Course objectives
The course provides an introduction to the deposition of thin films and surface modifications. The overview of the methods is structured into several basic types: physical vapor deposition - PVD (vacuum evaporation and magnetron sputter-deposition), chemical methods (chemical vapor deposition - CVD, atomic layer deposition - ALD and epitaxy) and plasmachemical methods (plasma modification of surfaces, plasma enhanced chemical vapor deposition - PECVD). The students will learn about the principles and the processes taking place during different deposition methods and modification of surfaces. The course informs about experimental conditions and requirements of different methods. The theoretical information are applied to specific examples of the processes important for industrial applications. The lectures are supplemented by laboratory tasks providing examples of several processes in the laboratories of Department of Physical Electronics and CEITEC Nano Research Infrastructure.
Learning outcomes
At the end of the course, the student will be able to: explain principles of thin film deposition utilizing gases/vapors;
explain basic processes taking place during material evaporation and sputtering of targets with energetic particle beams;
describe processes taking place in plasma of electrical discharges;
name different types of plasma sources/reactors for the deposition of thin films and surface modifications;
describe various methods of thin film deposition (vacuum evaporation, magnetron sputtering, CVD, ALD, epitaxy, PECVD) with the emphasis on differences in underlaying processes and experimental requirements of these methods;
suggest suitable thin film deposition method considering the final requested parameters of the product.
