Three‐dimensional Directed Assembly of Block Copolymers together with Two‐dimensional Square and Rectangular Nanolithography

Self-assembling sphere-forming block copolymers that normally adopt a hexagonal packing in thin films were directed to assemble on chemically patterned surfaces into their three-dimensional bulk-like body-centered cubic morphology; two-dimensional manufacturing-relevant patterns with square and rectangular symmetry could be derived from the films using molecular transfer printing at a resolution beyond the limits of current lithographic tools and materials.
