    Abstract: Provided is an ion beam device provided with a gas electric field ionization ion source which can prevent an emitter tip from vibrating in a non-contact manner. The gas electric field ionization ion source is comprised of an emitter tip (21) for generating ions; an emitter base mount (64) for supporting the emitter tip; an ionizing chamber which has an extraction electrode (24) opposed to the emitter tip and which is configured so as to surround the emitter tip (21); and a gas supply tube (25) for supplying gas to the vicinity of the emitter tip. The emitter base mount and a vacuum container magnetically interact with each other.

    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.

    Abstract: An ion beam processing apparatus includes an ion beam irradiation optical system that irradiate a rectangular ion beam to a sample held on a first sample stage, an electron beam irradiation optical system that irradiates an electron beam to the sample, and a second sample stage on which a test piece, extracted from the sample by a probe, is mounted. An angle of irradiation of the ion beam can be tilted by rotating the second sample stage about a tilting axis. A controller controls the width of skew of an intensity profile representing an edge of the rectangular ion beam in a direction perpendicular to a first direction in which the tilting axis of the second sample stage is projected on the second sample stage surface so that the width will be smaller than the width of skew of an intensity profile representing another edge of the ion beam in a direction parallel to the first direction.
