Abstract :
The study is aimed at solving the problem associated with simultaneous determination of reflective index and dielectric film thickness in the thickness range of less than 40 nm. This problem has arisen from the needs of the modern nanoelectronics. The article discusses the ways to solve this problem on the basis of optically anisotropic crystals with their unique properties. It is hypothesized that decrease in reflective index with decreasing film thickness is a fundamental phenomenon. This hypothesis is based on the analysis of data obtained from full-scale experiments with SiO2 samples.
