Abstract: Embodiments of the disclosure disclose a method and structure for detecting distortion in a pattern. In this solution, a first photosensitive material is exposed and developed to form a desirable pattern to be detected, and also a detection step including two levels at different heights is formed in a preset detection area of the pattern to be detected; and then a second photosensitive material is exposed and developed according to the same exposure machine parameters to form a detection pattern in the detection area for detecting exposure defocusing, and if preset size parameters of the detection pattern at the two levels of the detection step are consistent, then it is indicated that the formed pattern to be detected is not distorted due to exposure defocusing; otherwise, it is indicated that the pattern to be detected is distorted due to exposure defocusing.
