Permanent magnets are essential for many next-generation #microsystems. Integrating them at wafer level is the real challenge. This is exactly what #PowderMEMS®, the patented technology developed at Fraunhofer ISIT, was designed to solve. PowderMEMS enables the wafer-level integration of high-performance permanent micromagnets directly into silicon and glass substrates — compatible with pre-processed wafers and without complex post-assembly of discrete magnetic components. For developers of #quantum hardware, #MEMS and advanced #sensor systems, this opens new possibilities for system integration, miniaturization and performance. Key capabilities include: 🔹 Remanence Br up to 550 mT using NdFeB powders 🔹Temperature stability from 5 K to 420 K — from cryogenic quantum systems to demanding industrial environments 🔹 Low process temperatures below 100 °C, enabling integration into sensitive pre-processed structures 🔹 Custom magnetic field and gradient shaping at wafer level PowderMEMS has already been successfully applied in a wide range of microsystem technologies, including back-biased Hall sensors, AMR sensors, NV quantum sensors, ion traps for quantum computing and MEMS energy harvesters. As microsystems become more integrated and functionality moves directly into the substrate, magnetic components must evolve as well. PowderMEMS brings permanent magnetic functionality where conventional assembly approaches reach their limits. 🫱🏼‍🫲🏼 Interested in integrating permanent micromagnets directly into your microsystem architecture?
