Abstract: A metallic nanoparticle composition dispenser includes a piston-cylinder assembly and a capillary tube. The piston-cylinder assembly includes a cylinder, a pneumatic port at first end of the cylinder, an outlet port at a second end of the cylinder opposite the first end, and a piston movable in the cylinder between the first end and the second end. The capillary tube has a tube inlet and a tube outlet, with the tube inlet being coupled to the outlet port of the cylinder. A metallic nanoparticle composition is contained in the cylinder. The metallic nanoparticle composition dispenser is configured such that the metallic nanoparticle composition is extruded by the piston through the capillary tube under pneumatic actuation by a regulated pneumatic system coupled to the pneumatic port.

Abstract: A method of forming an electrically conductive feature traversing a microscopic step on or in a substrate is disclosed. A metallic nanoparticle composition is continuously extruded from a capillary tube (nozzle) while displacing the capillary tube along a first portion of a trajectory from a first position (above a step-top portion) past an edge of the microscopic step to a second position to form a first extrudate. The composition is continuously extruded while displacing the nozzle along a sloped second portion of the trajectory from the second position to a third position (above a step-bottom portion) to form a second extrudate. The third position is at a lower height than the second position. The composition is continuously extruded while displacing the nozzle along a third portion of the trajectory from the third position to a fourth position (above the step-bottom portion). The feature includes the first, second, and third extrudates.

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.

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.
