Vacuum technologies for creating thin-film systems
 Kuchařík, Jan ; Šafl, Pavel (referee) ; Zatloukal, Miroslav (advisor)
The theoretical part of this theses deals with the formation of thin films by vacuum methods. It is a chemical and physical deposition from the gas phase in vacuum environment. Chemical deposition takes place at elevated temperatures, which accelerate reactions. Physical deposition is most often only condensation of vapors of evaporated material. Physical methods are vacuum evaporation, as well as cathodic, ionic, reactive and magnetron sputtering. The formation of thin layers takes place according to 3 known mechanisms. Substrates must be surface treated before the deposition process. The quality of thin films is examined from several perspectives. The practical part is devoted to the production of a thin-film system of copper and tin on a glass substrate. These layers are separated by three different barrier metals. Subsequently, the prepared samples were exposed to thermal stress and were monitored by electron microscope. Diffusion processes at the thin film interface were compared.
