Dip Pen Nanolithography

Dip Pen Nanolithography

The Nscriptor DPN System is a lithography system developed by Nanoink for patterning surfaces using “molecular ink.”  Dip Pen Nanolithography is NanoInk’s patented process for deposition of nanoscale materials onto a substrate.  The vehicle for deposition can include pyramidal scanning probe microscope tips, hollow tips, and even tips on thermally actuated cantilevers.

DPN process

Key Features:

  • Integrated DPN Patterning and Imaging in contact and AC modes.
  • Nanoscale Registry and Alignment: Write what you want to write, where you want to write it, and image it.
  • Precise and Accurate Lithography achieved through closed loop linearization of the piezo scanner.  Flexible samples and experiments enabled by scanning tip SPM design.
  • Repeatable experimental conditions achieved via software-controlled Environmental Chamber and vibration isolation air table.
  • Automated InkCal™ Calibration Routine to model ink diffusion and control feature size.
  • Sophisticated DPN pattern designs enabled by customized InkCAD™ tool.
