Fabrication of any device requires patterning and this patterning for organic devices such as OTFTs presents a challenge because of the deleterious effects a solvent typically used in conventional lithography can cause. Particularly in the context of low cost, large volume manufacturing, there is a need to demonstrate that inexpensive material deposition and patterning processes can be integrated with existing device concepts with adequate performance. As an alternative to the vacuum deposition and photolithographic patterning of the various functional films, the use of high-resolution patterning techniques is of particular interest. We report simple microcontact printing techniques to form organic source/drain microstructure for organic thin film transistors (OTFTs). Fabrication of OTFTs with micron feature sizes demonstrates the approach. The performance of these transistors compares with that of similar devices constructed using conventional methods and Au source/drain.
