Multiscale Nanopatterns Templated from Two‐Dimensional Assemblies of Photoresist Particles

Multiscale nanopatterns fabricated by colloidal lithography, using two-dimensional self-assemblies of photoresist particles as masks, are presented. The colloidal masks with features of multiple length scales are obtained by photolithography and used for constructing submicrometer-hole arrays over large areas (see Figure). By depositing functional materials through these masks, nanopatterned substrates useful in a wide range of applications can be produced.
