Patent attributes
An inspection device includes control unit that acquires pre-charging irradiation amounts for inspection areas on an inspection target. The pre-charging irradiation amounts are based on pattern information for each of the inspection areas. An irradiation unit is provided to control a plurality of first beams to supply the pre-charging irradiation amounts to each of the inspection areas using a corresponding one of the plurality of first beams. After supplying the respective pre-charging irradiation amount to at least one of the inspection areas, irradiation unit controls one of a plurality of second beams to irradiate a pre-charged one of the inspection areas. A generation unit generates images of each of the plurality of inspection areas based on the respective irradiation of the inspection areas with the second beams.
