  • Patent number: 8614441
    Abstract: Disclosed is a method for forming banks during the fabrication of electronic devices incorporating an organic semiconductor material that includes preparing an aqueous coating composition having at least a water-soluble polymer, a UV curing agent and a water-soluble fluorine compound. This coating composition is applied to a substrate, exposed using UV radiation and then developed using an aqueous developing composition to form the bank pattern. Because the coating composition can be developed using an aqueous composition rather than an organic solvent or solvent system, the method tends to preserve the integrity of other organic structures present on the substrate. Further, the incorporation of the fluorine compound in the aqueous solution provides a degree of control over the contact angles exhibited on the surface of the bank pattern and thereby can avoid or reduce subsequent surface treatments.

  • Patent number: 8134145
    Abstract: Disclosed is an organic electronic device, in which a semiconductor layer and source/drain electrodes may be formed from materials of the same type, suitable for a room-temperature wet process, and thus have surface properties similar to each other, thereby decreasing contact resistance between the semiconductor layer and the source/drain electrodes. The materials for formation of the semiconductor layer and source/drain electrodes may be organic semiconductor type materials obtained by adding carbon-based nanoparticles to organic semiconductor materials in predetermined or given amounts. As such, the conductivity of a semiconductor or conductor may vary depending on the amount of carbon-based nanoparticles.

  • Patent number: 8097694
    Abstract: Disclosed are organic semiconductor thin films using aromatic enediyne derivatives, manufacturing methods thereof, and methods of fabricating electronic devices incorporating such organic semiconductor thin films. Aromatic enediyne derivatives according to example embodiments provide improved chemical and/or electrical stability which may improve the reliability of the resulting semiconductor devices. Aromatic enediyne derivatives according to example embodiments may also be suitable for deposition on various substrates via solution-based processes, for example, spin coating, at temperatures at or near room temperature to form a coating film that is then heated to form an organic semiconductor thin film. The availability of this reduced temperature processing allows the use of the aromatic enediynes derivatives on large substrate surfaces and/or on substrates not suitable for higher temperature processing.

  • Patent number: 8053761
    Abstract: Disclosed are methods of fabricating organic thin film transistors composed of a substrate, a gate electrode, a gate insulating film, metal oxide source/drain electrodes, and an organic semiconductor layer. The methods include applying a sufficient quantity of a self-assembled monolayer compound containing a live ion to the surfaces of the metal oxide electrodes to form a self-assembled monolayer. The presence of the live ion at the interface between the metal oxide electrodes and the organic semiconductor layer modifies the relative work function of these materials. Further, the presence of the self-assembled monolayer on the gate insulating film tends to reduce hysteresis. Accordingly, organic thin film transistors fabricated in accord with the example embodiments tend to exhibit improved charge mobility, improved gate insulating film properties and decreased hysteresis associated with the organic insulator.
