A new calibration approach allows a fast and easy-to-handle geometric calibration of Scanning Electron Microscopy (SEM). This article outlines the application of 3D calibration standards with spatially distributed circular reference markers. The underlying marker-based calibration concept determines scale and shear factors of the coordinate axes and facilitates the analysis of image distortions and other remaining image errors. We present the application of 3D calibration standards, both for 2D and for 3D measurements, and show its contribution to achieving a higher measurement accuracy.

RISE Microscopy has been nominated for a 2015 Photonics Prism Award. These well-respected product innovation awards honor the best new photonic products on the market and are each year presented by SPIE and Photonics Media at a gala event during Photonics West in San Francisco. RISE microscopy is a correlative microscopy technique combining the chemical analysis power of Raman imaging with the ultra-structural characterization capabilities of a scanning electron microscope in an integrated system.

The scanning electron microscope is not only used for precisely surveying the surface topology of samples, but also for determining their chemical compositions. This is done by exciting the atoms to fluoresce under irradiation by an electron beam while scanning the sample. This secondary emission provides information about the location and type of element, insofar as the analysis is sufficiently precise. However, the lighter elements of the periodic table such as lithium, beryllium, boron, carbon, and nitrogen emit secondary fluorescence in an energy range that cannot be sufficiently well resolved by energy dispersive spectrometers (EDS).

Delmic and Phenom World announce DelPhi, the world's first integrated tabletop fluorescence and electron microscope. Delmic produces high performance, user friendly, integrated solutions while Phenom World is a leading producer of electron microscopes. The DelPhi is a complete solution that makes it possible to do fast correlative microscopy with high overlay precision. The system is easy to use for both optical and electron microscopists and makes correlation intuitive and fully automated.

Biological SEM samples usually require a metal coating to avoid charging . However, a good knowledge of the properties and behavior of the samples offers ways to utilize internal electrical conductivity of biological samples for Scanning Electron MIcroscopy (SEM) examination without the need for metal coating. This not only simplifies the preparation, viewing and imaging. It also opens up new ways to examine natural, uncoated surfaces, for example compositional contrast imaging or for the study of adhesion effects.

PML researchers have devised an idea for determining the three-dimensional shape of features as small as 10 nanometers wide. The model-based method compares data from scanning electron microscope (SEM) images with stored entries in a library of three dimensional (3D) shapes to find a match and to determine the shape of the sample. The work provides a powerful new way to characterize nanostructures.
