    • A method of manufacturing an aperture stop with a rectangular aperture for an electron beam exposure device, comprising the steps of: preparing a single-crystal silicon substrate with one side having a (100) face; providing a mask on said side of the substrate; selectively etching the substrate through the mask from said side to form a projecting portion of rectangular cross section by anisotropic etching; forming an aperture layer by covering said one side of the etched substrate with a high-melting-point metal having good electric conductivity, thereby surrounding said projecting portion; and forming in said aperture layer a rectangular aperture with a cross section corresponding to the cross section of said projecting portion by removing said substrate from the aperture layer.
    • 一种制造具有用于电子束曝光装置的矩形孔径的孔径光阑的方法,包括以下步骤:制备具有(100)面的一侧的单晶硅衬底; 在所述基板的所述侧面上设置掩模; 通过所述侧面通过所述掩模选择性地蚀刻所述衬底,以通过各向异性蚀刻形成矩形横截面的突出部分; 通过用具有良好导电性的高熔点金属覆盖所述蚀刻的基板的所述一侧来形成开口层,从而包围所述突出部分; 以及通过从所述孔层移除所述基底,在所述孔层中形成具有对应于所述突出部分的横截面的横截面的矩形孔。
