  • 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.

  • Publication number: 20040076496
    Abstract: A system for opening a substrate carrier includes a substrate carrier having an openable portion. The substrate carrier also has an opening mechanism coupled to the openable portion. A substrate transfer location has a support adapted to support a substrate carrier. The substrate transfer location also has an actuator mechanism. The actuator mechanism is positioned relative to the support so as to interact with the opening mechanism of the substrate carrier. The actuator mechanism of the substrate transfer location and the opening mechanism of the substrate carrier are adapted to interface with each other at the substrate transfer location so as to employ movement of the substrate carrier to achieve opening and closing of the substrate carrier.

  • Publication number: 20040062633
    Abstract: In a semiconductor fabrication facility, a conveyor transports substrate carriers. The substrate carriers are unloaded from the conveyor and loaded onto the conveyor without stopping the conveyor. A load and/or unload mechanism lifts the substrate carriers from the conveyor during unloading operations, while matching the horizontal speed of the conveyor. Similarly, during loading operations, the load/unload mechanism lowers a substrate carrier into engagement with the conveyor while matching the horizontal speed of the conveyor. Individual substrates, without carriers, may be similarly loaded and/or unloaded from a conveyor.

  • Patent number: 6709218
    Abstract: The present invention generally provides a robot blade which provides a plurality of semi-conductive or conductive contacts disposed at least partially on the surface of the blade to support a substrate above the blade. The contacts are preferably located inwardly from the edge of the blade and toward the center of the blade to provide a collection area on the blade to capture any particles which may form. The blade is preferably made of a semi-conductive material, such as alumina or other semi-conductive material, to provide an electrical flow path through the contact(s) to discharge any electrical charge which may build up on the substrate during processing.

  • Publication number: 20030202865
    Abstract: A wafer handler having a central body with a first end and a central axis of rotation is provided. A first end effector, adapted to support a first wafer, is rotatably coupled to the first end of the central body so as to define a first axis of rotation between the central body and the first end effector. Optionally, a second end effector adapted to support a second wafer is rotatably coupled to the second end of the central body so as to define a second axis of rotation between the central body and the second end effector. When the central body is rotated about the central axis of rotation in a first direction over a first angular distance, the first end effector simultaneously rotates about the first axis of rotation and the optional second end effector rotates about the second axis of rotation. Both end effectors are rotated over a second angular distance that is greater than the first angular distance. One or more of the end effectors may be pocketless.

  • Publication number: 20030110649
    Abstract: A jig used in a substrate carrier handling robot calibration process has features that emulate the overhead transport flange and the bottom surface of a standard substrate carrier. The jig further includes features that are allowed to interact with sensors associated with substrate carrier storage locations and/or sensors associated with an end effector of the substrate carrier handling robot. In calibrating the substrate carrier handling robot the jig is juxtaposed with a substrate carrier storage location. The end effector of the robot is moved relative to the substrate carrier storage location and the above-mentioned sensors are allowed to interact with the jig. A controller for the robot detects locations of the end effector at times when the sensors interact with the jig.

    Abstract: A storage surface for a semiconductor substrate carrier has substrate carrier sensors that are integrated with locator pins. Each locator pin includes a pin body mounted on, and extending upwardly from, the surface. The pin body has a slot formed at an upper portion of the pin body. A paddle is mounted in the slot of the pin body and is adapted to be actuated in a downward direction when a substrate carrier is seated on the pin body. The pin body has an uppermost point, and when the paddle is unactuated, the paddle does not extend above the uppermost point of the pin body.
