Abstract: A method of obtaining a numerical model is disclosed. The numerical model correlates estimated line width values to minimum pressure for gas bubble generation (MPGBG) values. An MPGBG value of each capillary tube in the reference group is measured for a liquid. A nanoparticle composition is deposited, under standard conditions, on substrate(s) from each respective reference capillary tube, to form nanoparticle lines. A line width of each of the nanoparticle lines deposited using each respective reference capillary tube is measured by a microscope apparatus. A numerical model that correlates estimated line width values to MPGBG values for the liquid is calculated.

Abstract: A method of dispensing a metallic nanoparticle composition along a trajectory on a substrate is disclosed. The composition is dispensed from a nozzle through its outlet. The outlet is characterized by an outlet size. First, an initial pressure is applied to the composition in the nozzle to cause the composition to flow from the outlet. The nozzle is positioned at a height such that the composition does not flow onto the substrate. Second, the nozzle is lowered toward the substrate such that a fluid bridge forms between the outlet and the substrate and an adjusted pressure is applied to the composition in the nozzle. The adjusted pressure is lower than needed for the composition to continue to flow from the outlet. Third, the fluid is dispensed from the nozzle. A dispensing pressure is applied to the fluid while the nozzle is laterally displaced along the trajectory on the substrate.

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 obtaining a numerical model is disclosed. The numerical model correlates estimated capillary tube output diameter values to minimum pressure for gas bubble generation (MPGBG) values. An MPGBG value of each capillary tube in the reference group is measured for a liquid. An output diameter of each of the capillary tubes is measured by a microscope apparatus. A numerical model that correlates estimated capillary tube output diameter values to MPGBG values for the liquid is calculated.
A method of estimating an output diameter of a capillary tube includes the following steps. An MPGBG value of the capillary tube for a liquid is measured, and the measured MPGBG value is input into the numerical model to estimate the capillary tube output diameter value.
Other methods include a method of estimating an output diameter value of a capillary tube in a test group, a method of estimating and storing output diameter values of capillary tubes in a test group, methods of selecting at least one capillary tube from a plurality of capillary tubes in a test group, and a method of cutting a capillary tube to a desired estimated capillary tube output diameter value.

Abstract: A method for modifying an elongate structure including providing a fluid deposited onto the substrate, the fluid containing a dispersion of electrically polarizable nanoparticles and applying an AC voltage across a portion of the elongate structure so as to cause an alternating electric current to pass through the narrow section such that a break in the elongate structure is formed at the narrow section, the break being defined between a first broken end and a second broken end of the elongate structure, and then cause, when the break is formed, an alternating electric field to be applied to the fluid such that a plurality of the nanoparticles contained in the fluid are assembled to form a continuation of the elongate structure extending from the first broken end towards the second broken end so as to join the first and second broken ends.

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.
