제목 Nanoporous Templates with High Aspect Ratio Using Silicon-Containing Block Copolymers and Dual Responsive Photoresists
초록 A simple and scalable method was developed to fabricate a nanoporous template for freestanding one-dimensional nanostructure arrays based on self-assembly of silicon-containing block copolymers and a lithographic bilayer system. Removal of the cross-linked bottom layer after fabrication is not easy. Therefore, we propose a dual responsive bottom layer into which the nanopatterns of block copolymer are transferred by oxygen reactive ion etching. Because the dual responsive layer becomes cross-linked by heating, it can be used as a hard template during the etching process. It becomes soluble again by chain scission upon exposure to light. Therefore, it can be easily removed by the lift-off process. The results will be described in detail.
