    摘要： A charge control electrode emitting photoelectrons is disposed just above a wafer (sample) in parallel thereto, and the electrode has a through hole so that ultraviolet light can be irradiated to the wafer through the charge control electrode. Specifically, a metal plate which is formed in mesh or includes one or plural holes is used as the charge control electrode. By disposing the charge control electrode just above the sample in parallel thereto, when negative voltage is applied to the electrode, electric field approximately perpendicular to the wafer is generated. Therefore, photoelectrons are efficiently absorbed in the wafer. Also, by using the charge control electrode having approximately the same size as that of the wafer, charges on a whole surface of the wafer can be removed collectively and uniformly. Therefore, time required for the process can be reduced.

    摘要： Disclosed here is a high resolution scanning electron microscope having an in-lens type objective lens. The microscope is structured so as to detect transmission electrons scattering at wide angles to observe high contrast STEM images according to each sample and purpose. A dark-field detector is disposed closely to the objective lens magnetic pole. The microscope is provided with means for moving the dark-field detector along a light axis so as to control the scattering angle of each detected dark-field signal.

    摘要： Image evaluation method capable of objectively evaluating the image resolution of a microscope image. An image resolution method is characterized in that resolution in partial regions of an image is obtained over an entire area of the image or a portion of the image, averaging is performed over the entire area of the image or the portion of the image, and the averaged value is established as the resolution evaluation value of the entire area of the image or the portion of the image. This method eliminates the subjective impressions of the evaluator from evaluation of microscope image resolution, so image resolution evaluation values of high accuracy and good repeatability can be obtained.
