Witrynavertical scanning interferometry that can produce a batwings artifact in a step height measurement is described. The skewing occurs at a position on or close to the edge of a step in the sample under measurement when the step height is less than the coherence length of the light source used. A diffraction model is used to explain the effect. WitrynaImproved vertical-scanning interferometry Akiko Harasaki, Joanna Schmit, and James C. Wyant We describe a method that combines phase-shifting and coherence-peak …
