Abstract
A charged-particle beam system is offered which is equipped with a Z-motion mechanism to enable tomography. The Z-motion mechanism includes a rotary disk having three tapering surfaces on which balls are nested. The rotary disk is rotated via a worm gear to cause the balls to go upward along the tapering surfaces. This pushes an overlying elevatable disk upward, i.e., in the Z-direction. Consequently, the specimen stage is pushed up in the Z-direction.
