Publication number: 20070144439Abstract: The present invention generally provides an apparatus and method for processing substrates using a multi-chamber processing system (e.g., a cluster tool) that is easily configurable, has an increased system throughput, increased system reliability, improved device yield performance, a more repeatable wafer processing history (or wafer history), and a reduced 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, and then certain portions of the photosensitive material are removed in a developing process completed in the cluster tool.Type: ApplicationFiled: September 8, 2006Publication date: June 28, 2007Inventors: Eric A.

Patent number: 7234584Abstract: 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.Type: GrantFiled: August 28, 2003Date of Patent: June 26, 2007Assignee: Applied Materials, Inc.Inventors: Michael Robert Rice, Robert B. Lowrance, Martin R. Elliott, Jeffrey C. Hudgens, Eric A. Englhardt

Patent number: 7230702Abstract: 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.Type: GrantFiled: November 12, 2004Date of Patent: June 12, 2007Assignee: Applied Materials, Inc.Inventors: Michael R.

Patent number: 7221993Abstract: In a first aspect, a method of managing work in progress within a small lot size semiconductor device manufacturing facility is provided. The first method includes providing a small lot size semiconductor device manufacturing facility having (1) a plurality of processing tools; and (2) a high speed transport system adapted to transport small lot size substrate carriers among the processing tools. The method further includes maintaining a predetermined work in progress level within the small lot size semiconductor device manufacturing facility by (1) increasing an average cycle time of low priority substrates within the small lot size semiconductor device manufacturing facility; and (2) decreasing an average cycle time of high priority substrates within the small lot size semiconductor device manufacturing facility so as to approximately maintain the predetermined work in progress level within the small lot size semiconductor device manufacturing facility. Numerous other aspects are provided.Type: GrantFiled: January 26, 2004Date of Patent: May 22, 2007Assignee: Applied Materials, Inc.Inventors: Michael R. Rice, Eric A. Englhardt, Vinay Shah, Martin R.

Patent number: 7218983Abstract: In at least one aspect, the invention provides an electronic device fabrication facility (Fab) that uses small lot carriers that may be transparently integrated into an existing Fab that uses large lot carriers. A manufacturing execution system (MES) may interact with the inventive small lot Fab as if the small lot Fab is any other Fab component in an existing large lot Fab without requiring knowledge of how to control small lot Fab components (e.g., beyond specifying a processing recipe). A small lot Fab according to the present invention may encapsulate the small lot Fab's internal use of small lot components and present itself to a large lot Fab's MES as if the small lot Fab is a component that uses large lot carriers.Type: GrantFiled: November 4, 2004Date of Patent: May 15, 2007Assignee: Applied Materials, Inc.Inventors: Amitabh Puri, David Duffin, Eric A.

Patent number: 7168553Abstract: 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.Type: GrantFiled: November 12, 2004Date of Patent: January 30, 2007Assignee: Applied Materials, Inc.Inventors: Michael R. Rice, Eric A. Englhardt, Robert B. Lowrance, Martin R. Elliott, Jeffrey C. Hudgens

Patent number: 7156221Abstract: 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.Type: GrantFiled: November 12, 2004Date of Patent: January 2, 2007Assignee: Applied Materials, Inc.Inventors: Michael R.

Patent number: 5476548Abstract: 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.Type: GrantFiled: June 20, 1994Date of Patent: December 19, 1995Assignee: Applied Materials, Inc.Inventors: Lawrence C.
