Tip-based Nanofabrication for NEMS Devices

Nano-electro-mechanical systems (NEMS) have been extensively studied and widely used in a variety of fields, for its ultrasensitive performance and enabling cutting-edge researches at this minuscule scale. However, existing nanofabrication still suffers from high cost or the difficulty of scaling up. This chapter gives an overview of currently widely employed nanofabrication techniques and then highlights one promising nanofabrication method based on scanning probes—tip-based nanofabrication (TBN). Finally, we conclude on the three major trends of current TBN technology development.
