Each module contains 3 ECTS. You choose a total of 10 modules/30 ECTS in the following module categories:
- 12-15 ECTS in technical scientific modules (TSM)
TSM modules teach profile-specific specialist skills and supplement the decentralised specialisation modules.
- 9-12 ECTS in fundamental theoretical principles modules (FTP)
FTP modules deal with theoretical fundamentals such as higher mathematics, physics, information theory, chemistry, etc. They will teach more detailed, abstract scientific knowledge and help you to bridge the gap between abstraction and application that is so important for innovation.
- 6-9 ECTS in context modules (CM)
CM modules will impart additional skills in areas such as technology management, business administration, communication, project management, patent law, contract law, etc.
In the module description (download pdf) you find the entire language information per module divided into the following categories:
The Technology of thin films is a core element in the design and fabrication of photonic components. The objective of the module "Advanced Thin Film Technology" is the introduction to this important technology and to the applications of thin films in the field of photonics with the focus on optical coatings. This includes the design and fabrication of thin films as well as the characterization of their physical properties.
- Optics: Basics of wave and geometrical optics;
- Physics basics for engineers
- Analysis and linear algebra on FH bachelor level recommended
The students are required to fill possible gaps by self-study. Students without basic knowledge in optics are requested to complete the EVA module "Fundamentals of Light" prior to the "Advanced Thin Film Technology" TSM module.
- are familiar with the main deposition and structuring methods used in thin film technology. They know the advantages and drawbacks of the different methods and are able to select a suitable method for a given thin film design
- know important microstructural, chemical, mechanical, optical, electrical and thermal properties of thin films and are familiar with the relevant methods used in industry to characterize these properties
- understand the main physical concepts related to the application of thin films in photonics and are able to solve simple problems involving thin layers. They are able to perform calculations and evaluations of optical coating designs.
- know the most important applications of thin layers in passive and active devices

- Properties and characterization methods of thin films (~3 weeks)
- Properties such as morphology, microstructure, optical and electric properties, chemical and mechanical properties
- Methods such as atomic force microscopy and profilometry, optical an electron microscopy, focused ion beam, x-ray analytical methods, ion beam based methods (SIMS, RBS) as well ellipsometric and spectroscopic methods
- Physics of thin films (~3 weeks)
- Optical properties:
