Patent number: 7293950Abstract: The present invention is a wafer transfer system that transports individual wafers between chambers within an isolated environment. In one embodiment, a wafer is transported by a wafer shuttle that travel within a transport enclosure. The interior of the transport enclosure is isolated from the atmospheric conditions of the surrounding wafer fabrication facility. Thus, an individual wafer may be transported throughout the wafer fabrication facility without having to maintain a clean room environment for the entire facility. The wafer shuttle may be propelled by various technologies, such as, but not limited to, magnetic levitation or air bearings. The wafer shuttle may also transport more than one wafer simultaneously. The interior of the transport enclosure may also be under vacuum, gas-filled, or subject to filtered air.Type: GrantFiled: September 3, 2002Date of Patent: November 13, 2007Assignee: Aysts Technologies, Inc.Inventors: Anthony C.

Patent number: 7275905Abstract: A cassette position control device controls the position of a cassette in which wafers are stored, when the wafer cassette is loaded on a cassette support. In addition to the cassette support, the device has a cassette moving section and a control section. The control section senses the state of the wafer cassette on the cassette support, and generates and outputs a motor drive signal to move the cassette to a designated relative position on the cassette support. The cassette moving section moves the wafer cassette to the designated position in response to the motor drive signal. Therefore, wafers can be loaded/unloaded to and from the same designated position after the wafer cassette has been placed on a cassette support.Type: GrantFiled: April 14, 2005Date of Patent: October 2, 2007Assignee: Samsung Electronics Co., Ltd.Inventor: Jong-Haw Lee

Patent number: 7217076Abstract: The semiconductor material handling system is an EFEM that may either mount to the front end of a processing tool or be integrated into the processing tool. The EFEM is built from a unified frame that the EFEM components, such as a wafer engine and a SMIF pod advance plate, may mount to. The frame serves as a common mounting structure that the EFEM components may use as a reference for alignment purposes. Since the EFEM components do not have to align with respect to the position of each other, the calibration, if any is required, is greatly simplified. The EFEM also has a reduced footprint, allowing the EFEM to mount to the front end of a processing tool and not extend to the fab floor. Thus, space is freed up between the EFEM and the fab floor. By way of example only, this space may be used as a maintenance access area to the processing tool without having to first remove the EFEM.Type: GrantFiled: March 1, 2002Date of Patent: May 15, 2007Assignee: Asyst Technologies, Inc.Inventors: Anthony C.

Patent number: 6799932Abstract: A processor for processing articles, such as semiconductor wafers, in a substantially clean atmosphere is set forth. The processor includes an enclosure defining a substantially enclosed clean processing chamber and at least one processing station disposed in the processing chamber. An interface section is disposed adjacent an interface end of the enclosure. The interface section includes at least one interface port through which a pod containing articles for processing are loaded or unloaded to or from the processor. The interface section is hygienically separated from the processing chamber since the interface section is generally not as clean as the highly hygienic processing chamber. An article extraction mechanism adapted to seal with the pod is employed. The mechanism is disposed to allow extraction of the articles contained within the pod into the processing chamber without exposing the articles to ambient atmospheric conditions in the interface section.Type: GrantFiled: June 9, 2003Date of Patent: October 5, 2004Assignee: Semitool, Inc.Inventors: Jeffry A.

Patent number: 6764265Abstract: Embodiments of the present invention provide structures for reducing erosion of a slit valve utilized in the fabrication of semiconductor devices. Specifically, non-metallic slit valve components such as a compressible sealing member and a barrier that assist in sealing the valve closure against the slit valve seat, are positioned on the valve seat rather than on the valve closure. This orientation removes the seal and the seal barrier from the direct line of sight of the plasma within the processing chamber, reducing exposure of the sealing member and seal barrier slit valve components to erosion and thereby extending the lifetime of the valve.Type: GrantFiled: January 7, 2002Date of Patent: July 20, 2004Assignee: Applied Materials Inc.Inventors: Charles S.
