摘要： To acquire defect images even when a defect exists below an optically transparent film, an electron optical system of an electron microscope is set to a first imaging condition. A defect position of a specimen is set so as to fall within the visual field of the electron microscope, using position data of a defect of the specimen. The position of the defect is imaged by the electron microscope set to the first imaging condition to obtain a first image corresponding to the defect position. The first image is processed to determine whether a defect exists. The electron optical system is then set to a second imaging condition on the basis of the result of determination. A point imaged under the first imaging condition is imaged by the electron microscope set to the second imaging condition to acquire a second image corresponding to a defect position.

摘要： An electron lens comprising a first exciting coil, a second exciting coil, a casing for encompassing the first and second exciting coils, and an excitation control apparatus for controlling the excitation state of at least the first exciting coil independently of the second exciting coil. The excitation control apparatus independently controls currents applied to the first and second exciting coils, respectively. At this time, exothermy of each coil can be kept constant and thermal deformation of the casing can be prevented by keeping the sum of the absolute values of the currents applied to the coils.

摘要： This invention provides a technique for observing defects, which can automatically decide a direction from inclined observation and take an inclined review image. In a defect observing system for detecting the defects and thereafter observing images of the defects from various directions in detail, positions of inclined images to be taken are automatically displayed on a display screen from a planar image (top-down image) of a SEM using CAD data, and the defects are selected from the images displayed on the display screen based on specification by a user, an inclined angle and direction are determined per selected image to take an inclined image (beam-tilt image), and the inclined image of each defect is acquired.
