Abstract:
1. 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 an organic semiconducting composition consists essentially of an N,N-dicycloalkyl-substituted naphthalene diimide and a polymer additive comprising an insulating or semiconducting polymer having a permittivity at 1000 Hz of at least 1.5 and up to and including 5, and exhibits a field effect electron mobility that is greater than 0.001 cm (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 thin film of the organic semiconducting composition, and, (c) forming a gate electrode spaced apart from the organic semiconducting composition, wherein the N,N-dicycloalkyl-substituted naphthalene diimide is present in the organic semiconductive composition in an amount of at least 50 weight % and up to and including 95 weight %, based on total organic semiconductive composition solids, and the N,N-dicycloalkyl-substituted naphthalene diimide is represented by the following Structure (II): wherein R the N,N-dicycloalkyl-substituted naphthalene diimide is represented by one of the following Structures (IIIa), (IIIb), (IVa), and (IVb): wherein R
