摘要
The parameters of two dispersion models for Si3N4 dots of multilayer 2D grating are established by the fitting procedures. The Gauss-Newton and Leven berg-M arquardt fitting algorithms are compared. Spectral ellipsometric measurements as the resource of experimental data are reported. In the objective function, various weighting coefficients corresponding to ellipsometric angles are tested.
