IC and system design

Our long-term experience in design of analog, mixed-signal, digital IC provides a basis for the realization of customized solutions. The typical applications follow the slogan more-than-moore, in the integration of additional functions.


Technologies for
organic electronics

The strength of Fraunhofer FEP is the availability of numerous processes and equipment as well as clean rooms that enable process development and innovation through combination of methods and processes. Fraunhofer FEP can access various coating technologies, as vacuum evaporation of organic and inorganic material, atomic layer deposition (ALD), print and lamination methods as well as laser ablation.


Electron beam

Generation, shaping and control of the electron beam, its effect on the material and the realization of the necessary process technology, are the key aspects of our work in this core competency.


Design and technology transfer

  • technology transfer and introduction of the process into production
  • technology transfer including fitting plants with key components
    (also retro-fit of existing plants)
  • scale up of processes and technologies for industrial plants
  • transfer of technology and product designs to our customers

In our division Microdisplays and Sensors we offer our clients a broad range of processes in a clean room environment for conducting R&D as well as pilot-scale production of OLED microdisplays and sensors.

Our work focuses on the fabrication of micro- to nanoscale thin films and their structuring. Various facilities and processes are available for this purpose. There are also analytical methods available for characterizing layers.
