ABSTRACT:
Dynamic imaging microellipsometry (DIM) is a rapid full-field imaging technique for high resolution studies of thin-films. The DIM concept is based on radiometric polarizer, compensator, specimen, analyzer (PCSA) ellipsometry combined with video and image processing techniques. The theoretical basis for this approach is developed using the Jones vector and matrix formalism. Basic systems design is presented with error model predictions of ellipsometric accuracies better than 0.1.degree. for full-field .psi. and .DELTA. images captured in a few seconds with spatial resolution under 10 microns.
