Photo-Cleavable Cross-Linked Nanoporous Templates via Dual Responsive Photoresists and Silicon-Containing Block Copolymers |
| 초록 |
A simple and novel method was developed to fabricate a photo-cleavable cross-linked nanoporous template for freestanding one-dimensional (1D) 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. These versatile templates of nanoporous structures can be applied to create freestanding 1D nanostructures of a variety of functional materials. |
