MagnetFab introduces a new manufacturing capability by integrating permanent micromagnets directly at wafer level. This
breakthrough enables a new generation of magnetic microsystems for consumer electronics, sensing, medical and quantum
technologies.
For decades, permanent magnets have enabled essential functions inside electronic devices, from
speakers and sensors to medical equipment and electric motors.
As electronics continue to shrink, magnets have become one of the last components that cannot
be manufactured using semiconductor processes. This limitation is now a major obstacle to
further miniaturization and system integration.
MagnetFab manufactures high-performance permanent micromagnets directly at wafer level, using thin-film deposition and
lithographic patterning, the same manufacturing principles used by the semiconductor industry.
Our micromagnets are made from NdFeB, a rare-earth magnetic material used in the world’s strongest permanent magnets,
combining microscopic dimensions with exceptional magnetic performance.
A scalable, semiconductor-compatible approach to magnet manufacturing.
Earbuds are among the most highly integrated consumer electronic devices. As new features are added, internal complexity keeps increasing
while the form factor cannot grow.
The loudspeaker remains one of the largest components and a major constraint on further miniaturization.
This makes earbuds an ideal first application to showcase what wafer-level permanent micromagnets can enable.
Conventional loudspeaker technology
5X smaller
80% of the loudspeaker volume freed
For the first time, permanent micromagnets can be manufactured directly at wafer level using semiconductor-compatible processes. This introduces a new building
block for microsystems, enabling entirely new device architectures across multiple industries.
Our magnetic MEMS loudspeaker is just the beginning. By making permanent micromagnets available as a semiconductor building block, we aim to unlock new
possibilities across industrial, medtech, quantum and other emerging applications.
We provide custom wafer-level permanent micromagnet prototyping services for companies exploring integrated
micromagnets in MEMS, sensing and quantum applications.
They are tiny permanent magnets manufactured directly on semiconductor wafers. MagnetFab produces them with thin-film deposition and lithographic patterning, the same manufacturing principles used to make microchips. Magnets can therefore be integrated into MEMS devices and microsystems at scale, instead of being assembled one by one as discrete components. This approach brings the precision, repeatability and scalability of semiconductor manufacturing to magnetic functions.
MagnetFab uses NdFeB (neodymium-iron-boron), the rare-earth magnetic material found in the world’s strongest permanent magnets. Deposited as a thin film and patterned at wafer level, it combines microscopic dimensions with exceptional magnetic performance.
In earbuds, the loudspeaker is one of the largest components and a major constraint on further miniaturization. A magnetic MEMS loudspeaker built at wafer level is 5X smaller and frees 80% of the loudspeaker volume, leaving more room for the battery, sensors and new features. Device makers gain design freedom without increasing the size of the product.
Audio and acoustics is the first market. By making permanent micromagnets available as a semiconductor building block, MagnetFab also opens new device architectures in medtech, quantum technologies, automotive, magnetic sensing and other industrial applications.
