  • Publication number: 20240176335
    Abstract: A fault detection method, includes the following steps. A target sequence is received, the target sequence includes several data. A first moving average operation is performed on the target sequence to establish a first moving average sequence. A second moving average operation is performed on the target sequence to establish a second moving average sequence. A difference operation between the first moving average sequence and the second moving average sequence is performed to obtain a difference sequence, the difference sequence includes several difference values. An upper limit value is set. When one of the difference values is greater than the upper limit value, the target sequence is determines as abnormal.

    Abstract: A fault detection method comprises the following steps. Receiving a first original sequence comprising a plurality of first data. Receiving a second original sequence comprising a plurality of second data. Aligning the first original sequence with the second original sequence according to trends of value changing of the first data and the second data. Performing an average operation on the aligned first original sequence and second original sequence to establish a standard sequence. Performing a difference operation between the first original sequence and the standard sequence to obtain a first total difference value. Performing a difference operation between the second original sequence and the standard sequence to obtain a second total difference value.

  • Patent number: 11821847
    Abstract: A wafer backside defect detection method and a wafer backside defect detection apparatus are provided. The wafer backside defect detection method includes the following steps. A peripheral edge area of a wafer backside image that at least one notch is located is cropped off. Adjacent white pixels on the wafer backside image are connected to obtain a plurality of abnormal regions. If a total area of top N of the abnormal regions is more than 10% of an area of the wafer, it is deemed that the wafer has a roughness defect. N is a natural number. If the total area of the top N of the abnormal regions is less than 1% of the area of the wafer and a largest abnormal region of the abnormal regions is longer than a predetermined length, it is deemed that the wafer has a scratch defect.

  • Patent number: 11644427
    Abstract: An automatic detection method and an automatic detection system for detecting any crack on wafer edges are provided. The automatic detection method includes the following steps. Several wafer images of several wafers are obtained. The wafer images are integrated to create a templet image. Each of the wafer images is compared with the templet image to obtain a differential image. Each of the differential images is binarized. Each of the differential images which are binarized is de-noised. Whether each of the differential images has an edge crack is detected according to pattern of each of the differential images which are de-noised.
