Abstract

A novel approach to inking pen arrays that address the multiplexed inking challenge in the context of DPN and related nanolithographies was investigated. Pattern sizes were measured by in situ lateral forces microscopy (LFM) of the MHA patterns, by examining the raised gold structures through optical microscopy, and also by AFM. Inkjet printing was carried out using a drop-on-demand microdispensing system with an 85-μm piezoelectric controlled nozzle that dispenses 320 pL droplets. The droplet formation was controlled by adjusting the voltage and pulse-width dispensing conditions, which could be monitored in real time using a charge-coupled device (CCD) camera. Ink solutions included MHA in ethanol, DOPC phospholipids in water and saturated MHA-acetonitrile solutions. It was observed that the inkjet and self-correcting inking strategy provide a versatile and high-resolution method of addressing the multiplexed-inking challenge for DPN with 1D and 2D cantilever arrays.
