Abstract: An electronic device protected by a novel barrier layer is provided. The barrier layer can protect against contamination and degradation arising from many sources, including oxidation and moisture. The barrier layer includes a barrier material that can include oxides, carbides, and compositions of sodium, aluminum, and fluorine.

Abstract: A system and method is presented for deposing a liquid on a substrate. The print head of an ink-jet printer emits a liquid containing ink and at least one other component. An energy beam, such as a laser, with sufficient intensity substantially causes at least a partial modification, such as evaporation, of a component of the liquid, thereby altering the drying profile. The ink deposed on the substrate may be used to create devices such as organic transistors and OLEDs.

Abstract: Systems and methods are described for delivering droplets. One embodiment provides a system comprising nozzles adapted to deliver droplets to target points on the substrate, a first camera, and means for determining an angular rotation of the substrate in a coordinate system. In some embodiments the means for determining the angular rotation includes a second camera. The substrate has a top surface and alignment marks. The nozzles have droplet delivery openings oriented towards the substrate for delivery of the droplets. The first camera is oriented substantially towards the nozzle openings, and the second camera is oriented substantially towards the substrate top surface.
