Abstract
A method for determining a self-assembly pattern of a block copolymer confined inside a closed outline called the guiding outline, comprises the following steps, which are implemented by computer: a) choosing in a database a closed outline called the reference outline that is similar to the guiding outline, a self-assembly pattern of the block copolymer, called the reference pattern, being associated with the reference outline; b) applying a geometric transformation to a plurality of points of said reference pattern in order to convert them to respective points called image points of the self-assembly pattern to be determined. A computer program product for implementing such a method is provided.

A method for determining a self-assembly pattern of a block copolymer confined inside a closed outline called a guiding outline, including the following steps, which are implemented by computer:
- a) forming a database by acquiring and/or storing in a memory of the computer a plurality of discretized images corresponding to different guiding outlines of the self-assembly pattern of a given block copolymer;
- and choosing with the computer from the database a closed outline called a reference outline that is similar to said guiding outline, a self-assembly pattern of said block copolymer, which is called a reference pattern, being associated with said reference outline;
- and
- b) applying with the computer a geometric transformation to a plurality of points of said reference pattern in order to convert the plurality of points to respective points called image points of the self-assembly pattern to be determined, said geometric transformation being a function of a geometric transformation allowing said reference outline to be converted to said guiding outline.
A non-transitory computer program product comprising programming code instructions for executing steps of a method for determining a self-assembly pattern of a block copolymer confined inside a closed outline called a guiding outline when said non-transitory computer program is executed on a computer, the method including the following steps:
- a) forming a database by acquiring and/or storing in a memory of the computer a plurality of discretized images corresponding to different guiding outlines of the self-assembly pattern of a given block copolymer;
- and choosing with the computer from the database a closed outline called a reference outline that is similar to said guiding outline, a self-assembly pattern of said block copolymer, which is called the reference pattern, being associated with said reference outline;
- and
- b) applying with the computer a geometric transformation to a plurality of points of said reference pattern in order to convert the plurality of points to respective points called image points of the self-assembly pattern to be determined, said geometric transformation being a function of a geometric transformation allowing said reference outline to be converted to said guiding outline.
