Crystal Device Technology 18 rue Alain Savary BESANCON - FRANCE Tel : Fax : Our future lies into the intelligence of materials…. Ferroelectric development – Innovative micro components

Marc BOUVROT-PARRATTE – CEO WS ICAN – C ONFIDENTIAL  Franche-Comté : historical know-how in watchmaking and microtechniques (close to Switzerland)  TEMIS Innovation:  Microtechniques Centre  Incubator  Technological Centre - MIMENTO (1000m²)  University of Franche-Comté  FEMTO-ST Institute – Regional Research Laboratory “The Franche Comté region is the cradle of microtechniques. Professions dealing with smallness and precision have long been part of its history and genes. Let’s not forget that this is where the watch was born.“  FEMTO-ST Spin-off Created in May 2011  4 employees  Applications fields  Optic (micromodulation, LASER, Imaging…)  Piezo (Sensors, actuators, Energy Harvesting…)  Technological facilities (Clean room processes…) H ISTORY AND C ONTEXT C RYSTAL D EVICE 2 / 8

Marc BOUVROT-PARRATTE – CEO WS ICAN – C ONFIDENTIAL O UR MISSIONS  Bring technical solutions adapted to our customers Due to our particularly efficient welding process to fix active materials on passive substrate (Glass or Silicon) with a perfect flatness control  Develop and produce tailored microcomponents prototypes From the bulk material to the final packaged prototype  High coefficients materials processing Our technology leads to produce high coefficients ferroelectics based micro components with a size improvement by a factor of 40.  Cleanroom facilities for ferroelectrics We are able to take in charge several steps of clean room processes (Mask creation, photolithography, surface treatment, material processing…) 3 / 8
