The substrate is provided with features formed atop that constitute an existing topography, and a template for directed self-assembly (DSA) surrounds the exposed topography. Further to the method, the template is filled with a block copolymer (BCP) to cover the exposed topography, and then the BCP is annealed within the template to drive self-assembly in alignment with the topography. Developing the annealed BCP exposes a DSA pattern immediately overlying the topography."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Use of topography to direct assembly of block copolymers in grapho-epitaxial applications","description":"A method is provided for forming a patterned topography on a substrate.
