    摘要: In three-dimensional shape measurement, a backscattered electron detection signal and selection signal generator in a control section controls, by selection signal, a signal switching section and a frame memory so that: detection signals from respective semiconductor elements are sequentially switched in the signal switching section in synchronization with a scanning frame of an electron beam on a sample; and the detection signals from the respective semiconductor elements can be sequentially recorded in recording addresses in the frame memory which correspond to the respective semiconductor elements. After four electron beam scanning sessions, each image data for three-dimensional shape measurement is recorded in the frame memory, and processed in a computing processing section for three-dimensional shape measurement, and the result can be displayed in a display section. The backscattered electron detection signal and selection signal generator in the control section is configured to include, for example, a counter updated in frame scanning units, and can be composed of a very simple circuit or software.

    摘要: An electron microscope according to the present invention includes: a backscattered electron detector provided with a backscattered electron detecting element (9); a low-vacuum secondary electron detector provided with a bias electrode (11) and a specimen stage (12); and a signal switch (14) that switches signals detected by the detectors. Optimal observation conditions are stored in an observation condition memory (20) for each of the detectors. A CPU (19) calls observation conditions stored in the observation condition memory (20) on the basis of the switching of the detectors, and sets conditions of the electron microscope to the called observation conditions. An image processing device (22) converts a plurality of the detected signals obtained on the basis of the switching of the detectors into two-dimensional image signals and evaluates the qualities of images of the two-dimensional image signals. In an image quality prioritized mode, the CPU (19) selects a detector causing an evaluated value to be highest on the basis of the results of the evaluation performed by the image processing device (22) and causes an image to be displayed. In the electron microscope that includes the plurality of detectors, a detector can easily be selected, and the optimal observation conditions for the detectors can easily be set.

    摘要: A signal processing unit (21) of a charged particle microscope calculates a degradation function (H (s)) of an image, on the basis of detection signals (11) obtained by scanning a charged particle beam (2) at two types of scanning speeds, a scanning speed within the bandwidths of a detector (12) and an amplifying circuit at a subsequent stage of the detector, and another scanning speed exceeding the upper limit of the bandwidths. Then, the signal processing unit creates a one-dimensional correction filter for recovering image quality, from an inverse function (H−1 (s)) of the degradation function, and applies the one-dimensional correction filter to the detection signal recorded at the scanning speed exceeding the upper limit of the bandwidths of the detector and the amplifying circuit at a subsequent stage of the detector, or to a two-dimensional image based on the detection signal.
