    Abstract: A cross-section processing-and-observation method, including a cross-section exposure step in which a sample is irradiated with a focused ion beam to expose a cross-section of the sample, and a cross-sectional image acquisition step in which the cross-section is irradiated with an electron beam to acquire a cross-sectional image of the cross-section. The cross-section exposure step and the cross-sectional image acquisition step are repeatedly performed along a predetermined direction of the sample at a setting interval to acquire multiple cross-sectional images of the sample. The method also includes a specific observation target detection step in which a predetermined specific observation target from the cross-sectional image acquired a the cross-sectional image acquisition step is detected. In the specific observation target detection step, after a predetermined specific observation target is detected, the setting interval of the cross-section exposure step is set to be shorter than that before the specific observation target is detected.

    Abstract: A sample preparation method includes processing a sample by an ion beam to form a thin film portion having a thickness that allows an electron beam to transmit therethrough; supplying deposition gas to the thin film portion; and irradiating the thin film portion with an electron beam to simultaneously form a deposition film on a front surface of the thin film portion and a deposition film on a rear surface of the thin film portion opposed to the front surface. The electron beam transmits through the thin film portion, generating secondary electrons from both the front and rear surfaces that decompose the deposition gas to form the deposition films.
