Patent number: 7249925Abstract: A substrate protection and transport system and method for transitioning a substrate from atmospheric pressure to vacuum in a lithography tool. The system includes one or more removable substrate transport cassettes that support a substrate. The cassette can include a base portion and top portion, and can include a seal. Each cassette has at least one vent and at least one filter. The system further includes a box having a base and lid. The box holds one or more cassette-substrate arrangements. A storage rack having shelves for holding the box-cassette-substrate arrangement is also provided. Further, an entry-exit module having a loadlock is provided for transitioning the cassette-substrate arrangement from atmospheric pressure to vacuum. The entry-exit module can include a shuttle and/or elevator for transporting the cassette-substrate arrangement.Type: GrantFiled: November 21, 2005Date of Patent: July 31, 2007Assignee: ASML Holding N.V.Inventors: Santiago E. del Puerto, Michael A. DeMarco, Glenn M. Friedman, Jorge S. Ivaldi, James A. McClay

Patent number: 7214027Abstract: Systems and methods for handling wafers include retrieving a first wafer from a wafer cassette using a first arm, transferring the first wafer from the first transfer arm to a second arm, delivering the first wafer for processing to a process chamber using the second arm, removing the first wafer from the process chamber using the first arm, and returning the first wafer to the cassette using the first arm. The systems and methods can include retrieving a first wafer from a wafer cassette using a first arm, delivering the first wafer for processing to a process chamber using the first arm, removing a processed wafer from the process chamber using a second arm, returning the processed wafer to the cassette using the second arm, and iteratively retrieving, delivering, removing and returning wafers from the cassette while alternating arms between iterations.Type: GrantFiled: October 16, 2003Date of Patent: May 8, 2007Assignee: Varian Semiconductor Equipment Associates, Inc.Inventor: Stanley W. Stone

Patent number: 7141809Abstract: A method for reciprocally transporting a workpiece on a scan arm through an ion beam is provided, wherein the scan arm is operably coupled to a motor comprising a rotor and stator that are individually rotatable about a first axis. An electromagnetic force applied between the rotor and stator rotates the rotor about the first axis and translates the workpiece through the ion beam along a first scan path. A position of the workpiece is sensed and the electromagnetic force between the rotor and stator is controlled in order to reverse the direction of motion of the workpiece along the first scan path, and wherein the control is based, at least in part, on the sensed position of the workpiece. The stator further rotates about the first axis in reaction to the rotation of the rotor, particularly in the reversal of direction of motion of the workpiece, thus acting as a reaction mass to the rotation of one or more of the rotor, scan arm, and workpiece.Type: GrantFiled: April 5, 2005Date of Patent: November 28, 2006Assignee: Axcelis Technologies, Inc.Inventors: John W. Vanderpot, John D. Pollock, Donald W. Berrian

Patent number: 7135691Abstract: A reciprocating drive system and apparatus for scanning a workpiece through an ion beam are provided, wherein a motor comprising a rotor and stator operable to individually rotate about a first axis is operable to reciprocally translate the workpiece with respect to the ion beam. A shaft rotatably driven by the rotor extends along the first axis, and a scan arm is operably coupled to the shaft, wherein the scan arm is operable to support the workpiece thereon. Cyclical counter rotations of the shaft by the motor are operable to rotate the scan arm, therein scanning the workpiece through the ion beam along a first scan path, wherein the stator acts as a reaction mass to the rotation of the rotor. A controller is further operable to control an electromagnetic force between the rotor and the stator, therein generally determining a rotational position of the rotor and the stator.Type: GrantFiled: April 5, 2005Date of Patent: November 14, 2006Assignee: Axcelis Technologies, Inc.Inventors: John W.

Patent number: 7077614Abstract: Sorting/storage device for wafers. A sorting device is provided in which at least two cassettes containing wafers may be present and the wafers are moved from one cassette to the other cassette or vice versa. If appropriate, a measuring station may be present in the sorting device. In the immediate vicinity of the sorting device, the cassettes are stored in a magazine which is designed for this purpose and the cassettes are moved using a handling device for cassettes.Type: GrantFiled: September 21, 1999Date of Patent: July 18, 2006Assignee: ASM International N.V.Inventors: Albert Hasper, Sebastiaan Eliza Nooten, Menso Hendriks

Patent number: 7074000Abstract: 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.Type: GrantFiled: December 31, 2002Date of Patent: July 11, 2006Assignee: Applied Materials, Inc.Inventor: Eric A. Englhardt
