Manipulation of block copolymer microdomains by a top metal layer |
| 초록 |
So far, self-assembled block copolymer (BCP) microdomains have been guided or manipulated by the controls of bottom surfaces and/or side walls of lithographically defined templates. If BCP microdomains can be influenced by controlling the top surface of BCP films, we can obtain one more key to handle a BCP self-assembly process. We found PDMS disks are significantly deformed if depositing metal layers on top of a PS-PDMS block copolymer thin film before self-assembly. Metal layers provide strong constrain on underlying BCP films since their chians should be frustrated to fit into the flat interface between the metal and BCP films. The deformation mechanism will be discussed based on series of experimental results and theoretical models. We also suggest a homopolymer mixing technique to relieve the deformation of polymer chains and to induce the formation of more spherical PDMS microdomains. |
