Abstract :
The main objective of this study is to develop systems for 28 nano-meter back end lithography productivity cycle time improvement. The paper surveys applications of Queueing theory, Fuzzy theory and OR for system development. We develop four systems such as Loading forecast system, Photo all in one, OD (Oxide Definition) intelligent scheduling system, Self accelerating system and Scanner dashboard which can linearize tool utilization, predict coming WIP (Work In Process) in future, coming WIP variation minimization and monitor tool unit status respectively. Finally, the lithography productivity cycle time reduction can be achieved 40%.
