Abstract

A multiple electron beam irradiation apparatus includes an electromagnetic lens configured to refract multiple electron beams incident, an aberration corrector arranged in the magnetic field of the electromagnetic lens and configured to be able to individually apply a bias potential and a deflection potential to each of the multiple electron beams, and an objective lens configured to focus the multiple electron beams, a trajectory of the each of which has been individually corrected by the bias potential and the deflection potential, onto a target object.
