Graduation and Research Theses

Especially for students of electrical engineering and photonic engineering.

Student Theses during the COVID-19 Pandemic

The implementation of research and theses at the IGM will continue to be possible despite the current restrictions caused by the COVID-19 pandemic. In order to reduce the number of people present at the institute at the same time, the IGM offers remote access to servers and programs for students so that some of the work can be carried out from home. Work in the IGM's clean room is also possible during the pandemic. Laboratories and measuring stations outside the clean room can also be used in compliance with the applicable distance and hygiene rules and the applicable Corona regulations.

Fields of Research

Silicon is the classic semi conducting material for thin film transistors (TFTs). The IGM can process TFTs based on amorphous, microcrystalline, or laser-crystallized poly-crystalline silicon. While amorphous silicion is well suited for large area processing (in tv substrates of up to 10m2), poly-crystalline silicon offers far better (up to a factor of 100) carrier mobility and the option of processing complex CMOS circuits directly on glass. 

Projects in this field include

  • Simulation and design of poly-crystalline silicon circuits
  • Processing of thin film elements and circuits
  • Electronic characterization of processed elements
  • Optimization of thin film processing techniques
  • Processing of active matrices in poly-crystalline silicon

Thin film transistors (TFTs) are the basic elements for integrated circuits used in LCD or LED/LCD flat panel displays (computer monitors, tvs, tablets, and smartphones). Current developments aim at replacing the dominant LCD technologies with active matrix OLED (AMOLED) technologies. At the moment, AMOLED displays for mobile devices are implements using comparatively costly poly-crystalline silicon transistors. Metal-oxide semiconductors like Indium-Gallium-Zinc-Oxide (IGZO) can offer a cheaper alternative as the semi-conductor in TFTs. In addition, combining IGZO with OLEDs would allow the production of completely transparent displays.The IGM offers the capabilities to develop and realize large area transparent integrated thin film circuits from the simulation to the pruduction of photo lithographic masks to the final processing.

Metrology at the IGM focuses on the determination of the physical properties of thin films and liquid crystal cells. It serves to evaluate and to improve current processing techniques. The IGM features a variety of instruments and techniques to characterize for example thin film transistors and thin film capacities.

  • Setting up or expanding existing metrology systems
  • Programming of automated measurement processes
  • Adaptation of a measurement robot for additional automated measurement processes

Control and address circuits form the interface between a display (e.g. AM-LCD) and the graphics or video signal. They can be separated into the driver circuits for addressing the actual pixels, attached directly to the screen, and the interface adapting the input signal to address those driver chips.

Projects in this field:

  • Testing of drivers and signal sources
  • Programming (e.g. FPGAs in VHDL)
  • Circuit design
  • Simulation

Shifting the processing of signals from electronics to optical systems can help improve the efficiency pf optical signal transfers. Optical signal processing can be realized in a variety of ways, from well-established interference filters to using active components loaned from display technologies.

Projects in this field:

  • Design and synthesis of optical thin film filters
  • Design of numerical methods for the synthesis and analysis of optical filters
  • Programming of algorithms for the synthesis and analysis of optical filters (Maple, MATLAB, C/C++)
  • Processing of optical thin film filters
