[Slice&View] Three-Dimensional SEM Observation Method

By repeatedly performing cross-sectioning processing with FIB and observation with SEM, and reconstructing the obtained images, three-dimensional structural information can be obtained.

Using a high-resolution SEM device equipped with FIB, we can obtain three-dimensional structural information by repeatedly performing cross-sectioning (Slice) with FIB and observing (View) with SEM, and then reconstructing the acquired images. Similarly, Slice & View is also possible for SIM (Scanning Ion Microscope) images. - It is possible to observe secondary electron (SE), backscattered electron (BSE) images, and scanning ion microscope (SIM) images.

basic information

By repeatedly performing cross-sectional processing with FIB and observing with SEM, continuous SEM observation results can be obtained. By integrating SEM data on software, it is possible to obtain a three-dimensional constructed image.
