Leti 3S "Silicon Speciality Solutions"

Leti 3S is Leti's wafer service offer enabling any customer, from start-up to large corporation, to validate a proof of concept, a demonstrator in small quantities by implementing the appropriate tools available on Leti's platforms. To do this, the customer simply needs to provide a GDS file of its design and its process flow.

Leti then adapts this process flow to its cleanroom tool set, which often involves some tweaking. Any changes are made with the customer's agreement and pathfinder batches can be run to validate process integration. Further batches can be run to fine-tune the design and process flow until they are ready for transfer to a fabrication foundry, which will execute industrial and commercial production of the component.

Major achievements

Leti 3S' major achievements currently include suspended micro-channel resonators for MIT,  several micro-cooling devices for CERN's Large Hadron Collider. We have also developed neural probes for Caltech (California Institute of Technology) as part of the BRAIN Initiative.
