Abstract:
An electron beam proximity exposure apparatus, comprising:an electron beam source which emits an electron beam; an electron beam shaping device which shapes the electron beam; a mask which has an aperture and is disposed on a path of the shaped electron beam; a deflecting and scanning device which deflects the electron beam to scan the mask with the shaped electron beam; a blanker electrode and a blanking aperture which take on-off control of emission of the electron beam; and a stage which holds and moves an object, wherein the mask is disposed in proximity to a surface of the object, and patterns corresponding to the aperture of the mask exposed on the surface of the object with the electron beam having passed through the aperture, wherein the electron beam shaping device comprises an electrostatic cylindrical lens which has power in a single direction which shapes the electron beam into a slender beam of which cross section has a small width in a direction of the scanning and a large width in a direction perpendicular to the direction of the scanning.
