    Abstract: PROBLEM TO BE SOLVED: To provide a charged particle beam apparatus for preventing a charged particle beam from deteriorating by preventing aberration of a convergent charged particle lens from getting worse due to a fact that an optical axis of the charged particle beam toward a sample from a first deflection means and a second deflection means, and toward a charged particle source from the lens is not kept parallel to an optical axis of the lens, and to provide an exposure apparatus, and a device manufacturing method using the exposure apparatus.
    SOLUTION: The charged particle beam apparatus includes a shielding plate having an aperture for permitting a charged particle beam 10 deflected by the first deflection means and deflected by the second deflection means to pass, and charged particles lenses 7 and 8 for converging the charged particle beam passing through the shielding plate to be irradiated onto the sample. The optical axis of the charged particle beam toward the sample from the first and second deflection means and toward the charged particle source from the lens is kept parallel to the optical axis of the lens. Thus, deterioration of the charged particle beam is prevented by preventing the aberration of the convergent charged particle lens from getting worse due to a fact that the optical axis is not kept parallel to the optical axis of the convergent charged particle lens.
