Development of parallel dip pen nanolithography probe arrays for high throughput nanolithography Conference Paper uri icon


  • Dip Pen Nanolithography (DPN) is a lithographic technique that allows direct deposition of chemicals, metals, biological macromolecules, and other molecular "inks" with nanometer dimensions and precision. This paper addresses recent developments in the design and demonstration of high-density multiprobe DPN arrays. High-density arrays increase the process throughput over individual atomic force microscope (AFM) probes and are easier to use than arrays of undiced commercial probes. We have demonstrated passive arrays made of silicon (8 probes, 310 m tip-to-tip spacing) and silicon nitride (32 probes, 100 m tip-to-tip spacing). We have also demonstrated silicon nitride "active" arrays (10 probes, 100 m tip-to-tip spacing) that have embedded thermal actuators for individual probe control. An optimization model for these devices, based on a generalized multilayer thermal actuator, is also described.
