Abstract

The semiconductor industry is highly competitive, and with the recent chip shortage, the throughput of wafers has become more important than ever. One of the tools that the industry has deployed is to use of quad-station modules instead of the traditional single-station modules that allow for higher throughput and better wafer consistency by processing multiple wafers at the same time and distributing work. The industry trend is to use multiple transfer chamber robots to stack the quad-station modules in a series, particularly for etch products. In this work, the quad-station cluster tool wafer movement is modeled by using Petri net as a process-bounded system. The system analysis and simulations are performed by using timed and colored Petri nets. The results are useful to deepen our understanding of the discrete-event dynamics of quad-station module cluster tools and offer the highly needed insight into their efficient and deadlock-free operation.
