A method for automatically controlling defect-specification in a semiconductor manufacturing process is provided. The method provides a module to detect a position, number, size, and intensity signals of defects on a processed patterned wafer. The module further compares the patterned wafer with a normal wafer to preliminarily classify the patterned wafer and creates a defect map. Then, a defect management system is provided to execute a spatial pattern recognition procedure to determine whether or not the corresponding special pattern can be recognized. Finally, messages will be automatically sent by the defect management system to inform related e-mail accounts according to results of the recognition of the special pattern.
A method for automatically controlling defect-specification in a semiconductor manufacturing process, the method comprising:
The method of claim 2, wherein if the sample wafer cannot pass the detection according to the defect map, the defect management system executes the following steps after step (D):
The method of claim 2, wherein the module is utilized to perform a bright field (BF) defect detection in step (B) to detect a position, number, size, and intensity signal of physical defects on the sample wafer.
