PhD thesis in IC Design, Focusing on new CMOS backplane architectures for OLED microdisplays

The Fraunhofer-Gesellschaft ( currently operates 76 institutes and research institutions throughout Germany and is the world’s leading applied research organization. Around 30 000 employees work with an annual research budget of 2.9 billion euros. 

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP is working on innovative solutions in the field of vacuum coating and surface treatment as well as the combination of organic electronics with classical silicon circuitry. The Fraunhofer FEP thus offers a wide range of research, development and pilot-manufacturing.


Our interdisciplinary field of "Microdisplays and Sensors" is engaged in the development and manufacturing of micro-displays and sensors based on the integration of organic light emitting diodes (OLED) onto silicon CMOS substrates. Here, our activities range from the initial idea, through design in close cooperation with the OLED technology, the circuit design of the OLED integration, testing, assembly and interconnection technology to the development of the complete system and application. Here, we are working in the interdisciplinary scope of different subjects such as electrical engineering/electronics, microelectronics, microsystems technology, information technology, computer science, physics, chemistry, optics and manufacturing.

We offer you a topic for a PHD thesis at our location Maria-Reiche-Str. in Dresden-Klotzsche as soon as possible.


What you will do

As part of your dissertation, you will develop new architectures for ultra-low power and low-latency architectures of CMOS backplanes for OLED microdisplays. Such microdisplays are used in wearables, e.g. for augmented- and/or assisted-reality (AR) applications.

Wearables require low power consumption, both for the backplane (pixel cell array) and the respective emitters. AR in the tactile Internet also requires extremely low latencies (<1ms), which require new pixel cell, interface and data transmission architectures.
This interdisciplinary task requires a sound knowledge of CMOS circuit technology as well as the technological integration of emissive semiconductor layers on silicon wafers.

An interesting, challenging and varied task awaits you in a highly innovative environment of research and development. You will be responsible for the following tasks:  
• Development, implementation and experimental validation of concepts for CMOS integrated optoelectronic sensors,
• Design of analog, digital and mixed (mixed signal) integrated circuits,
• Layout design for CMOS and OLED manufacturing,
• Close cooperation with multidisciplinary departments and research partners (for example, OLED technology and manufacturing),
• Development and implementation of Device and Test Specifications,
• Technical and statistical evaluation of measurement results, circuit and device documentation.
The Fraunhofer FEP works for both industrial and public clients. According to this, contacts with international customers from industry, academic partners and funders are to make and maintain, specifically also within the CeTI cluster.

A participation in project acquisition and management is explicitly encouraged.


What you bring to the table

You have a university degree (Master, Diploma) in electrical engineering (microelectronics, information technology), physics or similar programs.

  • Good knowledge of digital and very good knowledge of analog semiconductor circuit technology, practical experience in the complete analog design flow as well as practical experience with design tools from cadence are necessary!
  • Experience in full digital and mixed-signal design flow are very beneficial,
  • In addition, good English skills are required, and German is highly appreciated.

You should be resilient and flexible, enjoy working with people and your work style should be characterized by commitment, the introduction of own ideas and accuracy in handling the necessary tasks. We expect strong organizational skills and a professional presence in dealing with international scientists, customers and public institutions/funders and the willingness to assume responsibility as well as team spirit and joy of work.


What you can expect

  • A responsible and challenging field of activity with plenty of scope for implementing your own ideas,

  • A collegial working atmosphere in a committed team with exciting research projects and state-of-the-art machine and testing technology,

  • Close supervision and support from scientific staff,

  • A modern and internationally oriented working environment,

  • Demand-oriented development opportunities through further training measures and individually tailored personnel development,

  • Collectively agreed holiday entitlement of 30 days as well as a work-life balance through flexible working hours, the possibility of mobile working and support services to reconcile family and career,

  • Company pension scheme (VBL).


Appointment, remuneration and social security benefits based on the public-sector collective wage agreement (TVöD). Additionally Fraunhofer may grant performance-based variable remuneration components.


This vacancy is initially limited for 3 years and also available on a part-time basis. 


We value and promote the diversity of our employees' skills and therefore welcome all applications - regardless of age, gender, nationality, ethnic and social origin, religion, ideology, disability, sexual orientation and identity.


With its focus on developing key technologies that are vital for the future and enabling the commercial utilization of this work by business and industry, Fraunhofer plays a central role in the innovation process. As a pioneer and catalyst for groundbreaking developments and scientific excellence, Fraunhofer helps shape society now and in the future.
