Post-Doctoral student (M/F) “Surface acoustic wave filters in thin film technology for 5G”.

The postdoctoral student (M/F) will work within the framework of the IPCEI07 project (“Evaluation of an innovative Thin Film SAW type technology in order to create a European industrial sector for 5G radio-frequency filters”).

TF SAW (Thin Film Surface Acoustic Waves) technology, which appeared in 2019, is an attractive solution for filtering in high frequency bands in mobile communication (5G for example). However, it is complex and requires redefining the design methodology and manufacturing rules. The postdoctoral fellow (M/F) will work on the development of surface acoustic wave filters based on TF SAW technology. He will be particularly involved in all aspects of characterization of elementary components (delay lines and resonators) and filters. He will also participate in physical simulation and design tasks based on theoretical and numerical models available within the laboratory. This work within the AIMAN-FILM and ACOUSTICS teams of the IEMN will be carried out as part of a project associating the IEMN and STMicroelectronics within the framework of the IEMN-ST Joint Laboratory.

The Institute of Electronics, Microelectronics and Nanotechnology (UMR CNRS 8520 – https://www.iemn.fr/en/) is located in Villeneuve D'Ascq, near the city of Lille (France). With a total staff of more than 500 people, the institute has a broad area of ​​research activity ranging from physics to materials science, acoustics, micro and nanotechnologies. The work will take place both within the École Centrale de Lille in Villeneuve d'Ascq (where the AIMAN-FILM team is located) and in the JUNIA-ISEN building in Lille (where the ACOUSTICS team is located) . The position is located in a sector falling under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with regulations, that your arrival be authorized by the competent authority of the MESR.
