Microfabrication, News

We have developed a specific technology allowing to obtain thin monocrystalline custom layers transferred on plates of diameter up to 4 inches.

Our innovative manufacturing process has many advantages such as the conservation of the properties of materials and the modularity of stacks by the choice of materials (crystals, metals or polymers), their thicknesses (from a few microns to several hundred microns) and of their bonding interfaces (metallic or insulating).

Our custom hybrid substrates

Thin monocrystalline films on electrode or insulator

Support materials and thin layers customizable from piezoelectric materials (quartz, PZT, LiNbO3, etc.), optics (glass, KTP, BSO, etc.), semiconductors (silicon) and other materials on request.

SPECIFICATIONS

Wafer size: from sample to 4 inch diameter plates
Useful surface > 98%
Bonding strength > 25MPa
Layer thickness: from 1µm to a few hundred microns.
Number of layers in the stack: 1 to 10

APPLICATIONS

Radio-Frequency: Resonators, sensors, filters…
Photonics: laser, electro-optical sensors…
MEMS: actuator, sensor…
