Ellipsometry for thickness measurement
WebAug 2, 2016 · Ellipsometry is the measurement of the effect of reflection on the state of polarization of light. The result of an ellipsometric measurement can be the complex refractive index of the reflecting material, or if the reflecting material is a film-covered substrate, the thickness and optical constants of the film can be determined. WebTFCompanion software is included with all MProbe systems. It is also available as a standalone software for thin-film data analysis (various versions for reflectance, ellipsometry, imaging ellipsometry, etc.) Software plays a critical role in thin-film thickness measurement. It has two distinct functions that are transparent to the user ...
