Lonestar EDFAS meeting, January 24, 2018 at Microtech Analytical Labs

January 24, 2018 | Microtech Analytical Labs 538 Haggard St. STE 402 Plano, TX 75074. Across the street from the Comfort Suites; see Map link

Quantitative cathodoluminescence (CL) microscopy is a new optical spectroscopy technique that measures electron beam-induced optical emission over a large field of view with unprecedented spatial resolution close to that of a scanning electron microscope (SEM). Correlation of surface morphology (SE contrast) with spectrally resolved and highly material composition sensitive CL emission, opens a new pathway in non-destructive failure and defect analysis on the nanometer scale. Here we present applications of a modern CL microscope in defect and homogeneity metrology, as well as failure analysis in semiconducting electronic materials.
