Abstract:
1. A device comprising: a substrate, at least a part of the substrate coated with a film comprising a block copolymer which is at least partially annealed and at least a portion of the block copolymer is removed after annealing, a structural guide on the substrate, the structural guide being removably affixed to the substrate, a part of the structural guide being coated with a hydrophobic polymer, wherein the hydrophobic polymer interacts with the hydrophobic block such that the hydrophobic block is aligned according to a shape of the hydrophobic polymer on the part of the structural guide, so that the hydrophobic block is oriented in a same direction relative to the shape of the hydrophobic polymer, wherein the structural guide comprises one of a nano frame formed in the structural guide or a protruded nano beam formed on the structural guide.
