Many applications in micro and nanotechnologies require micron-sized components, capable of positioning in ranges of sub-micrometers to a few microns. This paper reports on the design, fabrication and characterization procedure of an electrostatically actuated polymeric Nano-precision micro z-stage. Due to its ease of fabrication and great variety of functionalities, polymers have become an important material in micro fabrication technology. In contrast to piezoelectric stages, polymeric micro stage has a comparatively simple and cost effective fabrication procedure. Furthermore, low Young's Modulus of polymers made them a suitable basic material in comparison with their traditional counterparts. In this paper, SU-8 photoresist was used as the construction material and the photolithography technique were used to realize the stage. SU-8 with its low Young's modulus (5 GPa), has a higher tendency for bending, compared to, for example, silicon nitride (150-350 GPa). These properties make the SU-8 polymer, suitable for various applications.
