About MagnetFab
MagnetFab, based in Grenoble (France), manufactures high-performance permanent micromagnets directly at wafer level. For this purpose, the established processes of semiconductor manufacturing are used: thin-film deposition and lithographic patterning of the magnetic rare-earth material NdFeB (neodymium-iron-boron). This makes permanent magnets available for the first time as a scalable semiconductor component, instead of being individually mounted as discrete components. MagnetFab offers custom prototyping of wafer-level micromagnets, from initial samples to a production-ready solution. The first application is a magnetic MEMS loudspeaker that is about five times smaller than a conventional loudspeaker and frees up approximately 80 % of the loudspeaker volume. Target industries are audio/electronics (earbuds, smartphones), magnetic sensing, medtech, quantum technologies, automotive and data centers.
