Drawing of a spiral delay line heater element, designed with the CNST Nanolithography Toolbox software
A recently developed CNST software package that designs difficult-to-draw nanoscale shapes, including spirals, S-bends, and tapered structures is now available online.
Dubbed the Nanolithography Toolbox, the software includes a library of more than 400 shapes and enables researchers to custom design curved structures of arbitrary complexity. There is no charge to use the software, which is described in the Journal of Research of the National Institute of Standards and Technology.
