Abstract:
1. A charged-particle microscope system, comprising: a scanning charged-particle microscope, the scanning charged-particle microscope comprising: a charged-particle optical mirror body; and a control device for controlling the charged-particle optical mirror body; a display screen for displaying a graphical user interface (GUI) comprising an observation image display domain in which an observation image in the charged-particle microscope is displayed; and a computer for executing an operation indicated on the GUI, wherein the GUI displays: a start/stop button for switching on/off an acceleration voltage of the charged-particle optical mirror body; a visual field search button for moving a visual field of the charged-particle microscope observation image displayed on the display screen; an image confirmation button for displaying a higher resolution image than an image displayed where the visual field search button is clicked; an adjustment button to be clicked when the charged-particle optical mirror body is adjusted; a still image button for making an electron beam scan into a still condition in the charged-particle optical minor body; and an observation condition button, the observation condition button comprising: a surface button; a regular button; and a brightness button, wherein, when the visual field search button is clicked, a beam scan is executed that is faster than a beam scan executed when the image confirmation button is clicked, wherein when the adjustment button is clicked, a beam scan is executed that is faster than a beam scan executed when the image confirmation button is clicked, and a size of a beam scanning domain is set narrower than a size of a beam scanning domain set when the image confirmation button is clicked, wherein when the still image button is clicked, the beam scan becomes in the still condition, and the last scanned image is displayed on the observation image display domain, wherein when the surface button is clicked, the acceleration voltage is set lower than an acceleration voltage when the regular button and the brightness button are clicked, and a beam current amount is set smaller than a beam current amount set when the regular button and the brightness button are clicked, and wherein when the brightness button is clicked, the acceleration voltage is set higher than an acceleration voltage set when the regular button and the surface button are clicked, and the beam current amount is set larger than a beam current amount set when the regular button and the surface button are clicked.
