  • Patent number: 6843259
    Abstract: The present invention relates to a solution treatment unit for supplying a treatment solution to a substrate to treat the substrate within a treatment container, and an inner container surrounding an outer periphery of the horizontally held substrate with its upper and lower faces open is provided in the treatment container. An exhaust pipe for exhausting an atmosphere in the treatment container is provided in a bottom portion of the treatment container and inside the inner container. An exhaust port of the exhaust pipe is open at a position higher than the bottom portion. A drain port for draining the treatment solution in the treatment container is provided in the bottom portion. According to the present invention, the drain of a solution and the exhaust of an atmosphere can be performed separately without being mixed, and hence pressure loss of a fan on the factory side which performs an exhaust operation can be reduced, resulting in a reduction in excess power consumption.

  • Publication number: 20040020520
    Abstract: An apparatus for cleaning a wafer includes a plurality of holders for contacting and securing peripheral portions of a wafer, and for rotating the wafer, a first plate disposed to face a first surface of the wafer, the first plate having a plurality of first nozzles for spraying a first cleaning solution onto the first surface of the wafer, and a second plate disposed to face a second surface of the wafer that is opposite to the first surface, the second plate having a plurality of second nozzles for spraying a second cleaning solution onto the second surface of the wafer. In operation, the first and second plates and the wafer are rotated in opposite directions. The opposite rotation causes the cleaning solutions to flow abruptly thereby increasing a frictional force between the surfaces on the wafer and the cleaning solutions to improve the efficiency of the cleaning process.

    Abstract: An apparatus for cleaning a substrate includes a bearing assembly, a tubular shaft, a substrate support, a process bowl, and a dispenser. The tubular shaft has an upper end and a lower end. The lower end is rotatably mounted to the bearing assembly. The shaft provides an area through which cleaning liquid can be directed. The substrate support has a lower region connected to the tubular shaft and an upper region that supports the substrate. The process bowl surrounds and is spaced outwardly from the substrate support. The process bowl has a slot in an outer wall that receives a robot arm that positions the substrate on the substrate support and that withdraws the substrate from the substrate support. The dispenser has an outlet that directs liquid through the area, toward the upper region. The dispenser is positioned beneath the upper region.

  • Publication number: 20040007257
    Abstract: An apparatus for treating a wafer preferably includes a rotating chuck for rotating the wafer and a treating fluid supplying part for supplying the wafer with one or more treating fluids. The treating fluid(s) can be used to clean and/or dry the wafer. The treating fluid supplying part preferably includes a receiving portion for receiving a treating fluid, and a slit communicating with the receiving portion for applying the treating fluid to a surface of the wafer. An ultrasonic oscillating part can be installed in the receiving portion and can apply ultrasonic oscillation to the treating fluid. The treating fluid for applying the ultrasonic oscillation is preferably provided uniformly across the treated surface of the wafer. The effectiveness of the cleaning process can thereby be improved, and damage to patterns formed on the wafer can be reduced.

    Abstract: An apparatus for cleaning semiconductor wafers includes a chamber, a bubbler having a vapor generating part for generating alcohol vapor and a spray pipe for spraying the alcohol vapor into the chamber, a gas supply nozzle for spraying gas into the chamber to dry the wafers, a liquid supply nozzle for supplying cleaning liquid into the chamber and a discharge system. The spray pipe of the bubbler has a liquid retention portion that keeps condensate of the alcohol vapor from issuing into the chamber. The gas supply nozzle has a spray outlet configured to spray the same amount of the drying gas onto all of the wafers in the chamber. The liquid supply nozzle has liquid supply openings only in a side portion thereof so that liquid alcohol will not become trapped therein.

    Abstract: A to-be-cleaned substrate is cleaned by use of an acid liquid agent in a cleaning cup, the remaining acid liquid agent is washed out by use of pure water, then an alkaline liquid agent is emitted to the surface of the to-be-cleaned substrate in the same cleaning cup to remove the acid liquid agent remaining on the to-be-cleaned substrate. A neutralization reaction between the acid and alkali is caused by emitting the alkaline liquid agent to the surface of the to-be-cleaned substrate so as to efficiently remove the acid liquid agent remaining on the surface of the to-be-cleaned substrate.

    Abstract: Purge bars for blowing excess residual cleaning fluid from an object, particularly a semiconductor wafer, before or as the wafer is removed from a cleaning chamber of a CMP cleaner, for example. Typically, a purge bar is mounted on each side of the cleaning chamber for blowing nitrogen or clean, dry air (CDA) against a corresponding surface of the wafer to remove the excess cleaning fluid from the wafer. The purge bars may be connected to a controller for a wafer transfer device which removes the wafer from the cleaning chamber, such that the purge bars are actuated as the wafer transfer device begins to remove the wafer from the chamber.

  • Patent number: 6659114
    Abstract: An automated kitchenware washing tank has a pump system with a pump and fluid conduits to couple the pump between an intake opening through one of the walls and discharge openings in the wall of the tank. At least some of the discharge openings are preferably formed in at least one angled portion of the tank wall that faces downwardly into the tank, and, more preferably, on two opposed angled portions that face downwardly into the tank. A control system may be coupled to the pump for controlling the speed with which the pump supplies cleaning fluid to the discharge openings. The control system comprises a speed selector that is adapted to allow a user to activate the speed selector to select between at least two different speeds for pumping the cleaning fluid to the discharge openings. In operation, the automated washing tank pumps cleaning fluid from within the tank through the intake outlet through the fluid conduits and out of the discharge openings into the tank to create turbulence within the tank.
