    摘要: A wafer processing system includes a plurality of evacuable housings connected in series to form a processing line, with a plurality isolation valves to separately isolate the housings. A track extends through the connected housings. At least one wafer carrier is moveable on the track, through the housings and along the processing line. The wafer carrier holds wafers in vertical orientation and also includes a plurality of magnets aligned along its bottom. Outside the housings, a plurality of magnetic drive units are aligned parallel with the track, with one drive unit per housing. Each drive unit includes a motor driven conveyor with a plurality of magnets mounted thereon which imposes magnetic fields inside the housing to magnetically couple with the magnets mounted on the carrier. When the motor driven conveyor moves the imposed magnetic fields, the magnetic coupling causes the wafer carrier to move. A controller operatively connected to the isolation valves and the drive units coordinates movement of wafer carriers along the processing line according to a predetermined sequence while maintaining vacuum conditions in the housings.

    摘要: Wafers from plural non-vacuum multiple wafer carriers are loaded and unloaded in an atmospheric front end of a wafer processing machine and transferred to and from the high vacuum chamber of a transfer module of a wafer manufacturing cluster tool through a plurality of single wafer loadlocks. Preferably, with the wafers oriented horizontally throughout, wafers are moved inbound to the high vacuum atmosphere through one loadlock and moved outbound through another loadlock, the outbound loadlock also actively cooling the wafer. In both the atmospheric and vacuum environments, transfer arms load and unload the loadlocks as often as possible when the other loadlock or loadlocks are sealed, and transfer wafers within the environments when all loadlocks are sealed. Preferably, the wafers are actively cooled in the outbound loadlock. Preferably also, wafers are passed through a wafer aligner after being removed from a carrier and before placed in a loadlock. When wafers from one of the carriers are being moved to and from loadlocks, another of the carriers of processed wafers is being exchanged with a carrier of unprocessed wafers.

    摘要: A device for rotating a substrate in a complex motion within a chamber which during a sputtering process. The device includes a first support element positioned within the chamber. The first support element includes a first rotating structure which is affixed between a platform for supporting the substrate and a first magnet positioned adjacent to the inner wall surface. Further, the first rotating structure is adapted to rotate about a first axis. The device further includes a second support element positioned outside of the chamber. The second support element includes a second rotating structure affixed between a planet gear adapted for engagement with a sun gear outside of the chamber and a second magnet positioned adjacent the outer wall surface and spaced apart from the first magnet. This causes the formation of a magnetic bond between the first and second magnets. Further, the second rotating structure is adapted to rotate about the first axis thereby enabling the first and second rotating structures to rotate in unison about the first axis. In addition, the device includes a drive element affixed to the first and second support elements, wherein rotation of the drive element causes a first rotation of the first and second rotating elements and thus the substrate about a center axis. This also causes a second rotation wherein the engagement of the sun gear and the planet gear causes simultaneous rotation of the substrate about the first axis.
