    摘要： An invention providing a scanning electron microscope composed of a monochromator capable of high resolution, monochromatizing the energy and reducing chromatic aberrations without significantly lowering the electrical current strength of the primary electron beam. A scanning electron microscope is installed with a pair of sectorial magnetic and electrical fields having opposite deflection directions to focus the electron beam and then limit the energy width by means of slits, and another pair of sectorial magnetic and electrical fields of the same shape is installed at a position forming a symmetrical mirror versus the surface containing the slits. This structure acts to cancel out energy dispersion at the object point and symmetrical mirror positions, and by spatially contracting the point-converged spot beam with a converging lens system, improves the image resolution of the scanning electron microscope.

    摘要： An irradiation electron beam emitted from an electron gun is deflected by an energy filter, and passes through a first projective lens and an objective lens, and then irradiated onto a sample to produce secondary electrons. The secondary electron beam accelerated by a negative voltage applied to the sample passes through the objective lens and the first projective lens, and deflected by the energy filter to be energy dispersed. Only the secondary electrons having a specified energy pass through energy selecting aperture, and further pass through a second projective lens to form a projected image of the secondary electrons on an imager. Such an electron-optical system may be used for dimension evaluation or inspection of semiconductor substrates.
