Methods of fabricating organic thin film transistors

InactiveUS20120122275A1Suppresses and eliminates adverse effectSuppress and eliminate degradationSolid-state devicesSemiconductor/solid-state device manufacturingOrganic structureSemiconductor materials
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.

Orthogonal Procesing of Organic Materials Used in Electronic and Electrical Devices

An orthogonal process for photolithographic patterning organic structures is disclosed. The disclosed process utilizes fluorinated solvents or supercritical CO2 as the solvent so that the performance of the organic conductors and semiconductors would not be adversely affected by other aggressive solvent. One disclosed method may also utilize a fluorinated photoresist together with the HFE solvent, but other fluorinated solvents can be used. In one embodiment, the fluorinated photoresist is a resorcinarene, but various fluorinated polymer photoresists and fluorinated molecular glass photoresists can be used as well. For example, a copolymer perfluorodecyl methacrylate (FDMA) and 2-nitrobenzyl methacrylate (NBMA) is a suitable orthogonal fluorinated photoresist for use with fluorinated solvents and supercritical carbon dioxide in a photolithography process. The combination of the fluorinated photoresist and the fluorinated solvent provides a robust, orthogonal process that is yet to be achieved by methods or devices known in the art.
