DPN, a scanning-probe based lithography in which an AFM tip is used to generate nanoscale chemical patterns by directly transferring molecules to a surface, offers a number of realized and potential advantages over other nanofabrication methods. The greatest challenges in performing parallel probe lithography include fabricating large arrays of sharp tips, developing simple and widely accessible tip-surface alignment protocols, maintaining tip feedback, patterning a wide variety of molecules, and characterizing large arrays of nanostructures. Herein, we demonstrate parallel probe DPN in a high-throughput fashion using as many as 250 tips operating in parallel and covering a surface area with dimensions on the centimeter scale. |
