By providing a space-efficient transfer buffer system in a manufacturing environment, which may act as a local interface between an automated transport system and the load port assembly of a process tool under consideration, the I/O capability of the process tool may be significantly enhanced, while not unduly contributing to the overall width of the process tools. In particular embodiments, an array-like arrangement of respective buffer places is used, wherein each buffer place is accessible by the transport system and may also interact with each of the load ports of the process tool.

Two-dimensional transfer station used as interface between a process tool and a transport system and a method of operating the same

By providing an overhead buffer system between an automatic transport system and a load port assembly of a process tool, the efficiency of the respective load ports may be significantly enhanced, for instance, by reducing the idle time of empty carriers, thereby providing the potential for covering a wider range of operational scenarios compared to conventional strategies. For instance, for the same number of load ports, the overhead buffer system may provide a continuous operation, even if small lot sizes are used. The buffer system may comprise a dedicated transport mechanism for directly serving the load ports and respective buffer places, while respective transfer places may provide direct interaction with the automated transport system.
