    摘要: A system for sensing, orienting, and transporting wafers in an automated wafer handling process that reduces the generation of particles and contamination so that the wafer yield is increased. The system includes a robotic arm for moving a wafer from one station to a destination station, and an end-effector connected to an end of the robotic arm for receiving the wafer. The end-effector includes a mechanism for gripping the wafer, a direct drive motor for rotating the wafer gripping mechanism, and at least one sensor for sensing the location and orientation of the wafer. A control processor calculates the location of the center and the notch of the wafer based on measurements by the sensor(s) and generates an alignment signal for rotating the wafer gripping mechanism so that the wafer is oriented at a predetermined position on the end-effector while the robotic arm is moving to another station.

    摘要: A time-optimal trajectory generation method, for a robotic manipulator haying a transport path with at least one path segment, comprising generating a forward time-optimal trajectory of the manipulator along the at least one path segment from a start point of the at least one path segment towards an end point of the at least one path segment, generating a reverse time-optimal trajectory of the manipulator along the at least one path segment from the end point towards the start point of the at least one path segment, and combining the time-optimal forward and reverse trajectories to obtain a complete time optimal trajectory, where the forward and reverse trajectories of the at least one path segment are blended together with a smoothing bridge joining the time-optimal forward and reverse trajectories in a position-velocity reference frame with substantially no discontinuity between the time-optimal forward and reverse trajectories.

    摘要: A loadport has a port door and a frame with an opening through which the port door interfaces with a container door of a container for holding semiconductor workpieces. In one embodiment, a movable closure mechanism is connected to the port door and is defined to be movable in a controlled manner relative to both the port door and the frame. In this embodiment, a stationary closure mechanism is disposed on the frame proximate to the opening. In another embodiment, a stationary closure mechanism is connected to the port door, and a movable closure mechanism is disposed on the frame proximate to the opening. In both embodiments, the movable closure mechanism is defined to engage with the stationary closure mechanism such that movement of the movable closure mechanism to engage with the stationary closure mechanism applies a closing force between the port door and the container door.

    摘要: A robot assembly for transporting a substrate is presented. The robot assembly having a first arm and a second arm supported by a column, the first arm further having a first limb, the first limb having a first set of revolute joint/line pairs configured to provide translation and rotation of the distal most link of the first limb in the horizontal plane. The assembly further having a second arm further having a second limb, the second limb comprising a second set of revolute joint/link pairs configured to provide translation and rotation of a distalmost link of the second limb in the horizontal plane. The first limb and second limb further having proximal revolute joints having a common vertical axis of rotation and a proximal inner joint housed in a common housing. The assembly further having an actuator assembly coupled to the first set of revolute joint/link pairs and to the second set of revolute joint/link pairs to effect rotation and translation of the distalmost links of the first limb and the second limb, each of the first limb and the second limb defining, in conjunction with the actuator assembly, at least three degrees of freedom per limb, whereby the distalmost links of the first limb and the second limb are independently horizontally translatable for extension and retraction.
