  • Patent number: 10879033
    Abstract: Provided is a stage apparatus that reduces thermal deformation and temperature rise in an upper table on which a sample is mounted and a charged particle beam apparatus including the stage apparatus. The stage apparatus includes: an upper stage that moves an upper table on which a sample is mounted in a first direction; a middle stage that moves a middle table on which the upper stage is mounted in a second direction orthogonal to the first direction; and a lower stage that moves a lower table on which the middle stage is mounted in a third direction orthogonal to the first direction and the second direction. The upper table and the middle table use a material having a smaller thermal expansion coefficient than in a material of the lower table, and the lower table uses a material having higher thermal conductivity than in the material of the upper table and the middle table.

  • Publication number: 20200352454
    Abstract: An electronic valve with: a yoke including an end plate portion and a side plate portion; a pole piece; a solenoid coil; and a diaphragm made of a plate-shaped magnetic material. The pole piece has an opening at one end portion and a first fluid inlet/outlet communicating with the opening at the other end portion. A biasing unit biases the diaphragm in a direction away from one end portion of the pole piece in a manner of moving the diaphragm translationally in one direction. In a non-operating time, the electronic valve comes into an open state where the opening is open. In an operating time, the diaphragm approaches the one end portion of the pole piece against the biasing force of the biasing unit by a magnetic force generated by the solenoid coil, and the electronic valve can come into a closed state where the opening is closed.
