  • Publication number: 20190074209
    Abstract: A dechuck control method of dechucking a processed object electrostatically attracted to an electrostatic chuck is provided. The method includes a step of dechucking the processed object by lifting the processed object with a supporting mechanism. The dechucking step is performed while applying a given voltage to an electrode of the electrostatic chuck.

  • Publication number: 20180366360
    Abstract: Disclosed is an electrostatic attraction method including: a first step in which a gas is introduced into a chamber in which the processing target object is to be processed before a processing target object is placed on a stage within the chamber, and plasma is generated by applying a high frequency power; a second step in which a DC voltage having a polarity opposite to a polarity of a DC voltage to be applied when attracting the processing target object, to an electrostatic chuck provided on the stage after the first step; a third step where extinguishing of the plasma by stopping application of the high frequency power is performed after the second step; and a fourth step where application of the DC voltage is stopped after the third step.

  • Patent number: 5282411
    Abstract: This heat-insulating piston has a piston head comprising a piston head base portion consisting of a ceramic material, a heat-insulating member jointed to the piston head base portion and consisting of a whisker fired member of the same ceramic material as that of the piston head base portion, and a laminate jointed to the surface of the heat-insulating member that faces the combustion chamber, as well as to the surface that slides and consisting of the same ceramic material as that of the heat-insulating member. The heat-insulating member is stably jointed to the piston head base portion and laminate by utilizing the same ceramic material for the heat-insulating member, piston head base portion and laminate, whereby the strength of the piston head can be improved. Furthermore, the heat-insulating capability of the piston can be improved, while the thermal capacity of the laminate is made small, whereby the suction efficiency can also be improved.

  • Patent number: 5018489
    Abstract: In a heat-insulating piston comprising a ceramic cylindrical member having the lower end surface thereof in contact with the outer peripheral upper end surface of a piston skirt member, a head base member having the peripheral portion thereof in contact with an inner peripheral step portion of the cylindrical member and fixed to the piston skirt member, a heat-insulating member disposed on the head base member and a ceramic thin film member disposed on the heat-insulating member and having the peripheral portion thereof bonded to the cylindrical member, this invention relates to a heat-insulating piston which inserts metallic heat-resistant members between the inner peripheral step portion of the cylindrical member and the peripheral portion of the head base member in order to prevent the occurrence of a gap between the thin film member and the heat-insulating member.
