Abstract:
1. Electron beam exposure equipment comprising: an electron gun; an electron optics system irradiating an electron beam emitted from said electron gun on a sample via aligners and two electromagnetic lenses for forming one image; an electron detector used for detecting the position of said electron beam, an aligner control circuit that drives the aligners, a lens control circuit that drives the two electromagnetic lenses, a data control circuit that controls said aligner control circuit and said lens control circuit, and a means for measuring a position of the electron beam, said means for measuring a position of the electron beam measures the position of the electron beam, and said data control circuit gives data for optical adjustment of said electron optics system to said aligner control circuit and said lens control circuit, based on the measured result of the position of the electron beam.
