Electrostatically actuated nanoscale tweezers are fabricated on micro processed electrodes using FIB-CVD. Heavily doped electrode works as interconnection platform for controlling nanoscale devices. Short bent pillars are deposited to control the gap distance of main tweezers fabricated on bent ones. Two types of tweezers which have different gap distances are fabricated and tweezing motion was successfully demonstrated. The threshold voltages at snap-down of the pillars are dependent on the initial gap distance of the unactuated pillars, and the measured values were 93V for 3.6um and 30V for 2.2um. The dimension of nano tweezers and initial gap distances are controllable as demonstrated and we expect more complicated 3-dimensional shapes are also possible.
