Master Thesis - Development of high quality

Master Thesis - Development of high quality, densely packed filter pixel arrays using 3D lithography methods for color and spectral sensing applications (f/m/d)

Befristet, Vollzeit · VILLACH

Recent years have seen increasing interest in the development of optical sensors for smartphones, wearables, Internet of Things (IoT) and more. In particular, integrated solutions for spectrometry and multi-spectral imaging have gained much importance in today’s metrology. This trend applies for color and spectral sensors integrated on CMOS imagers (CIS). Yet, many fabrication challenges remain to be solved for the field to meet the industrial requirements regarding reliability, low-cost and high-volume production, while keeping the miniaturization ongoing.
In this regard, the definition of the filter arrays using nanoimprint lithography (NIL) could provide the utmost miniaturization and performance to the sensor. NIL requires the production of a high-quality mold beforehand, to proceed with the subsequent replication and imprint. 

In this proposed master thesis, the student will:
  • Develop the design and process flow of the fabrication of the NIL mold
  • Develop the lithography and etching process for the definition of the mold
  • Characterize the fabricated structures using advanced characterization tools
  • Perform data analysis and retrieve statistical variation of the manufactured structures
  • Apply the theoretical and experimental knowledge acquired during the internship to elaborate protocol and new concepts for the color and spectral sensors
  • Participate to scientific and knowledge dissemination: Scientific report, documentation, presentation, and paper writing
  • Master student in physics, photonics, microsystem technologies or similar field
  • Having a background in cleanroom environment, microsystems fabrication processes, tools, and materials
  • Experience with data processing, evaluation and visualization software or language (e.g. Matlab, Python)
  • Experience in a cleanroom environment
  • Hand-on experience with microfabrication process and tools
  • Experience with wave optics simulation software and/or CAD tools is valuable
  • Autonomy and good reporting skills
  • Good teamwork and good communication skills in English, German is an advantage
  • Diversified research activities with plenty of technical challenges.
  • State-of-the-art lab facilities and instruments.
  • Internal and external training opportunities for further development.
  • Home Office possible.
  • € 4 per day food allowance in restaurants or € 2 per day in supermarkets.
  • Family & kids friendly.
  • Free coffee/milk/tea & fresh fruits.
This position is subject to the Collective Agreement for employees in non-university research (Research CA) related to §19. For this position, we offer a salary of EUR 1.713,- paid 14 times a year.

Silicon Austria Labs (SAL) is a top research center for Electronic Based Systems (EBS). At three locations (Graz, Villach, Linz), SAL is conducting research along the entire EBS value chain in the areas of sensor systems, power electronics, RF (radiofrequency) systems, system integration and embedded systems to develop future-oriented solutions for industrial production, health, energy, mobility, safety and more. SAL brings together key players from industry, science and research and thus valuable expertise and know-how and conducts cooperative, application-oriented research along the value chain. Cooperative projects are co-financed by SAL and enable a fast and unbureaucratic project start. SAL is thus shaping the high-tech location Austria and Europe and developing the future 
Innovation is our top priority and so are our employees. We are a family-friendly company and support the compatibility of work and family as much as possible. That is why we have been awarded the Work and Family Certificate until 2023. But we are constantly working on new measures to offer our employees an environment where they feel good, healthy and motivated.
