Abstract: An additive method of forming a metallic nanoparticle microdot on a substrate is disclosed. The method includes: (A) estimating or obtaining a position of an outlet of a capillary tube at zero height above the substrate (zero-height position); (B) extruding a metallic nanoparticle composition from the outlet at a first height h1 above the zero-height position, including forming a fluid bridge between the outlet and the substrate; (C) optionally lifting the capillary tube relative to the substrate by a height increment of Dh while continuing to extrude the metallic nanoparticle composition from the outlet; and (D) rapidly lifting the capillary tube to separate the outlet from the fluid bridge.

Abstract: A method of decreasing a sheet resistance of a transparent conductor is disclosed. The method includes the following: forming a first transparent conductor layer on a substrate; dispensing a metallic nanoparticle composition on the first transparent conductor layer to form metallic nanoparticle features; and sintering at least the first transparent conductor layer and the metallic nanoparticle features. The first transparent conductor layer includes a crystalline metal oxide. The aperture ratio of the transparent conductor is in a range of 90% to 99%.
A multilayer transparent conductor and a method of forming a multilayer transparent conductor are also disclosed.

Abstract: Fluid printing apparatus including substrate, print head, pneumatic system, and print head positioning system. The print head ejects fluid in a continuous stream with a micro-structural fluid ejector consisting of output, elongate input, and tapering portions between the output and elongate input portions. The output portion consists of an exit orifice of an inner diameter ranging between 0.1 μm and 5 μm and an end face having a surface roughness of less than 0.1 μm. The print head is positioned above the substrate with the output portion of the micro-structural fluid ejector pointing downward. During printing, the print head positioning system maintains a vertical distance between the end face and the printable surface of the substrate within a range of 0 μm to 5 μm, and the pneumatic system applies pressure to the fluid in the micro-structural fluid ejector in the range of −50,000 Pa to 1,000,000 Pa.

Abstract: A method of filling a microcavity with layers of a polymer material includes the following steps: (A) estimating a current vertical position of a bottom of the microcavity (current bottom position); (B) lowering the capillary tube into the microcavity towards the current bottom position; (C) dispensing a polymer composition from a tube outlet of the capillary tube under a dispensing applied pressure until the polymer composition substantially fills the microcavity; (D) curing a work piece including the microcavity and the polymer composition in the microcavity to obtain a current layer of the polymer material; and (E) repeatedly executing steps (A), (B), (C), and (D), until the layers of the polymer material have substantially filled the microcavity.
