An integrated intrabay buffer, delivery, and stocker system including a pair of shuttles, capable, by themselves, of transferring a pod in an X-Z plane between the interbay transport system, the I/O ports of various process tools and a plurality of storage shelves provided along the wall of the tool bay. Advantageously, the present invention integrates together the process tools within a tool bay by providing a single transport mechanism shared by each tool, and by providing a single, large storage and buffer area for pods that is shared by each tool. This increases reliability and flexibility, and simplifies the hardware and software control. Additionally, the storage shelves may be provided above some or all of the process tools within the tool bay. Such an arrangement offers a substantially greater number of spaces to store a pod as compared to conventional tool bays. Moreover, as the space above processing tools is currently unused, in part because a clear, unobstructed path above the I/O ports of the processing tools must be available in conventional systems, the increased storage capacity according to the present invention may be provided without increasing the footprint of conventional tool bays.
A system for storing a plurality of pods within at least a section of a tool bay and for transferring said plurality of pods around within the tool bay, the tool bay including a plurality of process tools, said system comprising:
A transport system within at least a section of a processing tool bay including a plurality of semiconductor processing tools and a plurality of storage locations, the transport system, comprising:
A processing tool bay within a semiconductor fabrication site, at least a section of the processing tool bay comprising:
A transport system within a semiconductor fabrication site, the site including a plurality of processing tool bays, and an interbay transport system for transferring a substrate-carrying container to a delivery position within a processing tool bay of the plurality of processing tool bays, the processing tool bay further including a plurality of semiconductor processing tools and a plurality of storage locations, the transport system comprising:
A processing tool bay within a semiconductor fabrication site, at least a section of the processing tool bay comprising:
A processing tool bay within a semiconductor fabrication site, the processing tool bay including a plurality of processing tools for processing substrates, each processing tool of said plurality of processing tools including an input/output port for transfer of a substrate-carrying container into and out of said each processing tool, at least a section of the processing tool bay comprising:
A processing tool bay within a semiconductor fabrication site, the processing tool bay including a plurality of processing tools for processing substrates, each processing tool of said plurality of processing tools including an input/output port for transfer of a substrate-carrying container into and out of said each processing tool, at least a section of the processing tool bay comprising:
