Patent ID: 11538657

Abstract:
An alignment system that realizes high reproducibility of position information during re-observation and in which a user can efficiently and easily re-observe an area of interest is provided. An alignment system that enables correlative observation between the imaging device 104 and the charged particle beam device 100, in which a plurality of positional alignment points are set on a sample carrier in a state where a sample is placed on the sample carrier, the alignment controller 153 obtains a transformation matrix that transforms a coordinate system of the imaging device and a coordinate system of the charged particle beam device based on position information and magnification of each of the plurality of positional alignment points when a first image is imaged by an imaging device and position information and magnification of each of a plurality of positional alignment points when observing by a charged particle beam device, and transforms a field of view designated for the first image into field-of-view information of the charged particle beam device by using the transformation matrix.
