Abstract:
An object of the present invention is to provide a charged particle beam device capable of correcting an image drift caused by stage deformation or the like during imaging immediately after stage movement. In order to achieve the above object, proposed is a charged particle beam device including: a sample chamber; a sample stage arranged in the sample chamber; a charged particle beam source which releases a charged particle beam; a deflector which deflects the charged particle beam released from the charged particle beam source; a focusing lens which focuses the charged particle beam; and a control device that controls the sample stage and the deflector, in which the control device calculates a deflection signal to be supplied to the deflector based on a thrust information when driving of the sample stage and a coefficient assigned for each position of the sample stage.
