  • Patent number: 8663424
    Abstract: There is provided a plasma processing apparatus capable of performing a plasma process while surely supplying a gas. The plasma processing apparatus includes an outer gas supply member having gas supply openings for supplying a plasma processing gas and a jacket configured to support the outer gas supply member within a processing chamber and serving as a gas supply member supporting device. The jacket includes three supporting members installed so as to connect the outer gas supply member and a sidewall and arranged at a certain distance in a direction in which the outer gas supply member extends and mounts fixed to the sidewall so as to mount the supporting members therein. The supporting members include a first supporting member fixed to a first mount and a second supporting member movably supported in a second mount.

  • Publication number: 20130302992
    Abstract: An apparatus for plasma treatment contains a process vessel provided with a mounting table for mounting a substrate, a first gas supplying unit configured to supply a first gas into the process vessel, a first plasma generating unit configured to convert at least a part of the first gas to a first plasma, a second gas supplying unit configured to supply a second gas into the process vessel, and a second plasma generating unit configured to convert at least a part of the second gas to a second plasma. A height of ea an inlet of the second gas from the mounting table is lower than a height of an inlet of the first gas from the mounting table.

  • Publication number: 20120267048
    Abstract: A plasma processing apparatus includes a processing chamber, a stage, a dielectric member, a microwave introduction device, an injector, and an electric field shield. The processing chamber has a processing space therein. The stage is provided within the processing chamber. The dielectric member has a through hole and is provided to face the stage. The microwave introduction device is configured to introduce microwave into the processing space via the dielectric member. The injector has at least one through hole and is made of a dielectric material, e.g., a bulk dielectric material. The injector is provided within the dielectric member. The injector and the through hole of the dielectric member form a path for supplying a processing gas into the processing space. The electric field shield encloses the injector.

  • Publication number: 20110186226
    Abstract: A gas supply member includes an annular portion in which a passage for a gas extending to have an annular shape is provided. The annular portion includes a first member having an annular shape and including a flat plate portion in which a plurality of gas supply holes through which a gas is supplied are formed, and a second member having an annular shape and forming a space, which becomes the passage for the gas, between the first member and the second member.
