NOVELTY - The apparatus comprises a capillary tube with an ingress opening to receive a liquid and an egress opening to release the liquid, a solid conductor positioned in a conduit of the tube, where the conductor and the conduit have dimensions to cause a surface tension of the liquid to prevent a constant flow of the liquid from the egress opening, and a power supply coupled to the conductor to apply a charge to the liquid to overcome the surface tension and form a single jet stream of the liquid applicable on a substrate to create a pattern.    USE - The apparatus is useful for applying materials on substrates for manufacturing electronic devices such as a computer, a display, a solar cell, an integrated circuit, a printed circuit board, a wafer and their portions (all claimed).    ADVANTAGE - The apparatus is capable of effectively, accurately and repeatedly applying desired patterns on substrates in a simple manner thus reducing the manufacturing time and cost of the electronic devices and improving the quality and productivity of the electronic devices.    DETAILED DESCRIPTION - The apparatus comprises a capillary tube with an ingress opening to receive a liquid and an egress opening to release the liquid, a solid conductor positioned in a conduit of the tube, where the conductor and the conduit have dimensions to cause a surface tension of the liquid to prevent a constant flow of the liquid from the egress opening, and a power supply coupled to the conductor to apply a charge to the liquid to overcome the surface tension and form a single jet stream of the liquid applicable on a substrate to create a pattern. The single jet stream is controllable in part by a viscosity of the liquid. A first portion of a structure of the single jet stream corresponds to an approximation of a Taylor cone extending from the egress opening of the conduit. A second portion of the structure of the single jet stream corresponds to: a single stream extending from the Taylor cone and transitioning to droplets before a point of contact of the substrate, where the single stream has a smaller diameter than the conduit of the tube; the single stream extending from the Taylor cone and transitioning to a spray before the point of contact of the substrate; the single stream extending from the Taylor cone and contacting the substrate without noticeably altering the Taylor cone; or the single stream extending from the Taylor cone, contacting the substrate and noticeably altering the Taylor cone. The second structure of the single jet stream is controlled by influencing a flow characteristic of the single stream, a conductivity of the liquid, the viscosity of the liquid, a dielectric constant of the liquid, a surface tension of the liquid, a distance between the substrate and the egress opening of the tube, a voltage applied to the liquid, or a motion between the substrate and the single stream. The diameter of the single stream with the noticeable alteration in the Taylor cone is controlled by influencing the flow characteristic of the single stream or a motion between the substrate and the second structure of the single jet stream. The liquid comprises a precursor solution, which comprises a metal, a metal compound, a sol-gel processed material, a polymer, an oligomer, an oxide, a ceramic, an organic material, a biomaterial and/or a biological material. The solid conductor has an axial length with first and second ends, where the first end points in a direction of the ingress opening and the second end points in a direction of the egress opening. The second end generates an electric field that applies the charge to the liquid responsive to a voltage applicable by the power supply. The electric field is influenced by the applied voltage and a diameter of the second end. The voltage applied to the solid conductor is constant, and the electric field generated by the second end is greater when the diameter of the second end point is smaller. The solid conductor corresponds to a conductive needle having a sharp point corresponding to the second end. The sharp point has a diameter smaller than a diameter of the conduit of the tube. The position of the solid conductor in the conduit of the tube does not extend or extends the second end of the solid conductor beyond the egress opening of the tube. The constant flow of the liquid is prevented by the surface tension of the liquid and its viscosity while the conductor is electrically neutral. The conductor is a sleeve positioned in the tube, where a diameter of the sleeve results in one of the outer surface of the sleeve contacting the surface of the conduit or outer surface of the sleeve having a separation from the surface of the conduit of the tube. The tube comprises an insulator. The apparatus further comprises: a reservoir or a device that feeds the liquid into the tube; an imaging system to determine a quality of the single jet stream and an application of the single jet stream on the substrate; a temperature application device coupled to a portion of the apparatus to control a temperature of the substrate or the single jet stream; a thermal sensor device to sense the temperature of the substrate or the single jet stream; a device to propel the liquid into the ingress opening of the tube; a position altering apparatus coupled to the substrate and the tube to shift the substrate and tube in a plane to create a pattern on the substrate with the single jet stream; a housing assembly to hermetically seal a portion of the apparatus; a device to cause an injection of a gas or a fluid in the housing assembly and to cause approximate vacuum in the housing assembly; a controller to manage operation of portions of the apparatus to apply the pattern on the substrate; a removable obstruction to obstruct an application of the liquid to the substrate; additional tubes with a corresponding conductor positioned in each additional tube; and an electric, magnetic or electromagnetic device to manipulate the charged single jet stream. INDEPENDENT CLAIMS are included for:    (1) a method for applying materials on substrates;    (2) an electronic device; and    (3) a computer-readable storage medium.
