    摘要: An apparatus including a drive having motors and coaxial drive shafts; an arm assembly having a first arm and a second arm; and a controller. The first arm includes a first upper arm, a first forearm, a first end effector, and a first transmission, where the first transmission includes a non-circular pulley, and where the first upper arm and the first forearm have unequal effective lengths. The second arm includes a second upper arm, a second forearm, a second end effector, and a second transmission, where the second upper arm and the second forearm have substantially equal effective lengths. The controller is configured to cause the drive to extend and retract the arms to move an upper substrate and a lower substrate on the substrate holding areas such that the arm assembly and upper substrate do not travel over the lower substrate.

    摘要: An apparatus including a first device configured to support at least one substrate thereon; and a first transport having the device connected thereto. The transport is configured to carry the device. The transport includes a plurality of supports which are movable relative to one another along a linear path; at least one magnetic bearing which at least partially couples the supports to one another. A first one of the magnetic bearings includes a first permanent magnet and a second magnet. The first permanent magnet is connected to a first one of the supports. A magnetic field adjuster is connected to the first support which is configured to move the first permanent magnet and/or vary influence of a magnetic field of the first permanent magnet relative to the second magnet.

    摘要: An apparatus including a movable arm; a robot drive connected to the movable arm; and a heat transfer system. The robot drive includes a first drive configured to extend and retract the movable arm and a second drive configured to move the movable arm and the first drive along a linear path. The heat transfer system includes a first heat transfer member on the base and a second heat transfer member, where the heat transfer system is configured to transfer heat from the first drive to the first heat transfer member and then from the first heat transfer member to the second heat transfer member. The first heat transfer member travels with the base, and the first heat transfer member moves relative to the second heat transfer member as the base moves relative to the slide.

    摘要: A transport apparatus including a robot drive; an arm having a first end connected to the robot drive; and at least one end effector connected to a second end of the arm. The arm includes at least three links connected in series to form the arm. The arm is configured to be moved by the robot drive to move the at least one end effector among load locks and two or more sets of opposing process modules.

    摘要: An apparatus including a robot drive, a first arm having a first upper arm, a first forearm and a first end effector, where the first end effector comprises a first and second substrate support sections and a leg located between the first and second support sections which connects the substrate support sections to a wrist joint with the first forearm, and where a connection of the leg to the wrist joint is offset unequal distances relative to respective centerlines of the first and second substrate support sections, and a second arm having a second upper arm connected to the robot drive, where the first and second upper arms are connected to a first shaft of the robot drive to be rotated in unison, and where the wrist joint does not intersect the drive axis while the first arm is being extended and retracted.

    摘要: Providing a first movement including rotating a first arm about a rotational axis of a robot drive; rotating a second arm on the first arm, where the first and second arms form a robot arm, where the first and second arms are the only arms of the robot arm, where the robot arm has an end effector rotationally fixed to the second arm, and where the end effector is configured to support a substrate thereon for transporting the substrate by the robot arm; and controlling the rotating to provide a path of the end effector such that the end effector does not contact the substrate during the rotating. Providing a second movement including rotating the arms to provide an at least partially straight linear path of a center of the substrate relative to the rotational axis of the drive robot when the substrate is on the end effector.
