According to one embodiment, a method for generating mask data is configured to form a circuit pattern on a substrate using a directed self-assembly material. The method includes extracting a first region, setting a second region and setting a third region. The first region does not existing in the circuit pattern and existing in an initial pattern. The initial pattern includes a plurality of interconnect patterns extending in a first direction. The second region is formed by elongating the first region in a second direction intersecting the first direction. The second region straddles the first region in the second direction. The third region includes at least one of the second regions. The directed self-assembly material is disposed in the third region. |
