Abstract
A manufacturing method of an organic semiconductor device including an organic semiconductor transistor formation process, wherein the process includes: an organic semiconductor layer formation step of using a substrate to form an organic semiconductor layer made of an organic semiconductor material on the substrate; a passivation layer formation step of forming pattern-wise on the organic semiconductor layer a passivation layer having an ability of shielding vacuum ultraviolet light and an organic semiconductor layer patterning step of irradiating vacuum ultraviolet light to the passivation layer and to the organic semiconductor layer to etch the organic semiconductor layer corresponding to a part where the passivation layer is not formed.
