    摘要: An average fault ratio is calculated from product characteristics of a product as a target of yield prediction, in order to predict yield accurately in the course of manufacturing the prediction target product.With respect to a reference product, whose wiring pattern is different from the prediction target product but manufactured by the same manufacturing process, a monthly electric fault density is calculated from actually measured data. Respective average fault ratios are obtained from product characteristics of the prediction target product and the reference product. A monthly electric fault density of the prediction target product is obtained by multiplying the monthly electric fault density of the reference product by the ratio of the average fault ratios. The yield is calculated by using the monthly electric fault density of the month in which a yield prediction target lot of the prediction target product was processed.

    摘要: A plasma processing control system and method which can suppress influences caused by disturbances. The control system includes a plasma processor for performing processing operation over a sample accommodated within a vacuum processing chamber, a sensor for monitoring process parameters during processing operation of the plasma processor, a processed-result estimation model for estimating a processed result on the basis of a monitored output of the sensor and a preset processed-result prediction equation, and an optimum recipe calculation model for calculating correction values of processing conditions on the basis of an estimated result of the processed-result estimation model in such a manner that the processed result becomes a target value. The plasma processor is controlled on the basis of a recipe generated by the optimum recipe calculation model.
