PROBLEM TO BE SOLVED: To provide a charged particle beam device which, in a relatively simple configuration, corrects off-axis chromatic aberration and deflection coma aberration at the same time.SOLUTION: The present invention is a charged particle beam device provided with a tilting purpose deflector 08 disposed between a charged particle source 01 and an objective lens 09 and used to tilt a charged particle beam, the charged particle beam device having a first optical element 07 including an electromagnetic quadrupole which generates dispersion to suppress the dispersion caused by deflection by the tilting purpose deflector 08 and provided with a second optical element comprising the deflector 06 for deflecting the charged particle beam incident upon the first optical element 07 or an electromagnetic quadrupole which causes dispersion different from the dispersion generated by the first optical element to occur in the charged particle beam.

PROBLEM TO BE SOLVED: To provide a technique advantageous in reducing a measurement error due to a positional shift of a knife edge.SOLUTION: A charged particle beam device including an irradiation unit for irradiating a subject with a plurality of charged particles beams includes: a measuring instrument for measuring characteristics of the plurality of charged particle beams; and a control unit. The measuring instrument includes: a plate which has a plurality of knife edges; and a sensor which detects charged particle beams entering through the plate. The control unit scans one charged particle beams selected from the plurality of charged particle beams relative to the measuring instrument so that the one charged particle beam crosses at least two knife edges among the plurality of knife edges, and generates correction information for correcting a measurement error of the measuring instrument due to deformation of the plate based upon output of the sensor during the scanning.
Abstract:
PROBLEM TO BE SOLVED: To enable an ion beam in an ion beam system having a scanning deflector to be deflected with high accuracy at a high deflection frequency (high speed) and without expanding the dynamic range of a deflection voltage in both high energy and low energy operation modes.SOLUTION: A deflector 39 is composed of three deflection electrode pairs consisting of first deflection electrodes 51a, 51b and 51c disposed at given intervals in the direction of an optical axis 5 of an ion beam 19 and second deflection electrodes 52a, 52b and 52c opposing the foregoing, and is so designed that different electric potentials can be applied to each deflection electrode from a controller 7 via a switch 61. In a first operation mode (for example, 30 keV ion beam energy), a deflection electric field is generated for all of the deflection electrode pairs, as shown by an arrow 55. In a second operation mode (for example, 1 keV ion beam energy), a deflection electric field is generated for only the deflection electrode pair 51a and 52a.
