  • Patent number: 9837296
    Abstract: An electrostatic chuck apparatus is disclosed which can be prevented from being damaged or fractured when the temperature abruptly increases or decreases when plasma is irradiated on a plate-like specimen, the heater is heated, or the like, and can also prevent corrosion when a corrosive gas or plasma is provided. The electrostatic chuck apparatus has an electrostatic chuck portion 2 having a mounting plate 11 made of a corrosion-resistant ceramic, a supporting plate 12 which is integrated with the mounting plate 11 so as to support the mounting plate 11 and is made of an insulating ceramic having a larger thermal conductivity than the thermal conductivity of the corrosion-resistant ceramic, and an internal electrode for electrostatic adsorption 13 provided between the mounting plate 11 and the supporting plate 12; and a temperature-controlling base portion 3 which adjusts the electrostatic chuck portion 2 to a desired temperature.

  • Patent number: 9412635
    Abstract: An electrostatic chuck device includes an electrostatic chuck part that has an upper surface as a placement surface for placing a plate-shaped sample and has an internal electrode for electrostatic attraction built therein; and a cooling base part that cools the electrostatic chuck part. The electrostatic chuck part and the cooling base part are integrally adhered to each other via an adhesive layer. An insulator having a double pipe structure including an insulator and an insulator provided coaxially with an outer peripheral portion of the insulator is provided in a cooling gas hole, formed in the electrostatic chuck part and the cooling base part, so as to cover an exposed surface of the adhesive layer on the cooling gas hole side.

  • Patent number: 9343346
    Abstract: An electrostatic chuck apparatus including: an electrostatic chuck section having one main surface that is a mounting surface on which a plate specimen is mounted, and being equipped with an electrostatic adsorbing internal electrode; and a temperature adjusting base section that adjusts the electrostatic chuck section to a desired temperature, wherein a heating member is bonded to a main surface of the electrostatic chuck section, which is opposite to the mounting surface, via an adhesive material, the whole or a part of the main surface of the temperature adjusting base section, which is on the side of the electrostatic chuck section, is covered with a sheet or film of insulating material, and the electrostatic chuck section bonded with the heating member and the temperature adjusting base section covered with the insulating material are bonded and integrated via an insulating organic adhesive layer formed by curing a liquid adhesive.
