Hierarchical self‐assembly of block copolymers has been achieved by two steps of sequential ordering processes, consisting of self‐organized micropatterning from a dewetting block polymer solution and thermal annealing. The self‐organized micropattern induces the spontaneous alignment of self‐assembled lamellae (see figure), which is successfully applied for a lithography‐free, ultra‐large‐scale nanopatterning.
