Abstract

A simple and economical way of patterning pentacene (see figure) for the fabrication of organic thin-film transistors (TFTs) is described. In this transfer patterning technique a pentacene film deposited on a patterned “rigiflex” mold is transferred to the surface of an insulating gate dielectric. The carrier mobility of such a TFT is shown to be similar to that of a reference device fabricated using a shadow-mask technique.
