    • 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.
    • 提供了系统和方法,其中通过具有不同几何形状的两个或更多个喷嘴沉积薄图案化膜的各个元件。 不同的喷嘴几何形状可以包括一个或多个不同的节流直径,不同的排气直径,不同的横截面形状,不同的孔角度,不同的壁角度,与基板的不同排气距离以及相对于运动方向的不同前缘 喷嘴或基板。 方法可以包括以下步骤:从多个喷嘴喷射载体气体和材料,并将材料沉积在多个横向间隔开的元件的基板上,每个元件由单独的喷嘴组沉积。 沉积元件的一组喷嘴中的至少一个喷嘴可以被配置为以小于元件宽度的宽度将材料沉积在基板上。
