Claim:
A pattern verifying method, which divides a full pattern into a first pattern and a second pattern, which is used for a double patterning method for forming the second pattern in a film to be processed after forming the first pattern in the film to be processed, for verifying the first pattern and the second pattern, said pattern verifying method comprising: simulating a double patterning exposure process of the first pattern and the second pattern to generate a first simulated pattern and a second simulated pattern; correcting, by using a computer, at least one of the first pattern and the second pattern based on an overlapping margin between the first simulated pattern and the second simulated pattern, which includes an allowable alignment mismatch amount when the second pattern is aligned to the first pattern; calculating a relative distance between the first simulated pattern and the second simulated pattern after the overlapping margin is corrected; and determining whether the relative distance is wider than a criterion value by: determining whether the first simulated pattern and the second simulated pattern are separated from each other by the criterion value or more in a part in which the first pattern and the second pattern are to be separated from each other; determining whether the first simulated pattern and the second simulated pattern are overlapped with each other by the criterion value or more in a part in which the first pattern and the second pattern are to be overlapped with each other; correcting at least one of the first pattern and the second pattern so that the first simulated pattern and the second simulated pattern are separated from each other by the criterion value or more in the part in which the first pattern and the second pattern are to be separated from each other when the relative distance does not satisfy the criterion; and correcting at least one of the first pattern and the second pattern so that the first simulated pattern and the second simulated pattern are overlapped with each other by the criterion value or more in a part in which the first pattern and the second pattern are to be overlapped with each other when the relative distance does not satisfy the criterion.
