Abstract

See full text

An aim of the present invention is to reduce manufacturing costs and lower the electrical resistance of composite metal electrodes while lowering the contact resistance of the composite metal electrodes with respect to an organic semiconductor film. A TFT (semiconductor device) of the present invention includes an organic semiconductor film formed from an organic semiconductor material, and a source electrode and a drain electrode that are composite metal electrodes that contact the organic semiconductor film. The source electrode and the drain electrode are configured such that a low-resistance metal material that makes ohmic contact with the organic semiconductor film, the contact resistance thereof being lower than that of a base metal material formed of a metal material, is mixed with the base metal material, and the low-resistance metal material is disposed so as to be exposed at least at a contact surface with the organic semiconductor film.
