Watch it nowThe combination of Atomic Force Microscopy (AFM) and Raman spectroscopy provides deep insights into the complex properties of various materials. While Raman spectroscopy facilitates the chemical characterization of compounds, interfaces and complex matrices, offering crucial insights into molecular structures and compositions, including microscale contaminants and trace materials. AFM provides essential data on topography and mechanical properties, such as surface texture, adhesion, roughness, and stiffness at the nanoscale.
Watch it nowThe growing of semiconductor materials industrialization requires technologies to characterize their properties. Optical microspectroscopic platforms like Raman microscopes offer both physical and chemical information in one system. Thus, process qualification, wafer uniformity assessment, or defects inspection of wafers can be achieved with Raman microscopy. These can also be applied to new materials characterization.
In this webinar, we will highlight how Photoluminescence and Raman microscopies can address semiconductor challenges. We will also show how the combination of micro-spectroscopies with AFM (Atomic Force Microscopy) can provide nano resolution and deeper understanding of these structures.
