Masters Theses
Current methods of manufacturing high temperature thin lm superconductors require increasingly more precise and accurate thin lm diagnostics to ensure high quality superconductors. There are several diagnostic tools for monitoring thin lms. However, due to the complex nature of superconducting thin lm stacks, ellipsometric methods are well suited for this application. This study investigates various ellipsometric methods in simulated process control environments.
A computer program was developed to generate ellipsometric data for given film stack characteristics and experimental geometry, and to analyze simulated ellipsometric data to recover optical parameters of the given film stack. The program was used to investigate …
