    摘要: An electrostatic chuck device includes an electrostatic chuck section, a metal base section, and a dielectric plate. The electrostatic chuck section has a substrate, a main surface of which serves as a mounting surface for a plate-like sample, an electrostatic-adsorption inner electrode built in the substrate, and a power supply terminal for applying a DC voltage to the electrostatic-adsorption inner electrode. Here, a dielectric plate is fixed to a concave portion formed in the metal base section. The dielectric plate and the electrostatic chuck section are adhesively bonded to each other with an insulating adhesive bonding layer interposed therebetween. The dielectric plate and the concave portion are adhesively bonded to each other with a conductive adhesive bonding layer interposed therebetween, the volume resistivity of which is 1.0×10−2 Ωcm or less.

    摘要: An object of the present invention is to suppress damage of an electrostatic chuck, by controlling stress exerted on each part of a table, which includes an electrically conductive material, i.e., an electrode for generating plasma, a dielectric layer for enhancing the in-plane uniformity of a plasma process, and an electrostatic chuck. The table for a plasma processing apparatus includes an electrically conductive member connected with a high frequency power source and adapted for plasma generation, for drawing ions present in the plasma, or for both thereof; a dielectric layer provided on a top face of the electrically conductive member, having a central portion and a peripheral portion that are different in thickness relative to each other, and adapted for providing uniformity of high frequency electric field intensity in a plane over the substrate to be processed; and an electrode film for an electrostatic chuck, provided in the dielectric layer and adapted for electrostatically chucking the substrate onto a top face of the dielectric layer. With such configuration, the stress exerted on the electrostatic chuck due to temperature change can be controlled.

    摘要: An electrostatic chuck device includes an electrostatic chuck section including a substrate and a power supply terminal for applying a DC voltage to an electrostatic-adsorption inner electrode; and a metal base section fixed to the other main surface of the electrostatic chuck section. Here, a concave portion is formed in the main surface of the metal base section facing the electrostatic chuck section and a dielectric plate is fixed to the concave portion. The dielectric plate and the electrostatic chuck section are adhesively bonded to each other with an insulating adhesive bonding layer interposed therebetween. The dielectric plate and the concave portion are adhesively bonded to each other with an insulating adhesive bonding layer interposed therebetween. The dielectric constant of the insulating adhesive bonding layer is smaller than that of any one of the dielectric plate and the substrate.
