  • Patent number: 10818470
    Abstract: A charged particle beam device includes a deflection unit that deflects a charged particle beam released from a charged particle source to irradiate a sample, a reflection plate that reflects secondary electrons generated from the sample, and a control unit that controls the deflection unit based on an image generated by detecting the secondary electrons reflected from the reflection plate. The deflection unit includes an electromagnetic deflection unit that electromagnetically scans with the charged particle beam by a magnetic field and an electrostatic deflection unit that electrostatically scans with the charged particle beam by an electric field. The control unit controls the electromagnetic deflection unit and the electrostatic deflection unit, superimposes an electromagnetic deflection vector generated by the electromagnetic scanning and an electrostatic deflection vector generated by the electrostatic scanning, and controls at least a trajectory of the charged particle beam.
