Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The method for analyzing a polymer membrane according to claim 1 , further comprising: measuring a pitch of a pattern formed on a surface of the polymer membrane from the Fourier-transformed result of the noise-removed original image. 3. The method for analyzing a polymer membrane according to claim 2 , wherein the measuring the pitch includes measuring a peak formed by radially integrating the Fourier-transformed result of the noise-removed original image of the polymer membrane in the range of 0° to 360°. 4. The method for analyzing a polymer membrane according to claim 1 , wherein the self-assembled structure of the block copolymer is a cylinder, sphere or lamellar structure. 5. The method for analyzing a polymer membrane according to claim 1 , wherein the original image of the polymer membrane is an image obtained through a scanning electron microscope (SEM), an atomic force microscope (AFM) or a transmission electron microscope (TEM).
