In this work, fabrication of Micro Electromechanical Systems (MEMSs) by silicon Electrochemical Micromachining (ECM) technology is demonstrated. High aspect-ratio MEMS structures, with different shape and dimension, consisting of inertial free-standing masses equipped with comb-fingers and suspended by springs from the substrate were fabricated by exploiting advanced features of the ECM technology. ECM fabrication of MEMS structures is here investigated and discussed.
