Abstract
A charged particle beam processing apparatus includes a sample chamber to process a substrate including side faces by a charged particle beam, a movable stage in the sample chamber, the stage including a place on which the substrate is to be mounted, a height and position acquiring unit to acquire a height of the substrate on the stage by irradiating a laser beam onto the substrate on the stage and using the laser beam reflected from the substrate and to acquire positions of at least two adjacent side faces among the side faces based on the acquired height, and a calculating unit to calculate a position of center of gravity of the substrate on the stage and a rotation angle as to a rotary axis vertical to the place on which the substrate is to be mounted based on the positions of the at least two adjacent side faces.
