In fields such as semiconductors and materials science, it can be used for high - precision sample preparation, high - resolution imaging analysis, and precision nano - fabrication. For example, it can prepare ultrathin samples for transmission electron microscopy observation, and analyze the microstructure, composition, and defects of materials.Technical Principle: It integrates a 40kV gallium ion focused ion beam (FIB) column with an ultra - high - resolution Schottky field - emission scanning electron microscope (FE - SEM) technology. The FIB emits an ion beam to process the sample, and the SEM observes the sample state in real - time. Designs such as the low - aberration FIB optical system ensure the stability and accuracy of processing and imaging.Performance: The FIB acceleration voltage is 1 - 40 kV, with a maximum beam current of over 50 nA at 40 kV. The scanning ion microscope (SIM) resolution reaches 5 nm at 40 kV, with a magnification of ×60 - ×250,000. It uses a gallium liquid metal ion source and a low - aberration two - stage electrostatic lens system. The SEM acceleration voltage is 0.5 - 30 kV, with a resolution of 1.0 nm at 15 kV and 2.1 nm at 1 kV. The magnification is ×250 - ×800,000 in high - magnification mode and ×70 - ×2,000 in low - magnification mode. The electron source is ZrO/W Schottky emission, and a three - stage electromagnetic lens reduction system is adopted. It is equipped with a conventional off - center sample stage, and an ultra - stable sample stage for TEM can be optionally configured. It has patented micro - sampling technology, which can be used for the newly developed absorbed current imaging to assist in fault isolation.
