Patent ID: 8187915

Claim:
A process for fabricating a thin film semiconductor device, comprising, not necessarily in the following order, the steps of (a) depositing, onto a substrate, a thin film of organic semiconductor material that comprises an organic semiconductor material that comprises one or more aryl dicarboxylic diimidazole-based compounds such that the film exhibits a field effect electron mobility that is greater than 0.005 cm 2 /Vs; (b) 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; and (c) forming a gate electrode spaced apart from the semiconductor material, wherein the organic semiconductor material is a compound represented by one of the following structures: wherein Ar 1 and Ar 2 are the same or different, and are each carbocyclic or heterocyclic aromatic ring systems fused to each corresponding adjacent imidazole in the structure, wherein each of Ar 1 and Ar 2 are substituted with one or more fluorine atoms, X is an optional organic or inorganic substituent group at any available position on the core nucleus, n is zero or an integer from 1 to 8, and m is zero or an integer from 1 to 4.
