Abstract
A film-forming composition according to the present invention include fluororesin having a repeating unit of the general formula (1); and a fluorine-containing solvent. In the general formula (1), Reach independently represents a hydrogen atom, a fluorine atom, a methyl group or a trifluoromethyl group; and Reach independently represents C-Cstraight, C-Cbranched or C-Ccyclic fluorine-containing hydrocarbon gr which any hydrogen atom may be replaced by a fluorine atom with the proviso that the repeating unit contains at least one fluorine atom. This film-forming composition is suitably usable for the manufacturing of an organic semiconductor element because the composition can form a film on an organic semiconductor film; and the formed film has resistance to an etching solvent during the fine pattern processing of the organic semiconductor film by photolithography etc.
