摘要:
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.

The present invention is a wafer engine for transporting wafers. The wafer engine includes a linear drive for moving the wafer along an x axis, a rotational drive for rotating the wafer about a theta axis, a linear drive for moving the wafer along a z axis, and a linear drive for moving the wafer along a radial axis. The linear drive for moving the wafer along a z axis is offset from the rotational drive. When the rotational drive rotates about the theta axis, both the z axis and radial axis drives are also rotated about the theta axis. Preferably, the linear drive for moving the wafer along a radial axis is a dual or rapid swap slide body mechanism having an upper and lower end effector. The slide body mechanism preferably also has means to align the wafer and perform various inspection and marking procedures.

A substrate support and transport system for substrates to be processed is provided. The system includes a container supporting a plurality of substrates in a substantially vertical orientation, where the container has an access door surrounded by a flange defined on a top surface. The system includes a conveying system supporting a bottom surface of the container opposing the top surface. The conveying system is configured to enable removal of the container from the conveying system to a processing tool while the plurality of substrates is in the substantially vertical orientation. The system further includes a receiving module for a processing tool configured to accept the container from the conveying system. The receiving module is configured to move the container in a two dimensional plane defined within the receiving module. A container holding the substrates in a substantially vertical orientation and a method for transporting and storing substrates is provided.

The present invention comprises a conveyor for moving a semiconductor containers throughout a fabrication facility. In one embodiment, the conveyor comprises a plurality of individually controlled conveyor zones. Each conveyor zone includes a first belt, a second belt, a drive assembly for rotating the first belt and the second belt at substantially the same speed. The first belt and the second belt are driven at substantially the same speed and movably support the container's bottom plate as the container moves along the conveyor. In another embodiment, the conveyor includes sensors to determine, among other things, the position of the container.

The present invention generally comprises a tool load device for transferring a container between a container transport system and a processing tool. The tool load device may service a single load port or multiple load ports. Regardless, the tool load device is preferably located between the load port of the processing tool and the section of the container transport system passing the processing tool. The tool load device provides an improved method of moving containers between a conventional load port and, for example, a conveyor. In another embodiment, the tool load device is coupled with an x-drive assembly that moves the tool load device along a path that is substantially parallel to the container transport system passing in front of the load port—allowing the tool load device to service multiple load ports.

The present invention comprises a load port for providing access to an article that is stored in a container having a container door removably coupled to a container shell. The load port preferably loads/unloads a container directly from a container transport system. In one embodiment, the load port includes a plate having an opening, a container support plate, a drive assembly for moving the support plate vertically and a shroud to partially enclose the opening. The shroud, which may be affixed to the mounting plate, has an open top and bottom. The shroud contains a mechanism for retaining the container shell at a controllable height. During operation, a container is raised from the transport system into the shroud until the container shell is retained by the mechanism. After the container shell is uncoupled from the container door, the container support plate is lowered until the article is accessible through the opening. The container shell remains located at the controllable height. The container shell, in combination with the shroud, creates a mini-environment isolating the article from ambient conditions in the fabrication facility.

A variable lot size load port assembly is described having a tool interface, a port door, a latch key, an advance plate, and an elevator. The tool interface extends generally in a vertical dimension and has an aperture. The port door has a closed position wherein the port door at least partially occludes the aperture. The latch key extends from the port door and is configured to mate with a latch key receptacle of a door of a front opening unified pod (FOUP). The advance plate is configured to support a front opening unified pod (FOUP) and translate between a retracted position and an advanced position. The elevator raises and lowers the advance plate to bring the latch key receptacle of the door of the FOUP into alignment with the latch key of the port door.

The present invention comprises a stocker for managing containers within a fabrication facility having a ceiling-based interbay material handling system a floor-based intrabay material handling system. In one embodiment, the stocker comprises a container storage area for storing at least one container, a ceiling-based input conveyor, a floor-based conveyor and a robotic mechanism. The ceiling-based input conveyor receives containers from the ceiling based interbay material handling system. The stocker's floor-based conveyor may comprise an output conveyor, an input conveyor or both, and moves containers between the stocker's container storage area and the floor-based intrabay material handling system. A robotic mechanism moves containers between the ceiling-based input conveyor, the container storage area and the floor-based conveyor.

A variable lot size load port assembly includes a tool interface, a port door, an advance plate, and first and second latch keys. The tool interface extends generally in a vertical dimension and has an aperture. The port door has a closed position wherein the port door at least partially occludes the aperture. The advance plate is configured to support a front opening unified pod (FOUP) and translate between a retracted position and an advanced position. The first latch key is disposed on the port door at a first elevation configured to selectively engage a corresponding latch key receptacle of a FOUP having a first selected FOUP capacity and the second latch key is disposed on the port door at a second elevation configured to selectively engage a corresponding latch key receptacle of another FOUP having a second selected FOUP capacity.
