  • Publication number: 20220415690
    Abstract: An aligner system includes a motor, a rotating device, a control device, and a sensor. The motor generates a rotational drive force. The rotating device 11 is rotated by the rotational drive force generated by the motor, while supporting a wafer. The control device controls rotation of the rotating device, and performs a process of setting a rotational phase of the wafer to a predetermined value. The sensor emits a plurality of light beams traveling in different directions toward an edge of the wafer, and receives the light beams to detect a defect in the edge of the wafer.

  • Publication number: 20220399218
    Abstract: A transport system includes a robot, sensors (an aligner sensor, a protrusion detecting sensor) and a controller. The robot having a hand which supports a wafer and transports the wafer to an aligner apparatus. The sensor detects the position of the wafer before the robot delivers the wafer to the aligner apparatus while supporting the wafer on the hand. The controller determines the positional deviation of the wafer based on a detection value of the sensor.

  • Publication number: 20220395986
    Abstract: Disclosed are techniques and systems for automatically determining and correcting the levelness of a wafer handling robot end effector. The systems may use a tilt sensor or a gravitational field sensor which may be calibrated to the wafer handling robot. The output from the tilt sensor may be used to determine or estimate the tilt of an end effector of the wafer handling robot and to perform correctional positioning to reduce or eliminate the tilt, to automatically teach certain positions that have reduced tilt, to perform health checks on the robot, provide feedback to a user, etc.

  • Patent number: 11335578
    Abstract: A substrate transfer apparatus of the present invention includes: a robot including a hand configured to hold a substrate, and an arm configured to move the hand; a robot control device configured to set a moving path for the hand and control the arm such that the hand moves on the moving path toward a target position; and a camera disposed so as to be able to capture an image of the substrate held by the hand located at a predetermined confirmation position. The robot control device sets the moving path so as to pass through the confirmation position, obtains an image captured by the camera when the hand is located at the confirmation position, calculates a distance between a predetermined environment and the substrate which are taken in the image, and calculates a positional deviation amount from a reference position of the substrate on the basis of the distance.

  • Patent number: 10509052
    Abstract: A test wafer having two spaced-apart accelerometers mounted thereon is disclosed. The accelerometers may be positioned at locations located along a common axis passing through the center of gravity of the test wafer. The test wafer may include a controller that may be used to transmit acceleration data collected by the accelerometers to another device. In some implementations, a semiconductor processing tool is provided that includes a test wafer receptacle for storing a test wafer that remains with the semiconductor processing tool and that may be retrieved by a wafer handling robot for performing a test cycle during periods when the wafer handling robot is not performing substrate transport operations.

  • Patent number: 9002504
    Abstract: The present disclosure is directed to methods and systems for evaluating wafer size handling capabilities of wafer handling robots and wafer stations in a wafer processing environment. In one embodiment, a method is provided in which size parameters for each of one or more wafer stations and one or more robot hands of a wafer handling robot are set based on user input. A user command identifying a desired robot hand and a desired wafer station is received. A first size parameter of the desired robot hand is compared to a second size parameter of the desired wafer station. If the first size parameter is equal to the second size parameter, or if the second size parameter is an all-size parameter, the user command is executed. If the first size parameter is not equal to the second size parameter, an error is generated.
