  • Publication number: 20110000894
    Abstract: The present invention is a cooling block that forms an electrode for generating a plasma for use in a plasma process, and includes a channel for a cooling liquid, the cooling block comprising: a first base material and a second base material respectively made of aluminum, at least one of the first and second base materials having a recess for forming a channel for a cooling liquid; and a diffusion bonding layer, in which zinc is diffused in aluminum, and an anti-corrosion layer of a zinc oxide film, the layers being formed by interposing zinc between the first and second base materials, and by bonding the first and second base materials with zinc interposed therebetween in a heating atmosphere containing oxygen.

  • Publication number: 20100240154
    Abstract: Provided is a temperature control device for controlling a temperature of a member to be exposed to plasma in a substrate processing apparatus. The substrate processing apparatus includes a mounting electrode for mounting a target substrate and a facing electrode positioned to face the mounting electrode, excites a processing gas supplied between the mounting electrode and the facing electrode into plasma, and performs a plasma process on the target substrate with the plasma. The temperature control device includes a heating layer configured to heat a heating target member, a heat insulating layer positioned in contact with an opposite surface to a heating layer's surface facing the heating target member, and a cooling layer positioned in contact with an opposite surface to a heat insulating layer's surface facing the heating layer.

  • Publication number: 20090223449
    Abstract: A cover part is provided in a substrate processing apparatus including a processing chamber for accommodating a substrate, a processing gas diffusing and supplying unit, and a processing gas introducing pipe for introducing the processing gas into the processing gas diffusing and supplying unit. The processing gas diffusing and supplying unit includes an internal space formed therein and widening in parallel to a surface of the substrate accommodated in the processing chamber and gas holes allowing the internal space to communicate with the processing chamber. The processing gas introducing pipe is connected to the internal space via an opening, the opening facing a portion of the gas holes. The cover part covering the opening includes a shielding portion which is disposed within the internal space and has a surface facing the opening and a holding portion which holds the shielding portion at a predetermined position.

  • Publication number: 20050000442
    Abstract: An upper electrode for use in generating a plasma of a processing gas includes a cooling block having a coolant path for circulating a coolant therethrough and one or more through holes for passing the processing gas therethrough, an electrode plate having one or more injection openings for injecting the processing gas toward the substrate to be processed mounted on the mounting table, and an electrode frame installed at an upper portion of the cooling block and providing a processing gas diffusion gap for diffusing the processing gas between the cooling block and the electrode frame. The electrode plate is detachably fixed to a bottom surface of the cooling block via a thermally conductive member having flexibility.
