members.

  • Publication number: 20150122422
    Abstract: A plasma processing apparatus includes a thermally conductive silicone sheet between a mounting table and a focus ring. The thermally conductive silicone sheet has 100 parts by weight to 2000 parts by weight of thermally conductive particles with respect to 100 parts by weight of polyorganosiloxane, and the sheet has a thermal conductivity of 0.2 W/m·K to 5 W/m·K. Further, when the sheet has a shape of 38 mm in length, 38 mm in width, and 3 mm in thickness and is interposed between filter papers each having a diameter of 70 mm and kept under a load of 1 kg at 70° C. for 1 week, a bleed-out amount of a liquid component is 30 mg or less.
