Let’s Go Oilers!

The world’s smallest NHL logo is fabricated by the nanotechnology community at the University of Alberta in support of the Edmonton Oilers!!!

Working in partnership with two Edmonton companies who are developing new nanoscale fabrication processes to support commercialization of made-in-Alberta technology for photonics, sensors, and nanomaterials, the nanoFAB took the opportunity to show pride in our Edmonton Oilers.  

Using a nanomaterial developed by Applied Quantum Materials, and nanoscale pattern correction methods developed by Applied Nanotools, we thought it would be fitting to re-create the logo we fabricated during the Oilers’ last playoff run…albeit at a much smaller scale.

Whereas the Oilers logo in 2006 was about the width of a human hair, the logo we made for this year’s Orange Crush is over 40× smaller: at only 2.4 µm in diameter, over 900 million of these logos could fit on top of a hockey puck.

Beyond showing team spirit, the fabrication of this logo highlights several of the unique capabilities available at the nanoFAB. The logo was fabricated via electron-beam lithography (EBL) with our Raith 150-TWO system, using AQM SIOX as the EBL resist—a made-in-Edmonton alternative to the ultra-high resolution hydrogen silsesquioxane (HSQ) resist. At such a small length scale, sophisticated pattern correction techniques must be used to ensure the fidelity of the design; this expertise was provided by engineers from Applied Nanotools, who use the same methods for their high-resolution silicon photonics service. Finally, the images of the logos were taken using our Zeiss Orion NanoFab Helium Ion microscope.
