Abstract: For cluster tools with residency time constraints in semiconductor manufactory, online scheduling problem was studied when temporary wafers arrived with emergency order, rework and new product development, et al. Utilizing available resource interval, the two-layer online scheduling method was proposed without changing existing schedule. The outer layer algorithm used an improved quantum evolutionary algorithm to optimize processing order of temporary wafers. Based on the results, the inner layer algorithm gained feasible solutions from available space by backward stepwise recursive strategy, and determined start time of wafer in feasible solution space by means of reverted sequence maximum backtrack strategy. Simulation results and comparisons on benchmarks with different scales demonstrate the effectiveness of the presented method.
