Abstract: Systems and methods for treating a carbon overcoat surface are described. In one embodiment, the method may include depositing a magnetic recording layer over a substrate, depositing a carbon overcoat layer over the magnetic recording layer, and exposing a carbon overcoat layer to water in gas phase after the carbon overcoat layer is deposited on the magnetic recording layer. In some cases, the method may include depositing a lubricant over the outer surface of the carbon overcoat after exposing the carbon overcoat layer to the water in gas phase.
Abstract: A workpiece (100) having substrate, such as a glass substrate, can be etched by a laser or by other means to create recessed features (200, 202). A laser-induced forward transfer (LIFT) process or metal oxide printing process can be employed to impart a seed material (402), such as a metal, onto the glass substrate, especially into the recessed features (200, 202). The seeded recessed features can be plated, if desired, by conventional techniques, such as electroless plating, to provide conductive features (500) with predictable and better electrical properties. The workpieces (100) can be connected in a stacked such that subsequently stacked workpieces (100) can be modified in place.
Abstract: A method of controlling application of at least one material to a substrate is provided. The method includes configuring at least one array having a plurality of micro-applicators such that a subset of the micro-applicators is individually addressable to apply the at least one material to the substrate. Individually addressing the subset of micro-applicators provides control of a pattern width of a coating applied to a substrate, control of a flow rate of the material applied to the substrate, control of an angle of application of the material to the substrate, control of which and how many materials are applied to the substrate, and combinations thereof.

Abstract: A method of detecting a defect in an applied volume of material includes detecting a pressure discontinuity during dispensing the volume of material along a predetermined path on a substrate. The pressure discontinuity is indicative of the defect in the applied volume of material. The location of the defect along the predetermined path is function of a start time of the pressure discontinuity and the size of the defect is a function of a time duration of the pressure discontinuity. The method can further include determining whether or not to repair the defect as a function of the location and the size of the defect in the applied volume of material. The method includes repairing the defect by re-directing the material applicator to the location of the defect and dispensing additional material at the location of the defect.

Abstract: Reflective luminescent markings on a road or sign surface are formed by applying onto the surface a base material which is liquid in an initial state for application and sets or cures to form a solid layer after application where the base material contains a fine/medium filler material of glass ground from recycled materials in a rotary mill. Coarse material from the grinder is separated out and supplied as a separate material to be applied onto the surface of the layer of base material and fine ground glass. The base material is connected or impregnated with a luminescent material such as photo luminescent 2 4 6 trichlorophenyl in a binder such as polyurea.

Abstract: A nanoparticle continuous-coating device based on spatial atomic layer deposition. A first-stage pipeline unit, a second-stage pipeline unit, a third-stage pipeline unit and a fourth-stage pipeline unit which are connected sequentially. The first-stage pipeline unit is used for providing a first precursor and enabling the first precursor to be adsorbed on surfaces of nanoparticles. The third-stage pipeline unit is used for providing a second precursor and enabling the second precursor to react with the first precursor on the surfaces of the nanoparticles, so that a monomolecular thin film layer is generated on the surfaces of the nanoparticles. The second-stage and fourth-stage pipeline units are used for cleaning the nanoparticles and discharging the redundant first precursor, the redundant second precursor or reaction by-products.

Abstract: Methods are provided for fabricating functional nanostructures (e.g., nanowires/nanofibers) via chemical vapor deposition polymerization of paracyclophanes or substituted paracyclophanes onto and through a structured fluid, such as a film of liquid crystals, on a substrate. A one-step process is provided that does not require the use of any solid templates, nor does it require any volatile solvents, additives or catalysts. The resulting nanowires/nanofibers can be in the form of aligned nanowires/nanofibers arrays supported on any solid material, in the form of nanofibers mats supported on porous materials, or as individual free-standing nanowires/nanofibers. By using chiral liquid crystals, chiral nanofibers can be fabricated. The functional nanowires/nanofibers can contain one or more type of surface reactive groups that allows for post surface chemical modifications on the nanowires/nanofibers. Such nanostructures can be used in a range of different applications, including in biomedical applications.

Abstract: Implementations of the present disclosure provide methods for treating a processing chamber. In one implementation, the method includes purging a 300 mm substrate processing chamber, without the presence of a substrate, by flowing a purging gas into the substrate processing chamber at a flow rate of about 0.14 sccm/mm2 to about 0.33 sccm/mm2 and a chamber pressure of about 1 Torr to about 30 Torr, with a throttle valve of a vacuum pump system of the substrate processing chamber in a fully opened position, wherein the purging gas is chemically reactive with deposition residue on exposed surfaces of the substrate processing chamber.
Abstract: A method of applying a coating liquid to an optical fiber is described. An optical fiber is drawn through a guide die into a pressurized coating chamber and through the pressurized coating chamber to a sizing die. The pressurized coating chamber contains a coating liquid. The method includes directing coating liquid in a direction transverse to the processing pathway of the optical fiber in the pressurized coating chamber. The transverse flow of coating liquid counteracts detrimental effects associated with gyres that form in the pressurized coating chamber during the draw process. Benefits of the transverse flow include removal of bubbles, reduction in the temperature of the gyre, improved wetting, homogenization of the properties of the coating liquid in the pressurized coating chamber, and stabilization of the meniscus.
