In general, there are two types of AMHS in the wafer
fab. The first is the interbay system, which is transporting cassettes or boxes of wafers between process bays. The
other is the intrabay system, which is transporting
cassettes or boxes of wafers within one process bay, also
called tool-to-tool AMHS. Interbay systems are typically
monorail-type movement systems, where vehicles
move material monorailand interface with AS/RS
machines (stockers) in bay areas where materials are
processed. Intrabay automation has been shown to
increase process equipment utilization and reduce the
labor requirement. Five types of intrabay systems
automation vehicles are being developed by material
handling equipment suppliers: rail robots, rail guided
vehicles, automated guided vehicles (AGV); personnel
guided vehicles, and overhead transport vehicles. The
analysis of an intrabay system can be found in
Cardarelli et al.
