Coated Wafer Mapping Using UV-Vis Spectral Reflection and Transmission Measurements

Confocal Raman microscopy enables detailed and non-destructive analysis of semiconductors. In the video we present the application of confocal Raman microscopy to analyze material characteristics including doping, stress fields, crystallinity and warpage of a 150 mm (6 inch) silicon carbide (SiC) wafer. To maintain this nanoscale-precision across the macroscopically large x and y dimensions of an entire wafer, we used the WITec alpha300 Semiconductor Edition Raman microscope.

Modular Raman imaging microscopes provide a toolset for configuring experiments that can integrate complementary methods and evolve along with individual requirements. Following an introduction to the theoretical background, Dr. Ievgeniia Iermak will describe several of its variations including 3D Raman imaging and optical profilometry-guided measurements. Examples will be provided to demonstrate Raman imaging’s chemical acuity, high resolution, ease of use, and versatility for pharmaceutical research.

A focus on optimizing sample preparation in food and feed analysis can improve laboratory efficiency, data quality, and compliance with regulatory standards. Innovations like advanced microwave digestion and automated reagent handling can streamline workflows, improve safety, and ensure reliable analyses, ultimately supporting overall food safety.

Raman spectroscopy tracks hydrogen blending in gas turbines accurately and reliably, outperforming mass spectrometry with 100% uptime and easy adaptation for new fuels.

Explore the use of Raman to monitor a simple bioprocess, fermentation of glucose with yeast, qualitatively and quantitatively.

Transmission gratings open up many new options for the optical designer. In this tech note, we explore the benefits of transmission gratings over other types.
