Method and system for semiconductor process control and monitoring by using a data quality metric
摘要:
During fault detection of a production process, the influence of the data communication process for communicating measurement readings to the fault detection system may be taken into consideration. In one illustrative embodiment, a data rate related parameter may be used as an input variable for a data reduction procedure, thereby enabling an efficient assessment of the quality of the remaining “real” process and tool parameters.
