  • Publication number: 20090214326
    Abstract: A tray handling apparatus comprises a plurality of guides, a chuck device, a linear movement device, and a rack and pinion device. A space defined by the erected guides is used to hold a tray stack. The chuck of the chuck device is located at the center position of the bottom area of the space. The linear movement device is used to move the chuck relative to the guides. The rack and pinion device is used to cause the guides to move symmetrically. When an operator moves any one of the guides, the other guides move symmetrically and the center of the bottom area of the space surrounded by the guides remains at the same location during the movement of the guides. The operator does not need to adjust the position of the chuck if the positions of the guides are changed.

A computer controls a mechanism having a pair of wafer-supporting blades to insert the wafers into the chamber. The computer determines from position sensors when the first wafer is centered over the first platform, then actuates lift pins associated with the first platform to lift the first wafer off of its respective blade. Then the computer in the same way in response to other position sensors moves the second wafer into alignment with the second platform, and raises by lift pins the second wafer off of its respective blade. Thereafter the computer removes the blades from the chamber, and lowers the wafers in precise positions onto their respective platforms.

    Abstract: A wafer sorting system is provided. The wafer sorter system is used to simultaneously sort multiple semiconductor wafers of a cassette. The wafer sorter system includes multiple arms which extend from a tower. These arms are at different vertical locations along the tower. The wafer sorter system also comprises a robotic arm which may move the tower to a position where the arms contact wafers. These wafers are in different vertical slots of a cassette. Further included in the wafer sorter system is a belt which may rotate to move arms vertically through slots of the tower. Wafers may become attached to arms by applying a vacuum suction to each arm. The arms having wafers may be rotated to the belt in a clockwise or counterclockwise direction about a portion of the tower via a slot in the tower. The arms may then be attached to the belt. After the belt moves the arms to new levels of the tower, the arms may then be rotated back to their original positions.

  • Patent number: 6210093
    Abstract: An apparatus for displacing a plurality of objects from a pickup station to a deposition station offset horizontally from the pickup station has a support movable in a horizontal transport direction between a position directly above the pickup station and a position directly above the deposition station, an elongated lift plate underneath the support and provided with grabs for picking up and releasing the objects, a flexible belt having a lower end extending in the direction and secured to the lift plate, a drive on the support for paying out and winding in the belt and thereby raising and lowering the plate, and rigid links connected between the plate and the support for inhibiting movement of the plate perpendicular to the direction.

  • Patent number: 6176667
    Abstract: A multideck wafer processing system is described for the treatment of semiconductor wafers. The system includes at least two process chambers stacked one above the other to provide for higher wafer throughput per unit area of cleanroom space. The stacked process chambers enable sharing of pressurization, gas, electrical, and control support services for the processing chambers.

  • Patent number: 6176669
    Abstract: This invention relates to a device for removing and transporting articles, such as ophthalmic lens mold sections, or packaging elements from a mold. The invention, in one embodiment includes first, second, and third assemblies; the first of which removes the articles from the molding station at a first location and transports them to a second location; the second assembly receives the articles from the first assembly and transports them to a third location, and the third assembly receives the articles from the second assembly and transports them to a fourth location. A second embodiment includes a flipper assembly disposed between the first and second assemblies, which flipper receives the articles from the first assembly and inverts them before depositing them onto the second assembly. This second embodiment is useful in conjunction with molded articles which are transported to the flipper assembly in an inverted position.
