Abstract: The defect inspection method of pattern is provided to reduce the repeated pattern check according to the inspection setting sensitivity. The first test susceptibility for the defect check of pattern is set up(S30a). The first deformity detection parameter according to the first test susceptibility is set up(S31a). The same pattern is scanned and the error signal size of the same pattern is calculated(S34a). The first deformity detection parameter and the error signal size are compared(S35a) and then it is determined whether the pattern has a defect or no. The error signal size of the same pattern and image of the same pattern are stored if the pattern has a defect(S36a).
