Abstract:
Systems and methods are provided in which individual elements of a thin patterned film are deposited by two or more nozzles having different geometries. The different nozzle geometries may include one or more of different throttle diameters, different exhaust diameters, different cross-sectional shapes, different bore angles, different wall angles, different exhaust distances from the substrate, and different leading edges relative to the direction of movement of the nozzles or the substrate. Methods may include steps of ejecting a carrier gas and a material from a plurality of nozzles and depositing the material on the substrate in a plurality of laterally spaced elements, each of the elements deposited by a separate nozzle group. At least one of the nozzles in a group of nozzles depositing an element may be configured to deposit the material on the substrate in a width that is smaller than the width of the element.
