[Analysis Case] Cross-sectional Observation of TEM/SEM Organic EL and Gate Oxide Film

Low-acceleration STEM observation allows for contrast even in low-density membranes.

For membranes with low density, it is difficult to achieve contrast at high acceleration voltages (hundreds of kV) due to the high transmission capability of the electron beam. However, in low acceleration voltage SEM-STEM images, slight differences in density can be reflected, allowing for clear composition contrast. This can be applied to organic EL films, low-k films, gate oxide films, TEOS films, BPSG films, etc., where the differences in density, average mass, and composition are small. 1) STEM observation using SEM equipment with lower acceleration voltage compared to dedicated TEM equipment. Measurement methods: TEM, SEM Product fields: LSI, memory, display, solar cells, lighting Analysis purposes: Shape evaluation, film thickness evaluation For more details, please download the materials or contact us.
