Post-processing techniques are applied after the integration and assembly of nanostructures and Microelectromechanical Systems (MEMS) to realize integrated Nanoelectromechanical Systems (NEMS). Experimentation is focused specifically on the application of post-processing steps to a locally self-assembled micro-to-nano system comprising of suspended silicon nanowires between two MEMS bridges. Local contact metallization, global metallization for rapid system functionalization and the application of aqueous treatment to the NEMS are among the post-processing techniques studied. These techniques are evaluated for their effectiveness and compatibility with integrated NEMS and traditional MEMS processes. It is found that local and global contact metallization techniques effectively alleviate inherent problems at the nano-to-micro contact and the aqueous treatment study confirms the effectiveness of the super critical drying process for nanostructures.
