Embodiment
[0047] This embodiment provides a method for automatically classifying failure information of a CIS image sensor, such as figure 2 As shown, the automatic classification method includes:
[0048] The CIS image sensor outputs a picture file of the detection result. Further, the detection result picture file is a BMP (abbreviation for bitMap) picture file, and may also be other types of picture files. BMP is an integration of pixels with a certain width and height, including 2-color bitmap, 16-color bitmap, 256-color bitmap and 24-bit bitmap. Semiconductor testing equipment generally outputs a black and white image of a 256-color bitmap. Observe with the naked eye, it can be found that where there is a failure bit, it will display a darker color with different gray levels, and other places will display a whiter color with different gray levels. , see figure 1 shown.
[0049] Interpret the test result picture file and extract failure information. The specific process include...
