Megasonic cleaning systems and methods of fabricating and using the same are provided. In one embodiment, the system comprises a plurality of Micro-Electromechanical System (MEMS) transducers, each transducer including a movable membrane with a membrane electrode coupled to a first potential disposed above and spaced apart from an upper surface of a die including a cavity electrode coupled to a second potential, the membrane including multiple layers including a polysilicon layer between a top silicon nitride layer and a bottom silicon nitride layer, and the membrane electrode includes the polysilicon layer; a chuck on which a target workpiece is positioned; and a fluid to couple sonic energy from the plurality of MEMS transducers to the target workpiece. Other embodiments are also provided.
