Contexte initial

There is an increasing demand for tools to rapidly synthesis complex new materials (e.g. metallic glasses or high entropy alloys that include many elements) by means of combinatorial thin film libraries. The microstructure of such materials is dependent upon deposition temperature, which is thus also a parameter to be optimized. COMBIMAT extends the number of elements and temperatures that can be screened at once, compared to the competition.

But

The project goal is to develop, and validate a new type of physical vapour deposition (PVD) system that uses an original multi beam sputtering (MBS) technology to do multicomponent, multilayer and high quality thin films combinatorial libra

Résultat

The BFH contribution to the project is related to the design of an innovative sample holder, consisting of high precision moveable apertures and a stage with micro-heaters together with software to guide an efficient statistical Design of Experiment (DOE) approach to the material discovery process.

Perspectives

COMBIMAT will commercialise a tool for material discovery via deposition of combinatorial material libraries by combining a physical vapour deposition system with a unique multi-temperature sample holder and a motion programmable mask.
