Electrode 133, and the two beam reflected lights after peroxide film are split and interfere film thickness gauge to receive, due to the presence of thickness, two beams are anti-
Penetrate between light and two beam incident lights there are phase difference, therefore, using fourier transform algorithm or indicatrix fitting algorithm, i.e.,
Finally the thickness of oxide-film is obtained.
It is pointed out that spectral interference film thickness gauge is the principle using white light interferometric method, i.e., with a broadband
Light source measure the reflectance data of different wave length, since reflectivity n and k change with the difference of film, according to this characteristic
To carry out curve fitting so as to try to achieve thickness.The relevant parameter of different kind of material is described by different models, so as to protect
