The aim of this PhD thesis is to realize a bistable microswitch using integrated magnets. New designs of such micro-switches have been drawn in order to obtain both higher contact forces and lower commutation currents compared to such existing systems. Magnetic simulation softwares have been used to assess static and dynamic behaviour of the micro-switches. Then thick films (>1 µm) of high performance hard magnetic materials (NdFeB, SmCo) have been deposited with triode sputtering, which enables high deposition rates on large areas. Conditions of sputtering and heat treatments were studied to get high coercivities, high remanences and special textures. Basic technological steps have been developed to integrate these magnetic films into a mi...
