A piezoelectrically driven, submicron -positioning stage with multiprocess capability is developed and then integrated into two micro∕nanoscale manufacturing processes to improve their performance. The design is based on the HexFlex™ mechanism but is modified to improve structural robustness using a combination of factorial design, linear programming, and finite element analysis. Performance analysis reveals travel ranges of (-axis) and (-axis), positioning accuracies of (-axis) and (-axis), and overall stiffnesses of (-axis) and (-axis). A comparison of microfluidic channels manufactured with a micromachine tool (mMT) alone and with the stage stacked on the mMT shows an improvement in feature accuracy from . The stage is integrated with an electrochemical deposition setup. Nanowire structures with sharp angles are fabricated. The diameter of these nanowires shows an improvement in uniformity by decreasing the standard deviation of diameter variation from .
