| Abstract | Thin-film transistors (TFTs) of polymeric semiconductors were fabricated using selective dewetting in the patterning process. The process consists of: (i) patterning the wettability of the substrate using a protective layer of printed wax and a self-assembled monolayer, and (ii) patterning a polymeric semiconductor by selective dewetting from an organic solution. The method has been used to fabricate small arrays of TFTs with a regioregular poly(thiophene) and poly(9-9(')-dioctyl-fluorene-co-bithiophene). The TFTs exhibited mobilities of 0.5-1.0x10(-3) cm(2) V-1 s(-1) and on-to-off ratios on the order of 10(4). (C) 2002 American Institute of Physics. |
