Patent ID: 7989143

Claim:
A method of manufacturing a semiconductor device comprising the steps of: forming a lower electrode above a substrate; forming an insulating film so as to cover the lower electrode; selectively forming source and drain electrodes on the insulating film; and selectively forming, on the insulating film, a channel portion comprising an organic semiconductor so as to be put between the source and drain electrodes, with one end thereof being in contact with the source electrode and the other end thereof being in contact with the drain electrode; wherein the source and drain electrodes are formed by depositing a photosensitive self-assembled monolayer on the insulating film, irradiating exposure light to a predetermined region for forming the source and drain electrodes, rinsing the photosensitive self-assembled monolayer after irradiation using an aqueous organic alkali solution and water so as to increase a difference of water contact angle between portions of the photosensitive self-assembled monolayer that are exposed to the exposure light and not exposed to the exposure light, and then depositing a solution containing a conductive material on the insulating film, wherein during said rinsing neither the exposed portions or the unexposed portions is removed.
