  • Patent number: 9281222
    Abstract: A wafer handling system may include upper and lower linked robot arms that may move a wafer along a nonlinear trajectory between chambers of a semiconductor processing system. These features may result in a smaller footprint in which the semiconductor processing system may operate, smaller transfer chambers, smaller openings in process chambers, and smaller slit valves, while maintaining high wafer throughput. In some embodiments, simultaneous fast wafer swaps between two separate chambers, such as load locks and ALD (atomic layer deposition) carousels, may be provided. Methods of wafer handling are also provided, as are other aspects.

    Abstract: Methods and apparatus are provided for the use of a dual Selective Compliant Assembly Robot Arm (SCARA) robot. In some embodiments two SCARAs are provided, each including an elbow joint, wherein the two SCARAs are vertically stacked such that one SCARA is a first arm and the other SCARA is a second arm, and wherein the second arm is adapted to support a first substrate, and the first arm is adapted to extend to a full length when the second arm supports the first substrate, and wherein the first substrate supported by the second arm is coplanar with the elbow joint of the first arm, and the second arm is further adapted to move concurrently in parallel (and/or in a coordinated fashion) with the first arm a sufficient amount to avoid interference between the first substrate and the elbow joint of the first arm. Numerous other embodiments are provided.

  • Patent number: 7039501
    Abstract: Generally, a method of determining a position of a robot is provided. In one embodiment, a method of determining a position of a robot comprises acquiring a first set of positional metrics, acquiring a second set of positional metrics and resolving the position of the robot due to thermal expansion using the first set and the second set of positional metrics. Acquiring the first and second set of positional metrics may occur at the same location within a processing system, or may occur at different locations. For example, in another embodiment, the method may comprise acquiring a first set of positional metrics at a first location proximate a processing chamber and acquiring a second set of positional metrics in another location. In another embodiment, substrate center information is corrected using the determined position of the robot.
