1brief introduction
measuring principle-Spectral reflection
spectrumellipsometer(SE) and Spectral Reflectometer (SR) both use the analysis of reflected light to determine the thickness and properties of dielectrics, semiconductors, and metal thin filmsrefractive indexThe main difference between the two is that ellipsometers measure small angles fromfilmReflected light, while a spectral reflectometer measures light reflected vertically from a thin film. Spectral reflectometry measures vertical light and ignores polarization effects (the vast majority of thin films are rotationally symmetric). Because it does not involve any mobile devices, the spectral reflectometer has become a simple and low-cost instrument. Spectral reflectometry can be easily integrated with more powerful transmittance analysis. Spectral reflectometry is usually the preferred method for thin film thicknesses exceeding 10um, while ellipsometry focuses on film thicknesses thinner than 10nm. Both techniques are available for thicknesses between 10nm and 10um. Moreover, spectral reflectometers that are fast, simple, and cost-effective are usually a better choice.
