Abstract

According to one embodiment, a guide pattern data correcting method is for correcting guide pattern data of a physical guide for formation of a polymer material to be microphase-separated. The physical guide has a plurality of concave portions in the guide pattern data, and at least two concave portions out of the plurality of concave portions are connected to each other. The guide pattern data is subjected to correction by shifting or rotation of at least either of the two connected concave portions.

Claims (20)

1. A guide pattern data generating method for correcting guide pattern data of a physical guide for formation of a block copolymer material to be microphase-separated,

wherein:

the physical guide has a plurality of portions in the guide pattern data, the plurality of portions being disposed along a predetermined direction within a plane based on the pattern data of the plurality of portions, the pattern data of the plurality of portions being included in the guide pattern data, and

at least two portions out of the plurality of portions are connected to each other,

the method comprising:

subjecting the guide pattern data to correction in such a manner that the portions that have ends respectively connected to other portions rotate about the portion's centroid within the plane wherein:

the correction causes the size of a region shared by the at least two connected portions to reduce.

2. The guide pattern data generating method according to claim 1 , wherein rotating the portions includes rotating 4 degrees.

3. The guide pattern data correcting method according to claim 1 , wherein centroids of the plurality of portions are disposed on a straight line.

4. The guide pattern data correcting method according to claim 1 , wherein one portion of the two portions connects to an end portion which does not rotate.

5. A guide pattern data generating method for correcting guide pattern data of a physical guide for formation of a block copolymer material to be microphase-separated,

wherein:

the physical guide has a plurality of portions in the guide pattern data, the plurality of portions being disposed along a predetermined direction within a plane based on the pattern data of the plurality of portions, the pattern data of the plurality of portions being included in the guide pattern data, and

at least two portions out of the plurality of portions are connected to each other,

the method comprising:

subjecting the guide pattern data to correction in such a manner that a portion which has an end connected to another portion of the two portions rotate about the portion's centroid within the plane, the portion being one portion of the two portions, wherein:

the correction causes the size of a region shared by the at least two connected portions to reduce.

6. The guide pattern data generating method according to claim 5 , wherein rotating the portions includes rotating 4 degrees.

7. The guide pattern data correcting method according to claim 5 , wherein centroids of the plurality of portions are disposed on a straight line.

8. The guide pattern data correcting method according to claim 5 , wherein the one portion is an end portion.
