Abstract: The present invention generally comprises a transport system for transporting containers throughout a fabrication facility, and more specifically through a tool bay in the fabrication facility. The present invention generally includes a first container transport system for transporting a container from an interbay conveyor towards the first tool bay, a second container transport system for moving a container away from the first tool bay and a tool loading device to move containers between the first and second container transport systems and a load port. A merged return conveyor for transporting a container between the second container transport system and the interbay conveyor may also be included.

Abstract: A variable-size load port includes a port door defined to cover an effective aperture of the load port. A vertical positioning device is connected to the port door to provide for controlled vertical positioning and movement of the port door without substantial horizontal movement of the port door. A seal plate is disposed above the port door. The seal plate is defined to form a proximity seal with an upper surface of the port door when the port door is vertically positioned in proximity to the seal plate. The seal plate is defined to be adjustable in a vertical direction.
