    摘要: A charged-particle beam emitting device which includes the following configuration devices so that a lowering in the image resolution will be suppressed even if a primary beam is tilted relative to a sample: A device for causing orbit of the primary beam to pass through off-axes of a plurality of lenses, and controlling off-axis orbit of the primary beam. This device allows the aberration which occurs in the objective lens at the time of beam tilt to be cancelled out by the aberration which occurs in the other lens. Also, there is provided a device for simultaneously modulating excitations of the plurality of lenses including the objective lens.

    摘要: According to the pattern search method of the present invention, detection of a detection image region relative to an observation image is performed by a pattern matching. An image whose size is substantially the same as that of the observation image is used as the detection image region. The detection image region is relatively displaced with reference to the observation image, thereby detecting a degree of similarity for a common region which is common to both of the region and the image. Displacement range of the detection image region is set in advance. If area of the common region is larger than a predetermined value, calculating the degree of similarity will be performed.

    摘要: An object of the present invention is to provide an edge detection technique and equipment which are capable of stably detecting an edge by suppressing the influence of noise even in the case where the image is obtained by charged particle radiation equipment, such as a scanning electron microscope and has a low S/N ratio. More specifically, the present invention is to propose a technique and equipment which are configured to determine a peak position (edge) on the basis of the following two edge extraction techniques. That is, the present invention is to propose a technique and equipment wherein at least two peaks are formed by using, as edge detection techniques, for example, one peak detection technique having a relatively high sensitivity and the other peak detection technique which is relatively less susceptible to the influence of noise than the one peak detection technique, and wherein a position where the peaks coincide with each other is determined as a true peak position (edge position).

    摘要: An auto focus unit, comprising a pursuit block, a lens driver, a detection block, and a controller, is provided. The pursuit block pursues the movements of an optical image of the target-object. The auto focus unit brings an optical image of the target-object into focus on a light-receiving surface. The target-object is desired to be brought into focus. The lens driver causes a focus lens to move so that an optical image of a scanning-area is brought into focus. The detection block detects the light intensity of an area including the scanning area. The controller causes the pursuit block to suspend a pursuit of the target-object when the light intensity detected by the detection block is lower than a predetermined threshold value.
