Multi-methods surface analysis involving spectroscopic ellipsometry: New measurements for optical and energy applications

  • Surface analysis is still gaining importance, as most modern technology is in essence surface and thin film technology. In microelectronics and optics but also in many fields of energy storage and conversion, thin surface layers or structured surfaces are key components. Optical surface measurements are useful because of their reliability, robustness, and scalability – properties, which are especially desirable in a production environment. However, many of these methods take require considerable effort in data analysis. Spectroscopic ellipsometry (SE) is maybe the prime example of this class of methods. To combine the advantages of SE with metrological trueness and traceability, we combine it in a group of other methods, such as electron microscopy, instrumental surface analysis, X-ray diffraction. This presentation will give an overview on the principles of SE, its available quantities and the general properties of this measurement technique.

This presentation will give an overview on the principles of SE, its available quantities and the general properties of this measurement technique. Several examples from current and past projects of BAM-6.7 will show how a measurement community involving ellipsometry can benefit many fields of interest, from polymer science to energy applications. In the context of creating a “measurement landscape”, standardisation and standard compliance play an important role. The efforts of BAM in standardisation and accrediting of ellipsometry will be shown demonstrating the possible impact on quality assurance in different fields of technology.zeige mehrzeige weniger
