  • Patent number: 8284538
    Abstract: 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 ?cm or less.

  • Patent number: 7619870
    Abstract: 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.
