概要(目的・用途・実施内容)/ Abstract (Aim, Use Applications and Contents)

In my experiment, Focused Ion Beam (FIB) technique was utilized for precise microfabrication and analysis of material samples. First, the sputtering function of FIB was employed to perform micronscale cutting in the target area. Additionally, the deposition function of FIB was used to deposit a protective layer in specific regions to prevent potential damage during subsequent analysis. The entire experimental process demonstrated the multifunctionality and high precision of FIB technique, successfully preparing ultrathin samples required for Transmission Electron Microscopy (TEM) analysis and providing strong support for in-depth investigation of the microstructure and properties of materials.

実験 / Experimental

​In the experiment, the Focused Ion Beam (FIB) system NM-510 was utilized to precisely mill a thin specimen measuring approximately 15 micrometers in length, 2 micrometers in thickness, and 4 micrometers in depth from the material sample. Subsequently, the NM-513 Picking Up System was employed to transfer and affix this thin specimen onto a Transmission Electron Microscopy (TEM) grid, facilitating subsequent TEM observation and analysis. This process highlights the high precision and multifunctionality of FIB technology in preparing TEM samples, enabling in-depth investigation of the material's microstructure.

結果と考察 / Results and Discussion

​In this experiment, Focused Ion Beam (FIB) technique was employed to prepare Transmission Electron Microscopy (TEM) samples. By optimizing the FIB preparation parameters, high-quality TEM samples were successfully fabricated.
