    Abstract: A method of fault detection and classification in semiconductor manufacturing is provided. In the method, delicate variations of actual data of parameters for which normal values of a manufacturing condition change according to time are detected very precisely and sensitively, and accordingly major variation components for a step which has a high occurrence occupancy are acquired to achieve a very precise and effective fault detection and classification (FDC). In the method, continuous steps in a process are regarded as separate processes which are not related to each other and covariance and covariance inverse matrixes acquired for each step are set as references to decrease values of variance or covariance compared with those for a case where references are calculated based on total steps. Accordingly, Hotelling's T-square values for a small variation are increased, so that a delicate variation can be sensitively detected.
