Patent number: 10153173Abstract: The present invention relates to a process for selectively removing a block on one side using a wet etching process in connection with self-assembly block copolymer thin films that have etching-resisting properties different from each other. The present invention can form a vertical nanopore structure having a high aspect ratio, even in the case of a thick film which has a vertically oriented cylinder self-assembly structure and which has one or more periods, by overcoming the limit of the prior art, which cannot implement a vertical pore structure through wet etching.Type: GrantFiled: February 2, 2016Date of Patent: December 11, 2018Assignee: LG Chem, Ltd.Inventors: Se Jin Ku, Eun Young Choi, Sung Soo Yoon, No Jin Park, Jung Keun Kim, Je Gwon Lee, Mi Sook Lee
