Abstract: Apparatuses and processes for maskless deposition of electronic and biological materials. The process is capable of direct deposition of features with linewidths varying from the micron range up to a fraction of a millimeter, and may be used to deposit features on substrates with damage thresholds near 100° C. Deposition and subsequent processing may be carried out under ambient conditions, eliminating the need for a vacuum atmosphere. The process may also be performed in an inert gas environment. Deposition of and subsequent laser post processing produces linewidths as low as 1 micron, with sub-micron edge definition. The apparatus nozzle has a large working distance—the orifice to substrate distance may be several millimeters—and direct write onto non-planar surfaces is possible.

Abstract: A pneumatic nozzle for roller coating is revealed. A workpiece to be coated is fixed on a rotating power source of a machine. A high-pressure pneumatic nozzle and a material supply nozzle, both corresponding to the workpiece, are arranged at the machine. The workpiece is driven to rotate by the rotating power source while the material supply nozzle applies coating material to the workpiece and the high-pressure pneumatic nozzle releases high pressure gas. The coating material attached on the surface of the workpiece is pushed by the high pressure gas and spread uniformly on the workpiece by rotating workpiece. Thereby the material is coated smoothly in a non-contact way and the thickness of the coating material is controlled in micron scale. This helps following manufacturing of three-dimensional microstructures on rolls for producing roll dies and increases the practical value.

Abstract: A method of creating an air barrier on both sides of an innerliner splice on the inside surface of a green tire when a bladder release lubricant is being applied thereto to prevent contamination of the splice. High pressure air is directed through air nozzles on both sides of the innerliner splice just prior to and during the application of the lubricant. A pressure sensor detects high or low air pressure during the creation of the air barriers to stop the spray of lubricant should either situation be detected.

Abstract: An improved Wurster coater in which conditioned fluidizing gas, drawn through a coating chamber bowl from a plenum by a vacuum fan, is directed through a perforated gas distribution plate through one or more Wurster tubes. The perforated gas distribution plate defines three concentric gas flow zones: a central high-flow up-bed zone beneath the Wurster tube, a surrounding annular lower-flow down-bed zone, and an outer peripheral bypass zone defining a bypass cavity underlying the outer lower wall of the bowl. A controlled bypass flow of conditioned fluidizing gas is directed into the bypass zone, either around the edge of the distribution plate or through relatively larger holes in its plate's outer periphery, which causes that portion of the fluidizing gas to flow radially inward across the distribution plate, thereby sweeping particles away which would otherwise stagnate at the inner corners of the bowl due to low gas velocity in that region.

The functional device is formed by allowing a volatile ingredient of the droplet, while allowing a solid component of the droplet to remain on the substrate.

Abstract: In the present invention, a gas flow restraining ring facing corner portions of the front face of a substrate horizontally held on a substrate holding unit and movable up and down, is set to a predetermined height in accordance with a coating treatment. Then, a coating solution containing a coating film forming component and a solvent is applied to the front face of the substrate and spread into a thin film state by a so-called spin coating method, and thereafter the substrate is rotated at a high speed so that the coating solution is dried. In this case, it is possible to control fresh gas flow from above the substrate to decrease the difference in evaporation rate of the solvent between the coating solution on the corner portions of the substrate and the coating solution inside them, thus enabling the coating treatment uniform within a plane on the substrate.

Abstract: Of a substrate-facing surface 24 of an atmosphere blocking member 2, a central area 241 which is faced with an approximately central portion of a substrate S is a flat surface while a periphery edge area 242 which is faced with a periphery edge of the substrate S is an angled surface which becomes closer to the substrate S with a distance toward a periphery edge of the substrate-facing surface 24. Hence, a micro-space SP between the substrate S and the atmosphere blocking member 2 becomes gradually narrower in a direction R which is toward the periphery edge of the substrate S. As an atmosphere gas is fed into the micro-space SP, the atmosphere gas is compressed in the vicinity of a periphery edge of the micro-space SP and a pressure rises. As a result, the micro-space SP becomes positively pressurized as compared with a mist-splashed atmosphere, which effectively prevents a mist from invading other major surface S2 of the substrate S.

The upper lip adjusts a gap of a gas outlet cooperatively with the lower lip, and can be easily installed in a lip support unit while adjusting the gap of the gas outlet stably. Also, edge over coating (EOC) of the steel strip can be prevented without an additional auxiliary nozzle.

The air supplied to the space is supplied to the processing chamber through each of the slits in the processing chamber. This causes a twister-shaped air current to be generated within the processing chamber.

Abstract: An improved Wurster coater in which conditioned fluidizing gas, drawn through a coating chamber bowl from a plenum by a vacuum fan, is directed through a perforated gas distribution plate through one or more Wurster tubes. The perforated gas distribution plate defines three concentric gas flow zones: a central high-flow up-bed zone beneath the Wurster tube, a surrounding annular lower-flow down-bed zone, and an outer peripheral bypass zone defining a bypass cavity underlying the outer lower wall of the bowl. A controlled bypass flow of conditioned fluidizing gas is directed into the bypass zone, either around the edge of the distribution plate or through relatively larger holes in its plate's outer periphery, which causes that portion of the fluidizing gas to flow radially inward across the distribution plate, thereby sweeping particles away which would otherwise stagnate at the inner corners of the bowl due to low gas velocity in that region.

Abstract: A process tool, preferably a spin coater, includes a set of at least three arms and an adjustable rinse nozzle. The arms lift a substrate, e.g. a semiconductor wafer, from a chuck inside the process chamber after having performed the corresponding manufacturing step, e.g. coating. The contact area between the arms and the substrate is as small as possible. The rinse nozzle dispenses a solvent liquid onto the backside of the substrate, thereby removing contaminating particles located at the area of contact between the vacuum channels of the chuck and the substrate. The set of arms rotates for a homogeneous cleaning. A gas flowing out of vacuum ports of the chuck prevents the vacuum ports from being obstructed with particles. While the substrate is being lifted, the chuck can also be cleaned by dispensing the solvent liquid onto the chuck.

Abstract: A method of forming a film of a coating solution on a substrate includes steps of moving a coating solution discharge member relative to a substrate while a coating solution is being discharged from the coating solution discharge member to the surface of the substrate, and changing a discharge direction of the coating solution to an outer peripheral portion of the substrate to make the amount of application to the outer peripheral portion smaller than that to other portions. This can reduce the amount of application to the outer peripheral portion of the substrate, thereby making it possible to restrain protuberance of the coating solution at the outer peripheral portion of the substrate caused by surface tension. Consequently, a coating film which is uniform also at the outer peripheral portion on the substrate is formed.
