Patent ID: 8105870

Claim:
A method for manufacturing a semiconductor device, comprising: forming a source electrode and a drain electrode on a substrate; forming an organic semiconductor layer including a π conjugated organic compound at least between the source electrode and the drain electrode; applying an application liquid on the organic semiconductor layer, the application liquid being made of a polymer of an alicyclic compound dissolved in a paraffin hydrocarbon solvent that is a carbocyclic compound without having aromaticity; forming a gate insulation layer including the polymer of the alicyclic compound by removing the paraffin hydrocarbon solvent from the application liquid; and forming a gate electrode on the gate insulation layer, wherein the alicyclic compound is one compound selected from the group consisting of: wherein R 1 and R 2 , respectively, indicate a hydrogen atom and an alkyl group having a carbon number of from 1 to 20, and m+n is in the range 10 to 100,000, and m can be zero.
