Title:
CHARGED PARTICLE MICROSCOPE
Document Type and Number:
WIPO Patent Application WO/2011/055521
Kind Code:
A1
Abstract:
Provided is a mechanism whereby an ion irradiation system can be made more compact, the length of the ion optics can be reduced, and the direction in which ions are discharged from an emitter tip (21) toward a sample can be adjusted accurately. The charged particle beam microscope is configured of: a gas field ionization ion source (1); a focusing lens (5) which accelerates and focuses ions that have been discharged from the ion source; a movable first aperture (6) which limits the ion beam that has passed through the focusing lens; a first deflector (35) which scans or aligns the ion beam that has passed through the first aperture; a second deflector (7) which deflects the ion beam that has passed through the first aperture; a second aperture (36) which limits the ion beam that has passed through the first aperture; an objective lens (8) which focuses, on a sample, the ion beam that has passed through the first aperture; and a means for measuring the signal, which is substantially proportional to the current of the ion beam that has passed through the second aperture.
