Abstract:
Film coating unit has a substrate holder for holding a wafer, a coating solution discharge nozzle, and anti-drying boards opposed to a surface of the wafer. The coating solution is applied to the surface of the wafer in a direction from a front end toward a rear end of the wafer while relatively moving the substrate holder with respect to the coating solution discharge nozzle. During that time, the anti-drying boards are disposed at height of maximum 2 mm from the surface of the wafer so as to form dense atmosphere of a solvent between the surface of the wafer and the anti-drying board. Thereby the coating solution on or over the surface of the wafer is restrained from being dried and a coating film is formed with even thickness on or over the surface of the wafer.
Abstract:
A system for controlled dispensing of a material onto an elongated window component. A nozzle dispenses the material into contact with a surface of the elongated window component at a delivery site located along a path of travel of the elongated window component. A conveyer moves the elongated window component along the path of travel relative to the nozzle at a controlled speed. A metering pump delivers controlled amounts of the material to the nozzle. A pressurized bulk supply delivers the material to an inlet to the metering pump. A controller regulates the speed of the metering pump to control the flow rate of the material dispensed by the nozzle.
Abstract:
A coating apparatus coats a liquid material on a substrate in a coating chamber. A first liquid supply system that supplies the liquid material is provided in the coating chamber. A second liquid supply system is provided in the first liquid supply system that supplies a liquid that cleans or that deactivates the liquid material remaining in the coating chamber and/or in the first liquid supply system. A coating apparatus, a thin film forming method, a thin film forming apparatus, a semiconductor device manufacturing method, an electro-optic device, and an electronic instrument are provided that enable a high performance thin film with few defects and with a high degree of reproducibility to be obtained, that allow maintenance of the apparatus to be performed efficiently and safely, and that enable a thin film to be formed at low cost.
Abstract:
The present invention provides an apparatus and method that uses positive displacement of coating material using a computer controlled, motorized dispensing device. The flow rate of the dispensing device is controlled, and the positive displacement apparatus and method result in a precise amount of coating that is dispensed. The positive displacement coating apparatus and method allow for much more accurate and consistent coating from part to part. Because the positive displacement coating apparatus precisely controls the flow rate of the coating, differences in viscosity of the coating do not adversely affect the amount of the coating that is dispensed. In addition, the fluid flow path or pressure differential do not adversely affect the amount of the coating that is dispensed.
Abstract:
A system and method for dispensing liquid coating patterns of varying width. The system uses a film coater, a liquid supply coupled in fluid communication with the film coater and configured to supply liquid to the film coater under pressure, and a liquid pressure regulator operatively connected to the coater. The liquid pressure regulator selectively adjusts the pressure of the liquid supplied to the film coater and is operated by pressurized air. A selector valve is coupled to the liquid pressure regulator. First and second air pressure regulators are coupled to the selector valve and can selectively deliver air at first and second pressures to the selector valve. The selector valve is moved between first and second positions for selectively delivering air under either the first pressure or the second pressure to the liquid pressure regulator to thereby cause the liquid to be delivered to the film coater at different pressures to change the width of the dispensed pattern.
Abstract:
A coating apparatus includes support for supporting a mother substrate including unit substrates, a coater for coating the unit substrate with photosensitive materials, a detector for detecting foreign matters, a remover for removing the foreign matters from the unit substrate, and a controller for controlling the coater, detector, and remover. The coater includes a body containing the photosensitive materials, and inlet and outlet portions for inputting and outputting the photosensitive materials to/from the body. A width of the outlet portion is the same as that of the unit substrate. The detector is positioned at front of the coater to detect the foreign matters before the coating process. The remover removes the foreign matters. The coater discharges the photosensitive material only onto the unit substrate. Discharging of the photosensitive material is interrupted when the foreign matters are found. The coating apparatus requires less photosensitive material, and can be more efficient
Abstract:
Upon a substrate subsequent layers of elastic ink are jetted using an ink jet printing system. Each layer is immobilised by a immobilisation step before jetting the following layer. A printing relief is gradually formed to obtain a flexographic printing plate allowing accurate control over the relief and slopes of the printing plates. Use can be made of different inks or immobilisation step to obtain different layer characteristics. Inks can be immobilised using UV curing. The recorded relief of the layers can be measured and corrections can be applied using a feed-back loop. A rejuvenation process for printing plates can be constructed using the described method. An elastic base layer can be provided on the substrate to provide better plate characteristics.

An apparatus for aligning a dispenser includes: a table that can move horizontally in forward/backward and left/right directions for receiving a substrate of at least one liquid crystal display panel; first and second dummy aligning plates on the table with a certain space therebetween; a syringe for supplying a sealant onto the first and second dummy aligning plates to form first and second alignment patterns; a first image camera for detecting an image of the first alignment pattern; a second image camera for detecting an image of the second alignment pattern; and an alignment controller for aligning the image of the first image camera with a first reference position and the image of the second image camera with a second reference position.
Abstract:
Systems and methods for applying or dispensing surgical prep solution are disclosed. The applicator system includes a spreader element and a container of surgical prep solution. The spreader element includes a body with an orifice covered by a pad. The orifice is in fluid communication with a passage through an elongated stem connected to the body. The container may be collapsible with only limited recovery. The spreader element may include a receptacle for receiving the container.
Abstract:
A method of plating bath composition control. The method may include analysis of a plating bath to determine byproduct concentrations and changing the composition of the plating bath as a result thereof. Additionally, plating bath solution may be circulated between reservoirs before, during, or after the analysis and the changing of the composition. Methods may be carried out with use of a system having separate reservoirs, an analyzer, and a dosing controller for the changing of the composition.
