  • Publication number: 20080106842
    Abstract: A mounting device includes a mounting body for sustaining a target object to be processed thereon; an electrostatic chuck disposed on the mounting body and having an electrode layer interposed between insulating layers, and the electrostatic chuck serving to electrostatically attract and hold the target object on a surface of the insulating layer by a electrostatic force generated between the electrode layer and the target object by a voltage applied to the electrode layer. Herein, an electrostatic chuck layer, which is one of the insulating layers on the side of a top surface of the electrode layer, is made of a plasma spray coating of yttrium oxide, which is formed by a plasma spraying, having a thickness of about 200 ?m to 280 ?m, and the electrostatic chuck layer has a surface roughness dependent on a particle diameter of the yttrium oxide used in the plasma spraying.

  • Publication number: 20060081337
    Abstract: A capacitive coupling plasma processing apparatus includes a process chamber configured to have a vacuum atmosphere, and a process gas supply section configured to supply a process gas into the chamber. In the chamber, a first electrode serving as a cathode electrode, and a second electrode grounded to serve as an anode electrode are disposed opposite each other. An RF power supply is disposed to supply an RF power to the first electrode to form an RF electric field within a plasma generation region between the first and second electrodes, so as to turn the process gas into plasma. The target substrate is supported by a support member between the first and second electrodes such that a process target surface thereof faces the second electrode. The second electrode includes a conductive counter surface facing the first electrode and exposed to the plasma generation region.
