The conditions effect of obtaining CdS and CdSe thin films by a chemical surface deposition method (CSD) on their structural and optical properties has been studied. The optical transmission, absorption spectra and surface morphology of films and degree of phase uniformity were investigated. The content of cadmium ions in the obtained coatings by the method of voltammetry inversion was defined. The thickness of the obtained semiconductor films was calculated according to the mass of cadmium. The optimum conditions for obtaining CSD films of the given thickness with a minimum number of defects on the surface were established.
