Printed organic electronics


Organic thin film transistors (OTFTs) have received interest in recent years for their potential as a low-cost alternative to amorphous silicon thin film transistors (TFTs) for electronic applications (Dimitrakopoulos and Mascaro, 2002; Katz, Bao, and Gilat, 2001). OTFT-based circuits are particularly suited for large-area devices, such as active matrix displays, where high switching speed is not required; they may also be attractive for low-cost microelectronic devices such as radio frequency identification (RFID) tags where the high cost of packaging silicon circuits becomes prohibitive. To produce low-cost OTFTs requires shifting from inorganic semiconduction processing paradigms— epitaxial wafers, photolithography, and vacuum deposition—to a new set of fabrication methods— rolled plastic substrates, print patterning, and solution-based deposition.
