    摘要: Provided is system and method for controlling a fabrication cluster using at least one parameter of a structure measured with an optical metrology system designed and configured to meet one or more signal criteria. The design of the optical metrology system is optimized by using collected signal data in comparison to set one or more signal criteria. In one embodiment, the optical metrology system is used for standalone systems. In another embodiment, the optical metrology system is integrated with a fabrication cluster in semiconductor manufacturing. At least one parameter determined from a signal measured using the optical metrology system is transmitted to a fabrication cluster. The at least one parameter is used to modify at least one process variable or equipment setting of the fabrication cluster.
