Abstract
Current trends in the development of thin-film technologies and the semiconductor industry lead to a decrease in the characteristic dimensions of the structures being created, which places increased demands on the control of their geometric characteristics - layer thicknesses. Methods for determining the thickness of thin metal films are considered. Thin films of amorphous selenium, silver and silver layers on a selenium film are synthesized. Optical transmission spectra are recorded using a UV-vis spectrophotometer. A new method for determining the thickness of thin metal films by the interference effect on certain thicknesses of selenium films is proposed. The corresponding calculations are carried out.

Keywords
thin-film systems, selenium films, thin metal films, silver, interference maxima, spectrophotometry, film electrodes for capacitors, measurement of metal film thicknesses
