碩士 === 國立交通大學 === 工業工程與管理系 === 89 === Due to the complexity of semiconductor manufacturing and the unexpected occurrence of undesirable events in the fabrication, it is not easy to manage the production cycle time. Usually, the management method is by releasing and dispatching. These methods need much time to analyze data, and usually can not effectively manage the fabrication in time. The purpose of this research is to construct a management mechanism for cycle time reduction. The method is by real time monitoring the difference between target cycle time and actual cycle time. According to the “time difference”, the monitor system will detect every possible delayed lots and order to correct the undesirable events. Then, the real time monitor system will send alarm information to the people who is responsible for the corrective action. According to the simulation result, this monitor system can provide the manager real time information to manage the fabrication well.
