A charged particle beam device includes: a charged particle source; an optical system which acts on a charged particle beam emitted from the charged particle source; a control unit which controls the optical system; and a storage unit which stores previous setting values of the optical system. The optical system includes a first optical element and a second optical element for controlling a state of the charged particle beam to be incident on the first optical element. The control unit obtains an initial value of a setting value of the second optical element based on previous setting values of the second optical element; and changes a state of the charged particle beam by changing the setting value of the second optical element from the obtained initial value and obtains the setting value of the second optical element based on the change in the state of the charged particle beam.

There is provided a beam alignment method capable of easily aligning an electron beam with a coma-free axis in an electron microscope. The method starts with tilting the electron beam (EB) in a first direction (+X) relative to a reference axis (A) and obtaining a first TEM (transmission electron microscope) image. Then, the beam is tilted in a second direction (&#x2212;X) relative to the reference axis, the second direction (&#x2212;X) being on the opposite side of the reference axis (A) from the first direction (+X), and a second TEM image is obtained. The reference axis is incrementally varied so as to reduce the brightness of the differential image between a power spectrum of the first TEM image and a power spectrum of the second TEM image.
