Publication number: 20240176335Abstract: 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.

Patent number: 11821847Abstract: 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.Type: GrantFiled: July 20, 2021Date of Patent: November 21, 2023Assignee: UNITED MICROELECTRONICS CORP.Inventors: Cheng-Hsien Chen, Chia-Feng Hsiao, Chung-Hsuan Wu, Chen-Hui Huang, Nai-Ying Lo, En-Wei Tsui, Yung-Yu Yang, Chen-Hsuan Hung
