Are you interested in developing the fabrication of photonic integrated circuits and looking for a new job opportunity in the field? Would you like to develop innovative technology with superb colleagues who are top experts in their field? Do you want to work at the interface of academy and industry using state-of-the-art research facilities? VTT might be just the place for you.
VTT is one of the leading applied research organisations in Europe. What unites us are curiosity, a passion for learning and a purpose: to solve the biggest challenges of our time and turn them into sustainable growth and well-being. Our cross-disciplinary community of over 2300 brilliant minds is focused on creating impact through science-based innovation. Get to know us further by exploring VTT’s tech & infra.
We are now looking for a Wafer Process Integrator to join our Silicon photonics team.
As a Wafer Process Integrator , you will develop fabrication technology for photonic integrated circuits (PICs) in close collaboration with our PIC designers, cleanroom operators and process engineers. Operators do most of the actual wafer processing in our cleanroom according to the processing instructions made by you. You will supervise the wafer processing and monitor the quality of the fabrication by various wafer-level inspections (microscopy, ellipsometry etc.) inside the cleanroom. You will also do some hands-on process development in critical process steps together with the process engineers, until the processes are mature enough to be given to our operators. Depending on your own skills and preferences, you may also get involved in the design and testing of the PICs, but your main focus will be on the fabrication of the PICs in our cleanroom. Process simulation and some simulation for active semiconductor components, such as Ge photodiodes, will be part of your work.
Our in-house PIC technology includes the design, fabrication, assembly, packaging and testing of components, circuits and systems that are based on optical waveguides integrated on small silicon chips. All these development steps can be done at VTT, including 200 mm wafer processing in our Micronova cleanroom facility in Espoo, although we also collaborate with many other organizations to do these tasks. Our Silicon Photonics team is one of the global pioneers in the development of PIC technology. We mainly focus on PICs that are based on silicon-on-insulator (SOI) or silicon nitride waveguides, while we often hybrid integrate these with other materials and PIC technologies, such as germanium, lithium niobate, graphene and III-V compound semiconductors. Your role in the team will mainly focus on the develop of SiN waveguides and Ge photodiodes, at least in the beginning. Our 3 µm thick SOI waveguides allow to make low-loss PICs for an extremely wide range of infrared wavelengths (1.2 – 4 µm), while the SiN waveguides extend the feasible wavelength range to visible wavelengths and support the development of multiple quantum computing technologies. We believe that PIC technology plays a key role in solving many global challenges (climate change, healthcare, power-efficient digitalization etc.), while also offering good business opportunities.
