Abstract
A method for analyzing a polymer membrane, which can improve accuracy of structural analysis of the polymer membrane and shorten the analysis time by effectively removing noise is provided.
Claims5
A method for analyzing a polymer membrane comprising
- blurring an original image of a polymer membrane having a block copolymer which is formed in trenches disposed at regular intervals and self-assembled to produce a blurring-processed image;
- Fourier-transforming the original image and the blurring-processed image to produce a Fourier transformation result of the original image and a Fourier transformation result of the blurring-processed image;
- removing noise from the Fourier transformation result of the original image and the Fourier transformation of the blurring-processed image;
- wherein the removing noise includes removing an overlapping range of the Fourier transformation result of the original image and the Fourier transformation result of the blurring-processed image.
