Topographical confinement is used to template the formation of nanoscale domains in a self-assembled block copolymer film. The topographical template controls the row spacings and feature dimensions of the copolymer and can deliberately introduce defects in the arrays (see Figure). For example, a sharp edge feature leads to a missing domain and pins the lateral position of the polymer array. (See also inside cover.)
