    Abstract: The invention relates to a compound objective lens for a Scanning Electron Microscope having a conventional magnetic lens excited by a first lens coil, an immersion magnetic lens excited by a second lens coil, and an immersion electrostatic lens excited by the voltage difference between the sample and the electrostatic lens electrode. For a predetermined excitation of the lens, the electron beam can be focused on the sample using combinations of excitations of the two lens coils. More BSE information can be obtained when the detector distinguishes between BSE's (202) that strike the detector close to the axis and BSE's (204) that strike the detector further removed from the axis. By tuning the ratio of the excitation of the two lens coils, the distance from the axis that the BSE's impinge on the detector can be changed, and the compound lens can be used as an energy selective detector.

    Abstract: An energy dispersive X-ray analyzer is attached to a scanning electron microscope and includes: a SEM controller; a detector; an EDS controller; and a data processor. The data processor generates first and second X-ray mapping image respectively when the SEM controller controls the scanning electron microscope to irradiate the sample with an electron beam under first and second acceleration voltage conditions. The data processor corrects the first X-ray mapping image and the second X-ray mapping image into images that are independent of acceleration voltage condition based on a measurement intensity variation ratio of the X-ray when changed from the first acceleration voltage condition to the second acceleration voltage condition, and controls the display unit to display a difference image between the corrected first X-ray mapping image and the corrected second X-ray mapping image.

    Abstract: In accordance with an embodiment, a method of adjusting quality of an image of patterns common in shape includes acquiring a first gray value and a first waveform within a reference image, acquiring a sample image, acquiring a second gray value and a second waveform from third and fourth regions within a sample image, respectively, and adjusting the brightness and contrast of the sample image. The first gray value is a standard for the brightness of the image from a first region within a reference image. The first and second waveforms represent a luminance profile of second and fourth regions including edges, respectively. The third and fourth regions correspond to the first and second regions. The brightness and contrast of the sample image are adjusted by matching the first gray value and the first waveform with the second gray value and the second waveform.
