Abstract
A charged-particle beam system has a demagnifying lens for reducing the dimensions of an electron beam produced from an electron beam source, an objective lens for focusing the demagnified beam onto the surface of a target, a first deflector located before the demagnifying lens, a second deflector placed such that the deflection field produced by it is totally or partially superimposed on the objective lens field, and a third deflector located in a stage following the second deflector. An image of the light source is created by the demagnifying lens. An image of the light source image is formed on the target by the objective lens.
