Abstract:
1. A pattern correction method in which a shape of a target pattern is corrected in accordance with an arrangement state between the target pattern configuring a designed pattern and a vicinity pattern disposed in the vicinity of the target pattern, the pattern correction method comprising: detecting a first arrangement state between a first predetermined portion of an edge of the target pattern and the vicinity pattern; detecting a second arrangement state between a second predetermined portion of the edge of the target pattern and the vicinity pattern; determining a correction value of the edge of the target pattern based on a rule in accordance with the first and second arrangement states; and adding the correction value to the edge of the target pattern, wherein: the first and second arrangement states are indicated by a distance between the edge of the target pattern and the edge of the vicinity pattern existing in a direction crossing the edge of the target pattern at right angles; and determining the correction value is performed by determining a first correction value in a case where the first arrangement state is equal to the second arrangement state, and determining a second correction value in a case where the second arrangement state is larger than the first arrangement state, and the second correction value is smaller than the first correction value.
