Abstract

Dynamic Imaging Microellipsometry (DIM) is a fast, high resolution full-field imaging approach to ellipsometry. The testing of the second generation DIM system is described with measurement methodology and system accuracy covered. Relative and absolute errors are discussed separately with analyses of overall accuracy and individual error sources are detailed. Approaches for improving both relative and absolute accuracy are discussed.
