Deep analysis of ellipsometer principle: polarization state measurement,Ψ /Δ Parameter and film optical constant inversion
Starting from the foundation of polarized optics, this article systematically explains how ellipsometers measure amplitude to angle ratio and PSI; Phase difference angleΔ To achieve high-precision non-destructive characterization of nanoscale film thickness, refractive index n, and extinction coefficient k. Deeply analyze the complex reflectance ratio, dispersion model (Cauchy/Lorentz), and data fitting algorithm, and compare the principles, characteristics, and engineering application scenarios of two mainstream ellipsometry technology routes: multi wavelength laser and phase modulation.
