Abstract
An imaging spectroscopic ellipsometry apparatus and method configured to measure thin films with high spatial resolution. The apparatus includes a rotating compensator that enables to simultaneously collect both spectrometric ellipsometric data and ellipsometric imaging with the use of the same measurement beam of light. Collecting both data sets simultaneously increases the information content for analysis and affords a substantial increase in measurement performance.
