Organic thin film transistor and manufacturing method thereof

摘要

An OTFT is provided which is characterized by including a substrate (10) having therein a groove and one of a groove and a hole, a source electrode (15) filling the one of the groove and the one of the groove and the hole, a drain electrode (14) filling the other one of the groove and the one of the groove and the hole, a film (13) of organic semiconductor material formed on the source electrode (15) and the drain electrode (14) for making electrical contact therewith, a gate insulating film (12) formed on the film (13) of organic semiconductor material, and a gate electrode (11) formed on the gate insulating film (12). A method of manufacturing the OTFT allows realization of high precision microfabrication of the source electrode (15) and the drain electrode (14) formed on the substrate (10) such as a plastic substrate (10) by an inexpensive process for stable realization of high performance.
