Abstract:
There is provided a charged particle beam apparatus including: a charged particle source; a condenser lens and an object lens for converging a charged particle beam from the charged particle source and irradiating the converged charged particle beam to a specimen; and plural image shift deflectors for deflecting the charged particle beam. In the charged particle beam apparatus, the deflection of the charged particle beam is controlled using first control parameters that set the optical axis of a charged particle beam to a first optical axis that passes through the center of the object lens and enters a predefined position of the specimen, and second control parameters that transform the first control parameters so that the first control parameters set the optical axis of the charged particle beam to a second optical axis having a predefined incident angle different from the incident angle of the first optical axis.

Claim (Index 8):
A charged particle beam apparatus comprising:\n a charged particle source for generating a charged particle beam; a specimen mounting table for mounting a specimen; a condenser lens and an object lens for converging the charged particle beam and irradiating the converged charged particle beam to the specimen; a plurality of image shift deflectors for deflecting the charged particle beam; a storage unit that stores first control parameters that set the optical axis of a charged particle beam to a first optical axis that enters a predefined position of the specimen, and second control parameters that transform the first control parameters so that the first control parameters set the optical axis of the charged particle beam from the first optical axis to a second optical axis that enters the specimen with a predefined incident angle different from the incident angle of the first optical axis, and a control unit, wherein the control unit updates the first control parameters by executing axis adjustment on the first optical axis set by the first control parameters, and controls the deflection of the charged particle beam executed by the plurality of image shift deflectors using control parameters obtained by transforming the updated first control parameters using the second control parameters.
