  • Publication number: 20050122504
    Abstract: A movable portion of a substrate carrier handler is extended into a transport path along which a substrate carrier transport system transports a substrate carrier, respective kinematic coupling events are detected between corresponding interface elements of the movable portion and the substrate carrier, respective signals are generated in response thereto, and an alignment offset between the substrate carrier and the substrate carrier transport system is determined based on the signals. A movable portion matches an elevation, position, and/or a speed/velocity of a substrate carrier moving along the transport path. Sensors for detecting kinematic coupling and generating signals in response thereto are provided on the movable portion. An end effector includes a support with interface elements and sensors for detecting kinematic coupling and generating respective signals.

  • Publication number: 20050121293
    Abstract: A break-away mounting system for a continuous-motion, high-speed position conveyor system is disclosed. A support cradle may be suspended from a conveyor belt such that the support cradle maintains a fixed position and orientation relative to at least one point on the conveyor belt without inducing appreciable stress on the conveyor belt, the support cradle, or the coupling between the conveyor belt and the support cradle. The mount may include a leading rotatable bearing attached to the support cradle which may releasably engage a first key attached to the conveyor belt, the rotatable bearing adapted to accommodate rotational forces applied to the support cradle by the conveyor belt. The mount may also include a slide bearing attached to the support cradle which may releasably engage a second key attached to the conveyor belt, the slide bearing adapted to accommodate longitudinal forces applied to the support cradle by the conveyor belt.

  • Publication number: 20050105997
    Abstract: A substrate carrier is counterbalanced so that the center of gravity of the carrier is aligned with the center of gravity of any substrates that the carrier may hold. In some embodiments, substrate supports disposed within the carrier are adapted to hold substrates such that the center of gravity of the substrates are aligned with the center of gravity of the carrier. A flange may be coupled to the carrier so as to provide a means to apply a net lifting or support force to the carrier that is aligned with the center of gravity of the carrier.

  • Publication number: 20040126207
    Abstract: A pod loading station includes a docking mechanism adapted to move a pod between a docked position and an undocked position, and a door opener adapted to unlatch and open a pod door from the pod. A controller is coupled to the docking mechanism and the door opener and is programmed to cause the pod to move from the docked position to the undocked position, and then to cause the pod to move back to the docked position so that it can be determined whether the pod door is properly closed prior to completing the removal of the pod from the pod loading station.

  • Publication number: 20040099215
    Abstract: The construction of a film on a wafer, which is placed in a processing chamber, may be carried out through the following steps. A layer of material is deposited on the wafer. Next, the layer of material is annealed. Once the annealing is completed, the material may be oxidized. Alternatively, the material may be exposed to a silicon gas once the annealing is completed. The deposition, annealing, and either oxidation or silicon gas exposure may all be carried out in the same chamber, without need for removing the wafer from the chamber until all three steps are completed. A semiconductor wafer processing chamber for carrying out such an in-situ construction may include a processing chamber, a showerhead, a wafer support and a rf signal means. The showerhead supplies gases into the processing chamber, while the wafer support supports a wafer in the processing chamber.

  • 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: 5476548
    Abstract: A substrate processing apparatus for processing a substrate having a peripheral edge, an upper surface for processing and a lower surface lying on a support. The apparatus includes a processing chamber which houses the substrate support, in the form of a heater pedestal including a substrate receiving surface for receiving the lower surface of the substrate. A circumscribing shadow ring is located around the pedestal to cover peripheral edge portion of the substrate. The shadow ring also defines a cavity, between itself and the pedestal, at the peripheral edge of the substrate. In operation, the chamber receives processing gas at a first pressure and purge gas is introduced into the cavity, between the ring and the pedestal, at a second pressure which is greater than the first pressure. Fluid conduits are provided to enhance the flow of the purge gas away from the peripheral edge of the substrate.
