    Abstract: It is facilitated in a scanning electron microscope to save the labor of executing the reproduction test, conduct basic analysis on a problem caused in execution of the automatic observation process, and confirm details resulting in the error. Upon detecting an error from an abnormality, the scanning electron microscope extracts a sample image lm(t2) obtained by retroceding from a sample image lm(te) stored so as to be associated with time te of error occurrence by a predetermined video quantity (for example, total recording time period t2) previously set and registered by an input-output device, from sample images stored in a recording device while being overwritten, and stores a resultant sample image in another recording device.

    Abstract: The present invention provides a charged particle beam apparatus used to measure micro-dimensions (CD value) of a semiconductor apparatus or the like which captures images for measurement. For the present invention, a sample for calibration, on which a plurality of polyhedral structural objects with known angles on surfaces produced by the crystal anisotropic etching technology are arranged in a viewing field, is used. A beam landing angle at each position within a viewing field is calculated based on geometric deformation on an image of each polyhedral structural object. Beam control parameters for equalizing the beam landing angle at each position within the viewing field are pre-registered. The registered beam control parameters are applied according to the position of the pattern to be measured within the viewing field when performing dimensional measurement. Accordingly, the present invention provides methods for reducing the variation in the CD value caused by the variation in the electron beam landing angle with respect to the sample with an equal beam landing angle and methods for reducing the instrumental error caused by the difference in the electron beam landing angle between apparatuses.

    Abstract: The present invention aims to provide an axis alignment method, astigmatism correction method and SEM for implementing these methods, which can prevent an alignment or correction error attributable to conditions of a specimen. A first aspect is to obtain the difference between the optimal values acquired from an automatic axis alignment result on a standard sample and from each of automatic axis alignment results on a observation target sample, and to correct an optimal value adjusted using the standard sample by use of the difference thus obtained. A second aspect is to acquire an optimal stigmator value (astigmatism correction signal) by using the standard sample, to store the optimal stigmator value as a default value, to add the optimal stigmator value and the default value depending on the height of an observation target sample pattern, and to perform an astigmatism correction on the basis of the resultant stigmator value.

The terminal crimping device further includes a height sensor for outputting a crimp height at the time of crimping said terminals, a data storage unit for storing a pressing time range for determination on whether or not terminal crimping is normal and a crimper height value for determination of said pressing time; and determining unit for time measuring the time during which an output from said height sensor is not larger than the crimper height and determining that crimping is normal if the measured time is within said pressing time range. Thus, the determination on whether or not the terminal crimping is normal can be surely made.

    Abstract: An electron beam is focused on a specimen by a focusing lens. A light beam is incident on the position of irradiation of the specimen with the electron beam and the reflected light beam is detected by a linear light detector. The output of the detector is used to measure the height of the specimen at the position of irradiation of the electron beam. The specimen is moved in a plane perpendicular to an optical axis of the focusing lens. A specimen height measuring device carries out the height measurement of the specimen at a position to be observed on the specimen and at positions thereon which are in the vicinity of the position to be observed, when those positions are located at the position of irradiation of the electron beam. The specimen height measuring device averages the measured values so as to produce a focusing correction signal on the basis thereof and controls the focusing lens on the basis of the focusing correction signal.
