| Outline of Final Research Achievements |
For developing advanced molecular placement technology and establishing a research foundation of sub-nano interface thin film materials utilizing the perpendicularly oriented interface of block copolymers, new block copolymers in which a variety of functional groups can be introduced were successfully developed.
In particular, by introducing functional groups with excellent surface segregation properties, thinning of nanodomains, perpendicular orientation control, and long-range structural ordering in thin films were established. Detailed structural analysis of the surface and cross-section of the thin films revealed the process of the perpendicular orientation of the microphase-separated nanostructures from an experimental point of view. Based on the results of these fundamental studies, a path to the establishment of elemental technologies for the development of next-generation lithography materials and sub-nano interface thin film materials were successfully achieved.
