Abstract:
The objective of the present invention is to propose a charged particle beam device with which an imaging optical system and an irradiation optical system can be adjusted with high precision. In order to achieve this objective, provided is a charged particle beam device comprising: a first charged particle column which serves as an irradiation optical signal; a deflector that deflects charged particles which have passed through the inside of the first charged particle column toward an object; and a second charged particle column which serves as an imaging optical system. The charged particle beam device is provided with: a light source that emits light toward the object; and a control device that obtains, on the basis of detection charged particles generated according to irradiation of light emitted from the light source, a plurality of deflection signals which maintain a certain deflection state, and that selects or calculates, from the plurality of deflection signals or from relationship information produced from the plurality of deflection signals, a deflection signal that satisfies a predetermined condition.

Claim (Index 6):
The charged particle beam device according to  claim 1 , comprising an image pickup device arranged inside the second charged particle column,\n wherein the control device obtains the plurality of deflection signals such that the charged particles reach a predetermined position, the charged particles being generated based on the irradiation of the light and passing through inside the second charged particle column to reach the image pickup device, or such that the charged particles reach a position identical to a pattern position projected on the image pickup device when the deflection by the deflector is not performed.
