Abstract

PURPOSE:To eliminate the deflection of electron beams by a method wherein a sample chamber formed by a ferromagnetic material and a sample stage, whose upper surface portion is formed by a high permeability material, are magnetically connected and a closed magnetic path is made up. CONSTITUTION:A sample chamber 1 on which an electron optical camera 3 containing a projecting lens 2, other lens systems and an electron gun is placed is built up by a ferromagnetic material such as soft steel while a stage 5, to which a nonmagnetic holder 7 is attached through a high viscous material 6 such as Teflon and on which a sample 4 is set, a stage 8, guide rails 9, 14, etc. are formed by a high permeability material such as pure iron. Thus, a closed magnetic path shown in a broken line is made up, the deflection of electron beams is prevented even when a driving mechanism, etc. contain a ferromagnetic material, and exposure by the electron beams having higher speed and high accuracy can be conducted.
