  • Publication number: 20060130750
    Abstract: Embodiments generally provide an apparatus and method for processing substrates using a multi-chamber processing system (e.g., a cluster tool) that has an increased system throughput, increased system reliability, substrates processed in the cluster tool have a more repeatable wafer history, and also the cluster tool has a smaller system footprint. In one embodiment, the cluster tool is adapted to perform a track lithography process in which a substrate is coated with a photosensitive material, is then transferred to a stepper/scanner, which exposes the photosensitive material to some form of radiation to form a pattern in the photosensitive material, which is then removed in a developing process completed in the cluster tool.

    Abstract: In a first aspect, an automatic door opener is provided that includes (1) a platform adapted to support a substrate carrier; (2) a door opening mechanism adapted to open a door of the substrate carrier while the substrate carrier is supported by the platform; and (3) a tunnel. The tunnel is adapted to extend from an opening in a clean room wall toward the platform and at least partially surround the platform. The tunnel is further adapted to direct a flow of air from the clean room wall toward the platform and out of the tunnel. Numerous other aspects are provided.

  • Publication number: 20050224315
    Abstract: In a first aspect, a substrate loading station is served by a conveyor which continuously transports substrate carriers. A substrate carrier handler that is part of the substrate loading station operates to exchange substrate carriers with the conveyor while the conveyor is in motion. A carrier exchange procedure may include moving an end effector of the substrate carrier handler at a velocity that substantially matches a velocity of the conveyor. A balancing mass is coupled directly or indirectly to a frame on which the substrate carrier handler is mounted and is adapted to accelerate in a direction opposite to the direction of end effector acceleration, as the end effector accelerates. Thus, inertial loads may be substantially balanced, and frame vibration reduced, despite potentially high rates of acceleration. Numerous other aspects are provided.

  • Publication number: 20050167554
    Abstract: A kinematic pin and a substrate carrier adapted to deter dislodgment of the substrate carrier from the kinematic pin are provided. A shear member on the kinematic pin interacts with a shear feature of the substrate carrier to deter lateral movement of the substrate carrier relative to the kinematic pin. A substrate carrier handler that employs the kinematic pin is also provided.

  • Publication number: 20050145464
    Abstract: In a first aspect, a first apparatus is provided for inter-station overhead transport of a substrate carrier. The first apparatus includes (1) an overhead transport mechanism; (2) a substrate carrier support suspended from the overhead transport mechanism and adapted to receive and support a substrate carrier; and (3) a stabilization apparatus adapted to limit rocking of the substrate carrier and substrate carrier support relative to the overhead transport mechanism. Numerous other aspects are provided.

  • Publication number: 20050135903
    Abstract: In a first aspect, a wafer loading station adapted to exchange wafer carriers with a wafer carrier transport system comprises a biasing element adapted to urge the end effector of the wafer loading station away from a moveable conveyor of the wafer carrier transport system upon the occurrence of a unscheduled event such as a power failure or an emergency shutdown. In a second aspect, an uninterruptible power supply commands a controller to cause the wafer carrier handler to retract the end effector from the wafer carrier transport system upon the occurrence of the unscheduled event, and provides the power necessary for the same. Numerous other aspects are provided.

  • Publication number: 20050133365
    Abstract: A lift mechanism for and a corresponding use of a magnetron in a plasma sputter reactor. A magnetron rotating about the target axis is controllably lifted away from the back of the target to compensate for sputter erosion, thereby maintaining a constant magnetic field and resultant plasma density at the sputtered surface, which is particularly important for stable operation with a small magnetron, for example, one executing circular or planetary motion about the target axis. The lift mechanism can include a lead screw axially fixed to the magnetron support shaft and a lead nut engaged therewith to raise the magnetron as the lead nut is turned. Alternatively, the support shaft is axially fixed to a vertically moving slider. The amount of lift may be controlled according a recipe based on accumulated power applied to the target or by monitoring electrical characteristics of the target.

  • 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: 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.
