View Patent ↗In accordance with an exemplary embodiment a semiconductor workpiece processing system having at least one processing tool for processing semiconductor workpieces, a container for holding at least one semiconductor workpiece therein for transport to and from the at least one processing tool and a first transport section elongated and defining a travel direction. The first transport section has parts, that interface the container, supporting and transporting the container along the travel direction to and from the at least one processing tool. The container is in substantially continuous transport at a substantially constant rate in the travel direction, when supported by the first transport section. A second transport section is connected to the at least one process tool for transporting the container to and from the at least one processing tool.
1. A semiconductor workpiece processing system comprising:
at least one processing tool for processing semiconductor workpieces;
a container for holding at least one semiconductor workpiece therein for transport to and from the at least one processing tool;
a first transport section elongated and defining a travel direction, and having parts, that interface the container, supporting and transporting the container along the travel direction to and from the at least one processing tool, where a controller means is connected to the first transport section, the controller means and the first transport section being configured so that the container is in substantially continuous transport at a substantially constant rate in the travel direction, when supported by the first transport section;
at least one queue section; and
a second transport section connected to the at least one process tool for transporting the container between the at least one processing tool and the first transport section, the second transport section being separate and distinct from the first transport section and interfacing the first transport section through the at least one queue section for loading and unloading the container to and from the parts of the first transport section;
wherein the first transport section is a mass transport system with a distributed drive arranged to support and transport containers without transport vehicles, and the second transport section is a vehicle based system having a transport vehicle capable of holding and moving the container.
2. The system according to claim 1 , wherein the second transport section is connected to the at least one processing tool for loading and unloading the container to and from the at least one processing tool.
3. The system according to claim 1 , wherein the second transport section comprises a transport vehicle capable of holding and transporting the container in a travel direction defined by the second transport system, the transport vehicle being arranged to load and unload the container to and from the first transport system.
4. The system according to claim 3 , wherein the second transport section has a drive system arranged so that the transport vehicle of the second transport section is capable of travel in at least two travel directions angled relative to each other.
5. A semiconductor workpiece processing system comprising:
at least one processing tool for processing semiconductor workpieces;
a container for holding at least one semiconductor workpiece therein for transport to and from the at least one processing tool;
a first transport section elongated and defining a travel direction, and having parts, that interface the container, supporting and transporting the container along the travel direction to and from the at least one processing tool, where a controller means is connected to the first transport section, the controller means and the first transport section being configured so that the container travels at a substantially constant rate in the travel direction, when supported by the first transport section;
at least one queue section; and
a second transport section connected to the at least one process tool and first transport section interfacing the container between the at least one processing tool and first transport section, the second transport section being distinct from the first transport section and interfacing the first transport section through the at least one queue section for loading and unloading the container to and from the parts of the first transport section;
wherein the constant rate of travel of the container is substantially independent of an interface rate between the second transport section and the at least one processing tool;
wherein the first transport section is a mass transport system with a distributed drive arranged to support and transport containers without transport vehicles, and the second transport section is a vehicle based system having a transport vehicle capable of holding and moving the container.
