Patent ID: 8658459

Claim:
A method of producing an organic semiconductor device, comprising: an organic semiconductor layer arrangement step of providing an organic semiconductor layer on a gate insulating layer of a substrate on which a gate electrode and the gate insulating layer covering the gate electrode are arranged; and an electrode arrangement step of providing a source electrode and a drain electrode on the organic semiconductor layer, the organic semiconductor layer arrangement step comprising: a precursor arrangement step of arranging a solution containing a bicyclo organic compound which is a precursor on the gate insulating layer; and a step of subjecting the bicycle organic compound to irradiation with light, wherein the bicyclo organic compound is a compound represented by the following general formula (9): where the B ring is represented by the following general formula (27), R 17 to R 22 are each independently one selected from the group consisting of a hydrogen atom, a hydroxyl group, a halogen atom, an alkyl group, an alkoxy group, an alkylthio group, an ester group, an aryl group, a heterocyclic group, and an aralkyl group, Z 1 to Z 4 are each selected from the group consisting of a nitrogen atom and CR 60 , and may be identical to or different from one another, wherein R 60 is one selected from the group consisting of a hydrogen atom and an aryl group, M represents two hydrogen atoms, a metal atom, or a metal oxide, and each pair of R 17 and R 18 , R 19 and R 20 , or R 21 and R 22 may be combined together to form the B ring; where R 54 to R 59 are each independently one selected from the group consisting of a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, a heterocyclic group, an aralkyl group, a phenoxy group, a cyano group, a nitro group, an ester group, a carboxyl group, and a halogen atom, R 58 and R 59 may be coupled with each other to form a five-membered heterocyclic ring or a six-membered heterocyclic ring, and n 5 and n 6 each independently represent an integer of 0 or more.
