Several direct printing techniques may favor electronic applications of polymer semiconductors. Capillary-force lithography, aerosol, inkjet, and electrohydrodynamic (EHD) jet printing techniques easily deposit and pattern polymer semiconductors.6-9 Among these, EHD jet printing has proven to be particularly simple and inexpensive.10 This printing technique uses a high voltage between the nozzle tip and a substrate to generate a strong electrostatic field, which ejects ink from the nozzle, and can produce a variety of fine polymer semiconductor patterns.11-14 Therefore, because of the selective printing characteristics of EHD, the semiconductor can be printed at required locations, so this method can be used to print logic circuits |
