Nanoark uses photolithography to etch nano-scale images onto silicon discs.This technology allows us to place thousands of images of scanned documents onto a single silicon wafer, in a format that can be retrieved either optically or digitally, and which can last for hundreds of years.  Waferfiche™ Technology meets or exceeds all specified microfilm standards and more as listed in our Waferfiche™ Standards section.
