Abstract
Production of an electronic device by solution processing by depositing fluid including a device material or a precursor thereto onto a zone of a substrate surface between at least two opposed barriers for together controlling the spread of said fluid on the substrate surface, wherein at least one of the two opposed barriers is structured so as to facilitate controlled spillage of excess fluid out of the zone to one or more selected locations. Also, production of an electronic device by solution processing by longitudinally depositing fluid containing a device material or a precursor thereto on a patterned substrate to form a plurality of spaced longitudinal channels of said device material of controlled lateral width, wherein the substrate is patterned such that at least one lateral connection between at least one pair of adjacent channels is formed at at least one selected location without the need to carry out any lateral deposition of said fluid.
