  • Patent number: 8187915
    Abstract: A process for fabricating a thin film semiconductor device includes the following steps, but not necessarily in the noted order. Firstly, a thin film of organic semiconductor material is deposited onto a substrate. This thin film of organic semiconductor material comprises organic semiconductor material that comprises one or more aryl dicarboxylic diimidazole-based compounds of claim 1 such that the film exhibits a field effect electron mobility that is greater than 0.005 cm2/Vs. Then, the process includes forming a spaced apart source electrode and drain electrode, wherein the source electrode and the drain electrode are separated by and electrically connected with, the n-channel semiconductor film. A gate electrode is then formed, spaced apart from the semiconductor material. One or more of the thin film semiconductor devices (or transistors) can be incorporated into an electronic device.
