The method includes: forming an OFET pattern on a substrate, the OFET pattern having a gate electrode, a dielectric layer, a source electrode, a drain electrode, and an organic semiconductor layer; attaching a junction layer covered with a predetermined adhesive on the entire surface of the source and drain electrodes and the organic semiconductor layer and isolating the OFET pattern from the substrate; and transferring the isolated OFET pattern onto a plastic substrate that is prepared beforehand. In this method, the OFET pattern can be deposited without the temperature limit, the dielectric layer can be formed using a wide variety of materials, and the OFET pattern can be transferred in a very simple manner. Also, the junction layer functions as a passivation layer for protecting the organic semiconductor layer from external air and moisture so that the organic semiconductor layer can keep good performance for a long time.

Abstract: Disclosed is a method for manufacturing a conductive organic thin film device. An air-bridge type of an upper electrode is formed over a lower electrode by using a sacrificial layer and then a gap having a thickness of several nano meter is formed in a part at which the upper electrode and the lower electrode intersect by removing the sacrificial layer. The conductive organic molecules are uniformly adsorbed between the upper electrode and the lower electrode of the nano gap. Adsorption extent of the conductive organic molecules is confirmed by observing a current flowing through the upper and lower electrodes when the conductive organic molecules are adsorbed. Thus, reproducibility of a manufacturing process is improved and mass production is facilitated by adoption of a standardized process.
