MIMENTO : Engineer in clean room technology, specialized in electronic lithography (M/W)

Context : The FEMTO-ST research institute in Besançon (www.femto-st.fr) is recruiting an engineer in clean room technology. The engineer will work within the MIMENTO technology center of FEMTO-ST, a member of the CNRS national network of 5 large academic centers dedicated to micro-nanotechnologies. He/She will join a team made up of engineers, researchers and doctoral students working in the MIMENTO clean room and will work under the responsibility of the manager of the nanotechnology resource

Missions: The main mission of the recruited engineer will be to develop new processes in electronic lithography. After a period of familiarization, he/she will also be required to invest more in the electronic lithography system: carrying out processes for academic or industrial customers, monitoring the system and training users. Depending on the current projects and on the candidate's areas of expertise, he or she may also work on other equipment in the nanotechnology resource, particularly in scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) or focused ion beam (FIB) fabrication.

Skills :

- General knowledge of physics, engineering sciences and/or materials science,
- General knowledge of the techniques involved (microfabrication processes, properties of materials in thin layers, etc.),
- Ability to found his work on an existing base (bibliography, laboratory processes, exchange with users),
- Ability to work in a team and independently,
- Analytical spirit, rigor and patience,
- English: Written and oral comprehension: level 2 - Written and oral expression: level

Contrat period : 12 months renewable


TF : Clean room process engineer/researcher for development of volume and surface acoustic wave devices

Context : The FEMTO-ST institute (Franche-Comté Electronic Mechanical Thermal and Optical – Sciences and Technologies, UMR 6174), is a mixed research unit, placed under the main supervision of the National Center for Scientific Research (CNRS) and the Bourgogne Franche-Comté University (UBFC) as well as the University of Franche-Comté (UFC), the École Nationale Supérieure de Mécanique et des Microtechniques (SUPMICROTECH-ENSMM) and the Belfort-Montbéliard University of Technology (UTBM). The Institute's strategy is to develop scientific research of excellence with a socio-academic and socio-economic impact based on a collective and responsible dynamic. Today it has more than 750 members, common services and seven departments, including the Time-Frequency department. Within the Time-Frequency department, the Micro-Acoustic Components and Systems (CoSyMA) team focuses its research on applications around frequency sources, filters and elastic volume and surface wave sensors. The candidate will work in close partnership with scientists from the FEMTO-ST Institute and will benefit from the facilities and expertise of the MIMENTO technology center.

Domain : microfabrication, clean room, acoustic wave devices

Job obtective :
The mission aims to develop the technology of frequency sources based on High Bulk Acoustic Resonator type volume wave resonators and surface wave resonators on composite substrate. This involves developing technological sectors and their sustainability to produce resonators with low sensitivity to the effects of temperature and vibrations. The encapsulation of these resonators will be addressed with a “wafer level packaging” approach and/or integration into a ceramic package. The characterizations necessary for the functional demonstration will be carried out by the candidate. A valorization of the work is requested either by filing a patent or publication in rank A journals
