摘要:
Disclosed is a manipulator for removing a cassette holding articles, such as semiconductor wafers, to be processed from a container supported on a processing station in a standard mechanical interface (SMIF) system. The container is supported on an interface port on the canopy of the processing station and has a removeable door on which the cassette is supportable. A first platform is transportable along a shaft below the interface port and is operable to mate with the interface port and receive the cassette from the container. The first platform is transported down the shaft, thereby removing the cassette from the container. A second platform mounted in the shaft includes a manipulator arm which swings to engage the cassette on the first platform and support the cassette off of the first platform. The manipulator arm then pivots to transport the cassette to a location in the processing station away from the shaft. The first platform is then transported back up the shaft to the interface port to seal the container to prevent particulate contamination. The manipulator arm and the second platform after placing the cassette at a location in the processing station away from the shaft, are then positioned completely inside the shaft to minimize the space taken up in the processing station by the manipulator.

Infrared radiation is focused to a line at a site at which a semiconductor wafer is expected to appear when a wafer is transferred with, i.e., loaded onto or unloaded from, a semiconductor wafer conveyor. A cylindrical lens of selected focal length is positioned to receive and focus to a line at an image plane radiation reflected by a wafer arriving at the site. An apertured stop defines an opening at the image plane to pass reflected radiation to an infrared sensor positioned on the side of the stop opposite the cylindrical lens.

A kickstand for supporting a parked two-wheeled vehicle and a footrest for supporting the feet of the vehicle operator when the vehicle is in motion is provided by a single device comprising a lever pivoted about an axis parallel to the longitudinal axis of the vehicle on a horizontal beam rigidly affixed to the vehicle frame. The center of gravity of the lever portion is located relative to the pivot axis so that the lever portion is stable both when pivoted to contact the ground for vehicle support and when pivoted to a position parallel to the beam to act as a footrest.

A workpiece container storage and handling system includes a base, a number of wheels connected to the base, and a container handling system connected to the base. The wheels provide for movement of the base. The container handling system is defined to hold at least two containers in a vertically overlying orientation relative to each other. The container handling system is defined to provide for controlled vertical travel of the at least two containers in unison relative to the base. Also, the container handling system is defined to provide for controlled and independent horizontal travel of each of the at least two containers relative to the base.

A tray engine includes a vertical drive column, a rotation mechanism for rotating the vertical drive column, and an end effector attached to the vertical drive column. The end effector includes an end effector base attached to the vertical drive column. The end effector further includes a slide attached to the end effector base to support a tray, when present. The slide enables the tray to slide along a length of the end effector base. The tray engine includes a drive mechanism attached to the end effector base for moving along the length of the end effector base to enable the tray, when present, to slide linearly along the length and load or unload the tray to or from the slide.

An end effector having a first arm and a second arm extending from an end effector support body is provided. The first arm and the second arm each have support extensions for supporting a peripheral region of a substrate on opposing sides of a diameter of the substrate. The height of support contacts on opposing sides of the diameter is different relative to a horizontal datum plane. In one embodiment, the end effector includes additional arms extending from the end effector support body. A system for supporting a substrate is provided also.

The present invention generally comprises an apparatus for transporting containers between a first transport system and a second transport system. In one embodiment, the first transport system comprises a ceiling-based conveyor and the second transport system comprises a floor-based conveyor. The present invention may further include storage shelves, preferably substantially horizontally aligned about a common vertical plane with a section of one of the transport systems. The transport system may be located either directly above the uppermost storage shelf or beneath the lowermost storage shelf in order to add storage capacity within the fab. A vertical module transports containers between the transport systems and the at least one storage shelf.

A direct load system and conveyor is disclosed. The direct load system includes a load port for moving containers in a vertical orientation between a lower position near the conveyor and up to an upper position proximate to a load port door. The load port includes a single arm that moves a support in a vertical configuration, such that moving the single arm allows for the support to be lowered to the conveyor in a nested location between beams of the conveyor. The conveyor includes a single slot in a beam that allows the single arm to pass, and allows the support to be placed in the nested location, which is below a conveyor path defined by the belts of the conveyor. If a container is to be lifted off of the belts, the single arm raises up from the nested location, to then raise the container up and off of the conveyor and to the load port door. The single arm and interface with the conveyor slot can be used by other tools, such as stockers or tools that need to directly access a conveyor used to transport containers (e.g., wafers, etc.) to locations/tools of a fabrication facility. In alternate embodiments, it is possible to replace the belt with conveying wheels.

The present invention comprises a vacuum end effector having workpiece supports that work in conjunction with distorted workpiece surfaces. In one embodiment, each workpiece support has the ability to gimbal and conform the workpiece surface in contact with an outer edge of the support. Each workpiece support preferably provides a knife-like contact edge to minimize the contact area between the support and the workpiece while still providing an effective vacuum area to hold the wafer securely on the support. In another embodiment, each workpiece support is replaceable without having to remove the end effector from the robot assembly.
