High-Performance Thick On-chip Hard Magnets for MEMS Applications

We adopted two methods for thick on-chip hard magnets fabrication for MEMS application.(1) Dry packing of Nd 2 Fe 14 B powders. Nd 2 Fe 14 B powders were mixed with binder wax powders, then dry-packed into pre-etched trenches on silicon wafers under 10 MPa pressure and 100 C heating. An out-of-plane, in-situ magnetic field of 1000 Oe was applied during the process.(2) High pressure compression of Nd 2 Fe 14 B powders. Nd 2 Fe 14 B powders were packed into a metal mould and heated to 300 C with 850 MPa pressure applied. The sample was bonded onto the silicon chip with polyimide. The dry-packed Nd 2 Fe 14 B magnets showed a remanent out-of-plane magnetization of 330 emu/cc (B r= 0.42 T), a coercive field of 8.6 kOe (690 kA/m) and an energy product of 2.4 2. 6 MGOe (19-21 kJ/m 3). It is also found that the out-of-plane magnetic field can boost the remanent magnetization in that direction ……
