  • feasibility studies
  • conception of R&D projects including work packages, milestones, and costing
  • OLED fabrication technologies for organic semiconductors
  • CMOS design for controlling the OLED image or sensor devices
  • prototyping
  • organizing fabrication through a network of external foundries
  • creation of the system design based on novel integrated circuit packaging technologies
  • development of processes and procedures for fabricating structured, application-specific OLEDs, such as OLED microstructures and OLEDs for medical applications as well as for organic photodiodes (OPDs)
  • pilot fabrication
  • technology and design transfer as well as licensing for OLED microdisplays, OPDs, augmented-reality (AR) for wearables, optical sensors, fingerprint sensors, etc.

Rigid substrate like silicon wafers or glass as well as flexible substrates can always be employed.

Applications

 

Displays und Wearables

Displays in consumer and professional applications are getting more and more sophisticated. Smart phones, wearables or TVs are equipped with numerous functions to interactively reflect and capture the world.

 

Optics, sensor technology, and electronics

Coating technologies for the growth areas of optics, sensor technology, and electronics are gaining importance for an increasing number of established products and as a prerequisite for new products.

 

Medical applications

The growth in the medical technology sector is being accompanied by a great variety of innovations. The development of new products and medical equipment is often based on sophisticated starting materials.

 

Transport

Today’s cars reflect our individual preferences. A variety of functions can be implemented through thin-films technologies in optics, lighting and interior as well as through novel systems for connected mobility.

  • bi-directional OLED microdisplays
    • in data glasses for improved human-machine interaction
    • as a display element in wearables
    • as an aid for visually impaired people
    • for work support in industrial fabrication, logistics, etc.
    • as fingerprint sensors
  • OLED microdisplays that emiting in the visible and NIR region
  • customer-specific display resolutions SVGA, XGA, VGA, …
  • ultralow-power microdisplays
    • for fitness trackers
    • for monitoring vital parameters in medical applications, etc.…
  • OLED microdisplays for project applications

→ All microdisplays are available as evaluation kits in various versions.

Technologies

 

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.

  • combinability of different processes
  • thin-film encapsulation
  • deposition of high-precision layers and layer systems on wafers with positioning accuracy of ±10 µm
  • wafer encapsulation processes with positioning accuracy of ±1µm
  • thin-film deposition, structuring, and analysis at wafer level (200 mm)
  • 300 m² clean room (class 10)
  • pilot line for OLED-on-CMOS
  • pilot line for rigid substrates
  • pilot line for rigid/flexible substrates
  • facilities for etching, sputtering, and spin-coating
  • deposition using thermal evaporation, electron beam, Vitex/Barix™, and thin-film encapsulation
  • automated wafer-bonding system
  • photolithography
  • wafer prober
