摘要:
A transfer system and method for moving an article between a conveyor and a workstation. The transfer system includes an elevator system having a lift device configured to engage the article carried by a conveyor and raise the article above the conveyor. The lift device is movable between a stand-by position with the lift device positioned for the movement of articles past the lift device along the conveyor, and an actuated position with the lift device holding the article above the conveyor. The transfer system also includes a support assembly for supporting the article vicinal a workstation. The support assembly including a shelf for retaining the article at the workstation and a displacement mechanism for moving the shelf between the conveyor and the lift device. The method includes moving a support to engage the article and lift the article above the conveyor, extending a load port shelf to the conveyor and inserting the shelf between the article and the conveyor. After the shelf is extended, the method includes moving the support to deposit the article onto the shelf, and after the step of moving the support, the method includes retracting the shelf to the load port.

An integrated intra-bay transfer, storage and delivery system is provided for moving an article between a conveyor and a station such as a work station. The system includes a transfer assembly which includes a lift mechanism and a displacement mechanism. The transfer assembly transfers the article between the conveyor system and a buffer or storage station for storage of the article. A delivery robot transfers the article between the buffer or storage station and a work station for delivery to the station. The robot includes a vertical movement mechanism and a horizontal movement mechanism. The robot also includes an arm that is adapted to grip the article, particularly an article of a standard configuration having a mushroom-shaped handle on top. The arm engages the handle and lifts the article or transport pod from the storage station to a load port of the work station. In one embodiment, the arm includes a C-shaped adaptation that passively engages the handle from a side thereof. In other embodiments, the arm includes an actuator coupled to an assembly that actively grips the handle from above. Advantages of the invention include the ability to safely move the transport pod from a elevated storage station to the lower placed storage stations or load ports of a work station.

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.

The present invention is a unified spine structure that EFEM components, such as a wafer handling robot and a SMIF pod advance assembly, may mount to. The frame includes multiple vertical struts that are mounted to an upper support member and a lower support member. Structurally tying the vertical struts to the support members creates a rigid body to support the EFEM components. The vertical struts also provide a common reference that the EFEM components may align with. This eliminates the need for each EFEM component to align with respect to each other. Thus, if one EFEM component is removed it will not affect the alignment and calibration of the remaining secured EFEM components. The unified frame also creates an isolated storage area for the SMIF pod door and the port door within the environment that is isolated from the outside ambient conditions.

An integrated system is disclosed for workpiece handling and/or inspection at the front end of a tool. The system comprises a rigid member of unitary construction such as a metal plate which mounts to the front of a tool associated with a semiconductor process. The front end components, including the load port assemblies, prealigners and workpiece handling robot, are mounted to the plate to provide precise and repeatable positioning of the front end components with respect to each other.

A system for transporting articles. The transport system includes a conveyor system which includes a transport device for carrying articles between workstations and a drive rail and a support rail for supporting the transport device. The drive rail includes a drive system for propelling the transport device between workstations. At least one shoe carried by the transport device rides on the support rail for movably supporting the transport device on the support rail. The transport system also includes a protective container including a housing having an interior compartment for supporting a plurality of articles. The bottom surface of the housing is configured to engage the drive system such that actuation of the drive system propels the housing along the drive and support rails. At least one shoe carried by the housing is configured to ride on the support rail of the conveyor system to movably support the housing on the support rail. The transport system also includes the method of transporting articles including the steps of providing a transport device for holding at least one article and having at least one shoe, positioning the transport device with the base of the device supported on a drive rail and the shoe supported on a support rail, and actuating a drive system carried by the drive rail to propel the transport device along the drive rail and support rail.

A storage system and methods for operating a storage system are disclosed. The storage system includes a storage system assembly positioned at a height that is greater than a height of a tool used for loading and unloading substrates to be processed. The storage system locally stores one or more containers of substrates. The storage system assembly includes a plurality of storage shelves, and each of the plurality of storage shelves have shelf plates with shelf features for supporting a container. Each of the plurality of storage shelves are coupled to a chain to enable horizontal movement and each is further coupled to a rail to enable guiding to one or more positions. A motor is coupled to a drive sprocket for moving the chain, such that each of the plurality of storage shelves move together along the rail to the one or more positions. The rail has at least some sections that are linear and some sections that are nonlinear and the sections are arranged in a loop. Example configurations of the storage system can include one or more of stationary shelves, extended horizontal tracks for hoists, conveyors at the level of the storage system assembly, and a manual loading station. The hoist, with an extended horizontal track can therefore interface with the manual loading station.
