Modeling the Effect of Hot Lots in Semiconductor Manufacturing Systems

  title={Modeling the Effect of Hot Lots in Semiconductor Manufacturing Systems},
  author={Y. Narahari and L. M. Khan},
The presence of hot lots or high-priority jobs in semiconductor manufacturing systems is known to significantly affect the cycle time and throughput of the regular lots since the hot lots get priority at all stages of processing. In this paper, we present an efficient analytical model based on re-entrant lines and use an efficient, approximate analysis methodology for this model in order to predict the performance of a semiconductor manufacturing line in the presence of hot lots. The proposed… CONTINUE READING
