Leti and LTM have developed a new class of thin-layer composites for microelectronics. The composites are made by dispersing a very high load—more than 50% of the total volume—of nanoparticles in a polymer matrix. The resulting composite delivers unrivalled properties: virtually loss-free magnetic materials up to 20 GHz, a frequency 20 times higher than the norm.
Individual nanometric graphene shells protect the nanoparticles from oxidation. The distance between particles (and, therefore, the desired properties) is controlled by a second nanometric polymer shell. Nanocomposites were successfully implemented in layers up to 20 microns thick on 200 mm wafers in the clean room.
