A method for rinsing a semiconductor wafer in a module utilizing a fluid delivery ring is provided. The method includes providing a process bowl having a generally circular shape bottom wall, a sidewall that extends upwardly from the bottom wall to define a cylindrical chamber, and a plurality of channels in the sidewall that extend from the bottom wall to an upper edge of the sidewall. A fluid delivery ring is attached onto the sidewall of the process bowl. Utilizing the process bowl, a plurality of supply tubes is inserted into the fluid delivery ring. The fluid delivery ring has a plurality of ring inlet and outlet pairs and a plurality of respective slots. Fluid is supplied to the supply tubes, and fluid is directed onto a surface of the semiconductor wafer defined within the process bowl.

A method for spinning a wafer to enable rinsing and drying is provided. The method includes engaging the wafer at a wafer processing plane and spinning the wafer. The method further includes moving a wafer backside plate from a first position to a second position as spinning of the wafer proceeds to an optimum spinning speed. The second position defines a reduced gap between an under surface of the wafer and a top surface of the wafer backside plate. The method also includes repositioning the wafer backside plate from the second position to the first position as the spinning reduces in speed. The first position defines an enlarged gap to enable loading and unloading of the wafer from the engaged position.

An apparatus for preparing a wafer is provided. The apparatus includes a wafer backside plate and a central shaft. The wafer backside plate has a top surface that includes a cylindrical edge lip, which defines a central aperture. The central shaft is designed to fit within the central aperture. The wafer backside plate is designed to automatically slide between an up position during rotational wager processing and a down position when the wafer is not in rotational wafer processing. A gap defined between the top surface of the wafer backside plate and the wafer is less when the wafer backside plate is in the up position than when the wafer backside plate is in the down position.

A chuck assembly for use in a substrate spin, rinse, and dry (SRD) module is provided. The chuck assembly includes a wedge, a chuck body, and a plurality of grippers. The wedge has a sidewall and is designed to move from a lower position to an upper position and from the upper position to the lower position thus opening and closing the chuck assembly, respectively. The chuck body has a cylindrical shape and is designed to include a plurality of linkage arms. The chuck body is designed to enclose the wedge such that each linkage arm is substantially in contact with the sidewall of the wedge. The cylindrical shape of the chuck body is designed to reduce air disturbance around a surface of a substrate. The plurality of grippers are designed to be coupled to the chuck body via a plurality of rotation pins. Each of the grippers is configured to stand substantially upright so as to engage the substrate when the wedge is in a lower position, and each of the grippers is configured to lie substantially flat so as to disengage the substrate when the wedge is in the lower position.
摘要:
The present invention provides methods and systems of conducting wagers, such as pari-mutuel wagers. In one exemplary embodiment, an event, such as a horse race, dog race, a combination of races, etc., is identified for which a plurality of bettors may each place at least one wager. Each bettor of the plurality is enabled to provide input regarding at least one portion of their respective at least one wager prior to the event. At least one other portion of each bettor's at least one wager is randomized prior to the event. The wager then comprises the combination of the bettor selected portion and randomized portion. In one exemplary embodiment, the player selected portion may include selecting bettor-preferred participants of the event while the randomly selected portion may include the randomly assigning a finishing order to the player selected participants.

Methods and systems of pari-mutuel wagering are disclosed to facilitate the wager construction process. In one method, patrons select runners, and betting options of selected runners are presented. In another method, a first wager is placed and other wagers are presented, wherein the additional wagers may include a runner of the first wager. Another method allows patrons to wager on a runner, wherein an area representing the runner is marked to indicate that this runner was selected on a previous wager or in the current wager. In another method, a portion of a wager is patron selected and a portion of the wager is suggested by the betting interface. In another method, patrons may construct wager(s) for single or future races, or specify criteria for those wagers. In another method, runners are displayed in a table and patrons may select or deselect runner combinations by selecting cells within the table. Methods and systems of pari-mutuel wagering that enable an organization to set rules to display the gaming activity, and an embodiment where players make subscription as well as programmed bets are described.

A load transport device that mounts to a vehicle mounted trailer hitch. The load transport system comprises a channel portion fitted with a pinion gear, and the channel portion is rigidly attached to a mounting bar that slideably engages a receiver portion of a vehicle's trailer hitch. The device also comprises an invertible shaft with an optionally-motorized rack gear system. The invertible shaft has a channel portion insertion end and a load lifting end. The invertible shaft slideably engages in either a load-low or load-high orientation depending on which end, the insertion end or the load lifting end first engages with the channel portion. The pinion gear and the rack gear system are functionally engaged. The load transport device further comprises a load support member attached to the load lifting end and comprising one or more bars that support a load.
