  • Patent number: 10538845
    Abstract: An yttrium oxyfluoride sprayed coating contains Y5O4F7 as a main component. In the yttrium oxyfluoride sprayed coating, when the total intensity of all peaks attributable to yttrium oxyfluoride in a diffraction spectrum obtained by X-ray diffractometry is assumed to be 100, the total intensity of all peaks attributable to yttrium fluoride and yttrium oxide is less than 10. Furthermore, in an yttrium oxyfluoride-containing sprayed coating, when the total intensity of all peaks attributable to yttrium oxyfluoride and yttrium fluoride in a diffraction spectrum obtained by X-ray diffractometry is assumed to be 100, the total intensity of all peaks attributable to yttrium oxide is less than 1.

  • Publication number: 20090169854
    Abstract: To provide a porous member that can suppress energy loss in a microwave band and can evenly disperse gas when used in a field requiring a high level of cleanness. The porous member is formed of porous ceramics and has a dielectric loss tangent of not more than 1×10?3 in a microwave band. A ceramic member has sintered ceramics including the porous member at a part thereof.

  • Publication number: 20090101070
    Abstract: A member for a plasma processing apparatus, which is excellent in film-formability, durability, and reliability, is provided. On a substrate, a ceramic film having a purity not less than 98% is provided. In the ceramic film, grains constituting the film have a grain diameter not greater than 50 nm and the amount of moisture released from the film is not more than 1019 molecules/cm2.
