    Abstract: Disclosed herein is a device for cleaning a photomask, which prevents haze from being generated on a surface of the photomask during a photolithography process. The photomask is heat treated to remove residual ions on a surface thereof and to induce curing and oxidation of Cr and MoSiON layers, thereby preventing diffusion of the ions. Etching of Cr and MoSiON layers due to a cleaning process is suppressed in order to significantly reduce a change in phase and transmissivity of optical properties of Cr and MoSiON.

    Abstract: A parts immersion system and method includes a trough through which a conveyor belt carries the parts. A chemical solution is introduced into the trough through an opening in the bottom of the trough, from above the trough, and/or from the sides of the trough. The parts on the conveyor belt in the trough have a tendency to retard liquid movement out of the open ends of the trough thereby allowing the chemical solution to accumulate in the trough resulting in a greater immersion of the parts in the chemical solution. A gate may be provided near one or both ends of the trough to further enhance the accumulation of the chemical solution in the trough. Flights may extend upwardly from the conveyor belt to further enhance liquid retention in the trough between the flights. Flexible seals at the ends of the flights may contact sidewalls of the trough. One or more vibrators may be provided to enhance drainage of the chemical solution from the parts as the parts exit the trough.

  • Patent number: 7252098
    Abstract: A method and apparatus for cleaning, rinsing and Marangoni drying substrates is provided. A line of fluid is sprayed along a substrate surface forming an air/fluid interface line, and a line of drying vapor is supplied to the interface line to achieve Marangoni drying. Thus, a large portion of the substrate is simultaneously dried. A preferred apparatus employs a tank of cleaning and/or rinsing fluid. Above the tank fluid a source of rinsing fluid directs rinsing fluid to the surface of a substrate forming a meniscus on the substrate surface as the substrate is lifted from the cleaning fluid, and a drying vapor source directs drying vapor to the meniscus. The drying vapor lowers the surface tension of the meniscus, inducing a Marangoni flow of rinsing fluid from the substrate's surface, and thereby drying the substrate. The cleaning fluid tank has a substrate receiving and cleaning portion and a substrate rinsing portion.

    Abstract: A heat sterilization process for small, washed, and bagged articles such as vial stoppers includes a conditioning or air removal phase prior to sterilization. During the air removal phase, a substantial majority of the liquid moisture is removed from the bagged articles by introducing brief periods of dry, warm air to the autoclave chamber. The air is introduced in short bursts at the point of greatest vacuum while pressure pulsing the chamber during the air removal phase. The air is heated and injected into the chamber through a supply valve which is rapidly opened and closed while the chamber is maintained within a preselected vacuum range between the pressure pulses. The result is a greatly reduced time for a complete sterilization and drying process.

The shield uses overlapping blades to cover the bath, making a physical barrier between the bath chemistry and the wafer rinse water. The blades are interconnecting ribs that actuate around a common pivot axis. A linear mechanical actuator controls the blade movement, moving the top-most blade, which in turn, moves an adjacent lower blade. Each upper blade is interconnected to an adjacent lower blade by upper and lower ledges, a pivot boss and interlocking cut, and a curved ledge on each blade's body surface. The interconnecting features allow the blades to move one another out for extension or in for retraction. The interlocking blades are inclined above one another, forming grooves to redirect the rinse water away from the chemical bath.

    Abstract: A cleaning system that utilizes an organic cleaning solvent and pressurized fluid solvent is disclosed. The system has no conventional evaporative hot air drying cycle. Instead, the system utilizes the solubility of the organic solvent in pressurized fluid solvent as well as the physical properties of pressurized fluid solvent. After an organic solvent cleaning cycle, the solvent is extracted from the textiles at high speed in a rotating drum in the same way conventional solvents are extracted from textiles in conventional evaporative hot air dry cleaning machines. Instead of proceeding to a conventional drying cycle, the extracted textiles are then immersed in pressurized fluid solvent to extract the residual organic solvent from the textiles. This is possible because the organic solvent is soluble in pressurized fluid solvent. After the textiles are immersed in pressurized fluid solvent, pressurized fluid solvent is pumped from the drum.

  • Publication number: 20040159341
    Abstract: A photoresist stripping apparatus and a corresponding method for removing photoresist layers after a patterned polyimide layer is developed. The photoresist-stripping apparatus includes a transporting unit, a stripping unit, a washing unit, a drying unit and a control unit. The transporting unit connects the stripping unit, the washing unit and the drying unit. The control unit is responsible for controlling the transport sequence and timing of the transporting unit. The method of stripping the photoresist layer off the OLED panel includes providing a stripping solution to the stripping unit to remove photoresist layers. The OLED panel is jet-cleaned with a washing solution in the washing unit so that any residual stripping agent is removed. Finally, the surface of the OLED panel is blown dry.

  • Publication number: 20040144401
    Abstract: A cleanling apparatus for removing contaminants from the surface of a substrate includes two parts: one which produces an aerosol including frozen particles and directs the aerosol onto the surface of the substrate to remove contaminants from the surface by physical force, and another part in which a fluid including a gaseous reactant is directed onto the surface of the substrate while the surface is irradiated to cause a chemical reaction between the reactant and organic contaminants on the surface, to chemically removing the organic contaminants. In the method of cleaning the substrate, the physical and chemical cleaning processes are carried out in a separate manner from one another so that the frozen particles of the aerosol are not exposed to the effects of the light used in irradiating the surface of the substrate. Therefore, the effectiveness of the aerosol in cleaning the substrate is maximized.

  • Patent number: 6748960
    Abstract: An apparatus for supercritical processing of multiple workpieces comprises a transfer module, first and second supercritical processing modules, and a robot. The transfer module includes an entrance. The first and second supercritical processing modules are coupled to the transfer module. The robot is preferably located with the transfer module. In operation, the robot transfers a first workpiece from the entrance of the transfer module to the first supercritical processing module. The robot then transfers a second workpiece from the entrance to the second supercritical processing module. After the workpieces have been processed, the robot returns the first and second workpieces to the entrance of the transfer module. Alternatively, the apparatus includes additional supercritical processing modules coupled to the transfer module.

  • Patent number: 6746543
    Abstract: A cleaning apparatus and a cleaning method for cleaning a object are provided. In the cleaning apparatus, a drying chamber 42 and a cleaning bath 41 are separated from each other up and down, respectively. Thus, a space in the drying chamber 42 can be insulated from a space of the cleaning bath 41 through rotary doors 59a and a slide door 72. In the cleaning method, a cleaning process in the cleaning bath 41 is carried out while sealing it by the rotary doors 59a. On the other hand, a drying process in the drying chamber 42 is accomplished while sealing and closing it by the slide door 72. Consequently, there is no possibility that, during the drying process, the object is subjected to a bad influence from a chemical treatment.
