Flat Scan Conventional AFM with a piezoelectric tube scanner requires data flattening or leveling because of its intrinsic curved motion. However, this flattening may distort a sample' s micro-surface structure, including its Z value. The newly developed AFM5500M is equipped with a flexure-based scanner that enables well-controlled raster scans along X and Y directions only. As a result, this advanced scanner design can effectively eliminate background curvatures in a wide scan area and improve the accuracy of AFM measurements.
High Orthogonality Using a conventional piezoelectric tube scanner can cause cross-talk when bending the tube scanner. This cross-talk leads to distortions and asymmetrization. The improved AFM5500M’s scanner reduces cross-talk making both accurate and symmetric measurements possible.

Correlation
Correlative AFM and SEM Imaging The Hitachi-proprietary SEM/AFM shared alignment holder provides quick and easy measurements and analysis of topography, structures, composition, and surface property.
AFM and SEM Measurements of the Same Area (Sample:Graphene/SiO2) Overlay images of SEM, AFM (topography), and KFM (surface potential) * It can be concluded from AFM cross-session height measurements that those contrast differences in the SEM image are corresponding to the variation of graphene layers in the AFM image. * It indicates that surface potential (work function) of graphene sheets is highly dependent on the sample thickness, i.e., the number of graphene layers. * High-precision 3D topographic data in conjunction with the electrical property examination provide strong evidence for identifying the root cause of captured variations in SEM contrasts.
Hitachi High-Tech Science will continue to develop AFM-correlated systems with other types of microscopes and inspection equipment.
