Thin film fabrication technologies
Summary
The students will learn about the essential chemical, thermodynamic and physical mechanisms governing thin film growth, about the most important process techniques and their typical features, including process-microstructure-film properties relationships.
Content
- Introduction (applications, importance, history, overview, vacuum science and technology)
- Major deposition methods with examples and typical applications: evaporation; plasmas, ion beam processing, sputtering; chemical vapor deposition; atomic layer deposition
- Nucleation and growth models, epitaxy
- Film morphology and microstructure
- Interdiffusion, reactions and transformations
- Characterisation techniques of thin films and surfaces
- Mechanical properties of thin films
Examples throughout the chapters mostly from Swiss companies on hard coatings, microelectronics, architectural glass, decorative coatings
