Title:
PREPARATION METHOD OF PATTERNED SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2019/054768
Kind Code:
A1
Abstract:
The present application relates to a method for preparing a patterned substrate. According to the method of the present application, in a process of transferring a self-assembled pattern of a block copolymer on a substrate to form a pattern, the self-assembled pattern of the block copolymer can be efficiently and accurately transferred on the substrate to prepare a patterned substrate.
