| 20080210258 | SCRUBBER BOX AND METHODS FOR USING THE SAME - A scrubber box is provided that includes a tank adapted to receive a substrate for cleaning, supports outside of the tank and adapted to couple to ends of scrubber brushes disposed within the tank, a motor mounted to each of the supports and adapted to rotate the scrubber brushes, a base to which the supports are pivotally mounted via spherical bearings adapted to permit toe-in of the scrubber brushes, a brush gap actuator adapted, via a crank and rocker mechanism, to substantially simultaneously pivot the supports toward or away from each other so as to permit the scrubber brushes to substantially simultaneously achieve or break contact with the substrate, and a toe-in actuator adapted to move two of the spherical bearings toward or away from each other so as to adjust a toe-in angle between the scrubber brushes. | 09-04-2008 |
| 20080291448 | METHODS AND APPARATUS FOR FINDING A SUBSTRATE NOTCH CENTER - Methods and apparatus are provided for locating a notch and/or a center of the notch of a substrate. An exemplary method includes rotating a substrate; illuminating an edge of the substrate with a light beam as the substrate rotates; detecting a change in light intensity of the light beam as the substrate rotates; determining a rough location of a notch in the edge of the substrate based on a position of the substrate when the change in light intensity of the light beam is detected; and reversing a rotational direction of the substrate to determine a fine location of the notch in the edge of the substrate. Numerous other aspects are provided. | 11-27-2008 |
| 20090025757 | LID FOR A SEMICONDUCTOR DEVICE PROCESSING APPARATUS AND METHODS FOR USING THE SAME - A method of reducing sticking of a door of a semiconductor device processing apparatus is provided. The method comprises providing rinsing fluid to a lid of a semiconductor devise processing chamber so as to rinse particulates therefrom; and sliding a door that is operatively coupled to the lid so as to move between a closed position wherein the door occludes an opening formed in the lid, and an open position wherein the door does not occlude the opening. Numerous other aspects are provided. | 01-29-2009 |
| 20090032071 | LID FOR A SEMICONDUCTOR DEVICE PROCESSING APPARATUS AND METHODS FOR USING THE SAME - A lid for a semiconductor device processing apparatus is provided. The lid comprises a cover having an opening and a wall formed around the opening, the wall adapted to prevent fluid present on the lid from entering a body of the processing apparatus through the opening, and one or more cover edges including one or more edge walls; an outer door adapted to prevent fluid from entering the body of the processing apparatus through the opening of the cover, wherein the outer door interfaces with the wall formed around the opening and the one or more edge walls; and an inner door coupled to the outer door and adapted to prevent fluid from exiting the body of the processing apparatus through the opening of the cover. Numerous other aspects are provided. | 02-05-2009 |
| 20090217953 | DRIVE ROLLER FOR A CLEANING SYSTEM - A drive roller for use in a semiconductor substrate cleaning system is provided. In one embodiment, a drive roller includes an outer ring having a disk-shaped body, wherein the disk-shaped body has an inner cylindrical, an upper wall, and an outer cylindrical wall defining a cavity within the disk-shaped body. An inner ring is disposed within the cavity. A groove is formed along an outer side of the inner ring. The groove faces an inner surface of the outer cylindrical wall of the outer ring. | 09-03-2009 |
| 20090320875 | DUAL CHAMBER MEGASONIC CLEANER - Embodiments described herein relate to semiconductor device manufacturing, and more particularly to a vertically oriented dual megasonic module for simultaneously cleaning multiple substrates. In one embodiment, an apparatus for cleaning multiple substrates is provided. The apparatus comprises an outer tank for collecting overflow processing fluid comprising at least one sidewall and a bottom. A first inner module adapted to contain a processing fluid is positioned partially within the outer tank. The first inner module comprises one or more roller assemblies to hold a substrate in a substantially vertical orientation. A second inner module adapted to contain a processing fluid is positioned partially within the outer tank. The second inner module comprises one or more roller assemblies adapted to hold a substrate in a substantially vertical orientation. Each inner module contains a transducer adapted to direct vibrational energy through the processing fluid toward the substrates. | 12-31-2009 |
| 20110067727 | BRUSH ALIGNMENT CONTROL MECHANISM - A method and apparatus for providing uniform pressure, friction and/or contact between a substrate and a cylindrical roller in a brush-type cleaning system is described. The apparatus includes an alignment member adapted to allow pivotal movement of the cylindrical roller based on the topography of a substrate and/or the outer surface of the cylindrical roller. The method includes positioning a substrate between two cylindrical rollers, moving each of the two cylindrical rollers to a position where at least a portion of an outer surface of each of the cylindrical rollers are in contact with the major surfaces of the substrate, and rotating one or both of the substrate and the two cylindrical rollers relative to each other while allowing a longitudinal axis of one or both of the two cylindrical rollers to pivot relative to a plane defined by one of the major surfaces of the substrate. | 03-24-2011 |
