|1. (WO2017038944) ORGANIC THIN-FILM TRANSISTOR, ORGANIC THIN-FILM TRANSISTOR MANUFACTURING METHOD, ORGANIC SEMICONDUCTOR COMPOSITION, ORGANIC SEMICONDUCTOR FILM, AND ORGANIC SEMICONDUCTOR FILM MANUFACTURING METHOD|
|Title:||ORGANIC THIN-FILM TRANSISTOR, ORGANIC THIN-FILM TRANSISTOR MANUFACTURING METHOD, ORGANIC SEMICONDUCTOR COMPOSITION, ORGANIC SEMICONDUCTOR FILM, AND ORGANIC SEMICONDUCTOR FILM MANUFACTURING METHOD|
The present invention addresses the problem of providing the following: an organic thin-film transistor that demonstrates high carrier mobility and low threshold voltage, and that excels in heat resistance; an organic thin-film transistor manufacturing method; an organic semiconductor composition; an organic semiconductor film; and an organic semiconductor film manufacturing method. This organic thin-film transistor includes, on a substrate, the following: a gate electrode; an organic semiconductor layer that contains an organic semiconductor compound; a gate insulation layer disposed between the gate electrode and the organic semiconductor layer; and a source electrode and drain electrode which are disposed in contact with the organic semiconductor layer and which are connected via the organic semiconductor layer. The organic semiconductor layer comes into contact with a block copolymer layer formed of a block copolymer, or further contains a block copolymer. The organic semiconductor compound has a molecular weight of at least 2000, and includes a repeating unit represented by formula (1).
