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.
