Using an array of majority‐block‐functionalized posts makes it possible to locally control the self‐assembly of a block copolymer and achieve several morphologies on a single substrate. A template consisting of a square symmetry array of posts produces a square‐symmetry lattice of microdomains, which doubles the areal density of features.
