摘要:
An electron beam exposure system is designed to correct a proximity effect. The electron beam exposure system includes: an electron beam generation unit for generating an electron beam; an electron beam exposure mask having opening portions that are arranged so that sizes of the opening portions change at a predetermined rate in order of arrangement; a mask deflection unit for deflecting the electron beam on the electron beam exposure mask; a substrate deflection unit for deflecting and projecting the electron beam onto a substrate; and a control unit for controlling deflection amounts in the mask deflection unit and the substrate deflection unit. The direction or directions of the change may be any one of a row direction and a column direction or may be the row and column directions.
