History and Mission

Beat De Coi created the company in 2006. They started out producing safety optical sensors or light curtains which stop doors from closing on people in elevators and automatic doors. They were finding it difficult to find suppliers for the semiconductor chips they needed so they decided to make their own. Now the company are a world-class photonics chip designer and manufacturer. Their production is in three areas. Making unique products such as light curtains and 3D cameras, customer projects and the foundry business in wafer fabrication. The wafer fab is built deep into a Swiss mountain which provides the isolation against vibration and temperature needed during the lithographic process. It is the ideal cocoon in which to operate IC manufacturing. They have created a specific TOF (Time of Flight) academy where they can train engineers in the 3D imaging systems of the future.

Career Sectors
