| 英文摘要 |
| For some semiconductor fabrication processes in cluster tools, wafer revisiting is a typical and complicate process. Analysis and optimization of the transient process is of great significance for wafer processing. Based on the Petri net and 1-wafer cyclic schedule, in order to meet processing requirements and improve processing performance of cluster tools, the final transient process for dual-arm cluster tools with wafer revisiting is analyzed by using virtual wafer processing mode. Then, the processing time of final transient process in different conditions is described by some expressions. For final transient process with wafer revisiting to be analyzed more intuitively, a simulation model is developed by using eMPlant as a simulation platform. With this model, illustrative examples are given to show the feasibility of 1-wafer cyclic schedule and effectiveness of the expressions. Thus, the simulation model provides an effective tool for researchers to study the optimization of wafer fabrication with revisiting. |
