    摘要: A critical dimension controlling method in a semiconductor production process includes determining whether a model is to undergo a discontinuous production process when a run is inserted in a semiconductor manufacturing line, applying an offset for said model or a common offset for a model group including said model according to the determination, executing a production process in dependence upon a process variation along with the offset for the model or the common offset for the model group, and measuring an actual critical dimension in the production process. The offset for the model is calculated based on a previously measured actual critical dimension, and the calculated offset for the model is applied to the calculation of the common offset for the model group.

    摘要: A method for adjusting a data set defining a set of process runs, each process run having a set of data corresponding to a set of variables for a wafer processing operation is provided. A model derived from a data set is received. A new data set corresponding to one process run is received. The new data set is projected to the model. An outlier data point produced as a result of the projecting is identified. A variable corresponding to the one outlier data point is identified, the identified variable exhibiting a high contribution. A value for the variable from the new data set is identified. Whether the value for the variable is unimportant is determined. A normalized matrix of data is created, using random data and the variable that was determined to be unimportant from each of the new data set and the data set. The data set is updated with the normalized matrix of data.

    摘要: A dual-phase virtual metrology method is disclosed for considering both promptness and accuracy by generating dual-phase virtual metrology (VM) values, wherein a Phase-I conjecture step emphasizes promptness by immediately calculating the Phase-I virtual metrology value (VMI) of a workpiece once the entire process data of the workpiece are completely collected; and a Phase-II conjecture step intensifies accuracy, which does not re-calculate the Phase-II virtual metrology values (VMII) of all the workpieces in the cassette until an actual metrology value (required for tuning or re-training purposes) of a selected workpiece in the same cassette is collected. Besides, the accompanying reliance index (RI) and global similarity index (GSI) of each VMI and VMII are also generated.

    摘要: A method and system for generating/regenerating a schedule of a set of events associated with at least one process in a manufacturing plant in real time. The schedule is generated/regenerated on the basis of the occurrence of one or more events associated with various processes in real time. The occurrence of each of the events is monitored continuously. Thereafter, the occurrence of the monitored events is predicted for one or more predefined instances of time. The schedule is optimized on the basis of the predicted occurrences of the monitored events to generate/regenerate the schedule. The optimized schedule may be used to control one or more automatons.
