摘要

We fabricated nanopatterns on Cu thin films via an electrochemical route using an atomic force microscope(AFM). Experimental results were compared with an equivalent electrochemical circuit model representing an electrochemical nanomachining(ECN) technique. In order to precisely construct the nanopatterns, an ultra-short pulse was applied onto the Cu film through the AFM cantilever tip. The line width of the nanopatterns (the lateral dimension) increased with increased pulse amplitude, on-time, and frequency. The tip velocity effect on the nanopattern line width was also investigated. The study described here provides important insight for fabricating nanopatterns precisely using electrochemical methods with an AFM cantilever tip.
