Abstract

A process to fabricate solution-processable thin-film transistors (TFTs) with a one-step self-aligned definition of the dimensions in all functional layers is demonstrated. The TFT-channel, semiconductor materials, and effective gate dimention of different layers are determined by a one-step imprint process and the subsequent pattern transfer without the need for multiple patterning and mask alignment. The process is compatible with fabrication of large-scale circuits. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
