Abstract
A method of patterning soluble materials on a substrate is described. In the method, a stamp is applied to a liquid carrier solution. The raised areas of the stamp removes mainly a liquid carrier leaving behind a precipitate while the non-raised areas of the stamp lifts both the liquid carrier and the precipitate from the substrate. The result is a precipitate pattern residue that matches the raised area of the stamp. One use of the method is for patterning large areas of polymers used in large area electronics such as displays and sensors.
