Abstract
A method for forming an organic electronic device, which method comprises the steps of: The method allows the formation of a device structure wherein the device layers to be patterned are self-aligned. The method enables a multiplicity of layers to be patterned in a single set of printing and lift-off steps using one pattern which ensures the excellent vertical alignment of edges, which would be difficult to achieve by direct printing. Horizontal alignment can also be achieved. The size of the device features can be reduced below the actual printing resolution. Examples of organic electronic devices include OFETs, OLEDs, memory, sensing elements, solar cells, photo-sensors, photoreceptors for electrophotography and the like.
