摘要: Cluster tools provide a flexible, reconfigurable, and efficient environment for semiconductor manufacturing. They become difficult to operate because of residency time constraints and process time variation. This talk addresses their modeling, scheduling and control issues. A generic Petri net model is developed to model them. It describes the robot activity sequence with robot waits included. Hence, to operate a cluster tool is to determine robot wait times. A two-level operational architecture is proposed and discussed. It includes an off-line periodic scheduler and real-time controller. This proposed approach allows a cluster tool to adapt to activity time variation while operate at its highest throughput at the steady-state. The Petri net models play a critical role in ensuring proper transient  processes and optimal steady-state operations of cluster tools.
