Low-temperature processable inherently photosensitive polyimide was prepared from a dianhydride, 3,3′,4,4′-benzophenone tetracarboxylic dianhydride, and aromatic diamines, 4,4′-diamino-3,3′dimethyl-diphenylmethane, through a polycondensation reaction, followed by a chemical imidization method. The photosensitive polyimide cured at 180 °C is used as a gate dielectric to fabricate flexible organic thin-film transistors with pentacene as an active semiconductor on polyethersulfone substrate. With the inherently photosensitive polyimide, the access to the gate electrode could be created easily without complicated and expensive lithographic techniques. A field effect carrier mobility of 0.007 cm2/V s was obtained for the pentacene organic thin-film transistors (OTFTs) with the photo-patterned polyimide as a gate dielectric. More detailed analysis for the pentacene OTFTs will be given with electrical properties of the thin polyimide film. Low-temperature processability and patternability of the polyimide give us more freedom to choose plastic substrates in OTFTs and facilitate the realization of low-cost organic electronics.

This work focuses on dielectric materials in organic thin film transistors. Silicon oxides whose surfaces are modified with hexamethyldisilazane (HMDS) and octyltriethoxylSilane (OTS) are investigated. Organic semiconducting materials are used in the transistors made within the scope of this work. Although the devices made using our procedures did not exhibit satisfactory performance, we explored and understood some chemical and engineering aspects of the relevant dielectric/semiconductor interfaces in organic thin film transistors. Understanding these systems would help with improvements of the electrical properties and performance of such systems when plastic substrates are used at the next stage of the project.
