Job description

Silicon detectors with internal amplification, such as Silicon Photomultipliers (SiPMs), are currently of great interest in several scientific, medicine and industrial applications, exploiting their extremely high sensitivity and the excellent single-photon time resolution. SiPMs are being evaluated for the detection of light signals in the vast majority of big science experiments planned for the future, from the HL-LHC upgrades (CMS, LHCb) to future Dark Matter, Neutrino and rare-event detection experiments (DarkSide, DUNE, nEXO), but also in commercial applications (nuclear medicine, such as PET, space and automotive LiDAR applications). In this fields, FBK is at the forefront of developments, collaborating with CERN and several other research institutions, in the scientific sector, and with important companies, for commercial applications. To further improve SiPM performance in the next generations of devices, technologies such as Through Silicon Vias (TSVs) and Back Side Illumination (BSI) of devices will be applied to SiPMs in the coming years. FBK is currently undergoing a clean-room upgrade to acquire microfabrication capabilities in this fields and a significant part of the job that the Reseacher will do will be related to these activities.

In this context, we are looking for a Device Engineer who will work on the development and characterization of next generation low-level light sensors, such as single photon avalanche diodes (SPADs) and Silicon Photomultipliers (SiPMs), and their integration with TSV and BSI technologies.
The researcher’s tasks will be:
  • to understand and improve device properties through TCAD simulations, process tuning and detector design;
  • to conceive new technological solutions, new process flows and integration schemes, in particular related to TSVs and BSI devices;
  • to carry out in depth, advanced functional characterization of SiPMs, including characterization of the detectors in a setup as close as possible to the final experiment / industrial application;
  • to manage interactions and relations with scientific experiments and / or industrial partners, to better understand the specifications and tune the SiPM characteristics accordingly.

The activity will be carried out in tight collaboration with other device and process researchers, working in a highly motivated, team-oriented environment. Significant publication output is expected. If selected, the candidate will have the opportunity to work and acquire know-how on one of the currently most innovative and rapidly evolving radiation detector technology, the SiPM, which is of great interest for both science and industry.
