PATTERNED DEPOSITION USING COMPRESSED CARBON DIOXIDE

WIPO Patent Application WO2002045868

A3

A method for the patterned deposition of a material comprises the steps of dissolving or suspending said material in a solvent phase comprising compressed carbon dioxide, and depositing the solution or suspension onto a surface, evaporation of the solvent phase leaving a patterned deposit of said material. This method is particularly suitable for the patterned deposition of polymers and small organic molecules in organic light emitting diodes and organic transistors.
