Abstract

A charged particle beam apparatus includes: a charged particle beam column configured to irradiate an irradiation target with a charged particle beam; a detector configured to detect secondary charged particles emitted from the irradiation target by the irradiation of the charged particle beam; a needle arranged in an irradiation area of the charged particle beam; a needle actuator configured to actuate the needle; and a controller configured to control the needle actuator to actuate the needle along a movement route that is configured by a preset target position and preset way points. The controller controls the needle actuator to set an actuating direction of the needle for each of the way points.
