  • Patent number: 9558912
    Abstract: The present invention aims at providing an ion milling apparatus for emitting an ion beam to a sample to process the sample and capable of controlling the temperature of the sample with high accuracy regardless of deformation or the like of the sample being irradiated with the ion beam, and proposes an ion milling apparatus including at least one of a shield holding member for supporting a shield for shielding the sample from the ion beam while exposing a part of the sample to the ion beam; a shifting mechanism for shifting a surface of the sample stand in contact with the sample following deformation of the sample during irradiation with the ion beam, the shifting mechanism having a temperature control mechanism for controlling temperature of at least one of the shield holding member and the sample stand; and a sample holding member disposed between the shield and the sample, the sample holding member deforming following deformation of the sample during irradiation with the ion beam, for example.

  • Patent number: 9343265
    Abstract: The purpose of the present invention is to provide a charged particle beam irradiation apparatus of a relatively simple structure which performs cooling on a sample or a sample stage. An aspect of the present invention comprises: a charged particle source; a sample stage; and a driving mechanism that comprises a transmission mechanism which transmits a driving force to move the sample stage. The charged particle beam irradiation apparatus comprises a container capable of accommodating an ionic liquid (12), wherein the container is disposed in a vacuum chamber. When the ionic liquid (12) is accommodated in the container, at least a portion of the transmission mechanism is provided at a position submerged in the ionic liquid (12).
