    摘要: A method of virtual metrology is disclosed. Process data and measurement values corresponding to a workpiece are collected. The process data and the measurement values are used to establish a conjecture model. A theoretical model corresponding to the workpiece and the conjecture model is used to establish another conjecture model. The another conjecture model is used to establish a virtual metrology value. The virtual metrology value is used to predict properties of a subsequently manufactured workpiece.
