The BND Nano Dynamic Scanner can create and modify nanostructures through a range of techniques, including local oxidation nanolithography, nanoscribing and local heating. Simultaneous high-speed imaging enables close monitoring of the fabrication process, minimising rework.
Writing at the Nanoscale
The BND Nano Dynamic Scanner can write directly to surfaces using a number of different techniques. The image above demonstrates local oxidation nanolithography of a silicon surface. By implementing a conductive tip, a potential may be applied between the tip and the surface. This applied potential results in the production of silicon oxide which appears topographically higher than the silicon surface.
By moving the tip across the surface structures may be created. Specific structures, patterns, and designs can be automatically produced.
CASE STUDY I: LOCAL OXIDATION-BASED NANOLITHOGRAPHY
The video to below shows an example of nanolithography performed using the BND Nano Dynamic Scanner at 2 times speed. The resultant structure is a logo for the Interface Analysis Centre (shown in the image to the left).
This work was performed at the Interface Analysis Centre (IAC) at the University of Bristol.
