Individual Confinement of Block Copolymer Microdomains in Nanoscale Crossbar Templates

Highly ordered pattern formation of block copolymers (BCPs) within nanoscale templates is of great interest for generating diverse ordered nanostructures. Here, introduced is a combined methodology of nanotransfer printing (nTP) and BCP self‐assembly to guide the formation of spherical nanodots with...

Zusammenfassung:Highly ordered pattern formation of block copolymers (BCPs) within nanoscale templates is of great interest for generating diverse ordered nanostructures. Here, introduced is a combined methodology of nanotransfer printing (nTP) and BCP self‐assembly to guide the formation of spherical nanodots within a printed crossbar nanotemplate. By successfully accommodating poly(styrene‐b‐dimethylsiloxane) (PS‐b‐PDMS) BCPs in the guiding metallic crossbar nanotemplate (≈30 × 30 nm2), a well‐organized array of single‐domain PDMS spheres (≈10 nm) with a square symmetry is successfully obtained in an extremely short annealing time (
