Nanotechnology Students Make World's Smallest Images of Stephen Colbert
The world's smallest images of Stephen Colbert were made by two undergraduate nanotechnology engineering students. John Maier and Erin Bedford fabricated four micro sized images of Stephen Colbert in a clean room at the University of Waterloo.
A layer of chrome metal was deposited on a blank wafer followed by a silicon nitride (SiN) layer, grown using plasma-enhanced chemical vapor deposition (PECVD). The SiN layer was then dry etched using reactive-ion etching (RIE). A layer of aluminum was then deposited on the wafer using sputtering and treated, completing the wafer fabrication. Lithography techniques were used throughout the process to generate the designed patterns.
