  • Publication number: 20150014529
    Abstract: Provided is a charged particle beam device with high sensitivity, capable of detecting charged particles emitted from a sample at high resolution. An absorption current detector arranged to contact with the sample makes an absorption current generated in the sample by an irradiated charged particle beam flow through the detector, thereby to detect the current. The charged particle beam scans the sample and the charged particle beam device acquires an absorption current image. In case the absorption current detector is arranged separated from the sample, the absorption current detector detects the incident charged particle beam as a signal current dependent on an angle ? formed in a direction from the irradiation position on the sample toward the absorption current detector relative to at least one of the normal line direction of the front surface of the sample and the incident direction of the charged particle beam.

  • Patent number: 8912487
    Abstract: Observation using an FIB image is enabled without causing any damage to a designated region. To this end, an ion beam scanning-prohibited region is set in a sample by using an image acquired by a charged particle beam other than an ion beam, or an image prepared as external data as a peripheral image including the designated region of a sample. Thereafter, the image used to set the ion beam scanning-prohibited region is exactly superimposed on an FIB image acquired for regions except the ion beam scanning-prohibited region, thereby forming an image including the ion beam scanning-prohibited region on which ion beam scanning has not been performed.

  • Patent number: 8680465
    Abstract: A charged particle beam apparatus of the present invention comprises a transmission electron detector (113; 206) having a detection portion divided into multiple regions (201 to 205; 301 to 305), wherein a film thickness of a sample is calculated by detecting a transmission electron beam (112) generated from the sample when the sample is irradiated with an electron beam (109), as a signal of each of the regions in accordance with scattering angles of the transmission electron beam, and thereafter calculating the intensities of the individual signals. According to the above, there is provided a charged particle beam apparatus capable of performing accurate film thickness monitoring while suppressing an error due to an external condition and also capable of processing a thin film sample into a sample having an accurate film thickness, which makes it possible to improve the accuracy in structure observations, element analyses and the like.

  • Patent number: 8530865
    Abstract: A gas field ion source that can simultaneously increase a conductance during rough vacuuming and reduce an extraction electrode aperture diameter from the viewpoint of the increase of ion current. The gas field ion source has a mechanism to change a conductance in vacuuming a gas molecule ionization chamber. That is, the conductance in vacuuming a gas molecule ionization chamber is changed in accordance with whether or not an ion beam is extracted from the gas molecule ionization chamber. By forming lids as parts of the members constituting the mechanism to change the conductance with a bimetal alloy, the conductance can be changed in accordance with the temperature of the gas molecule ionization chamber, for example the conductance is changed to a relatively small conductance at a relatively low temperature and to a relatively large conductance at a relatively high temperature.
