Graphoepitaxial Assembly of Symmetric Block Copolymers on Weakly Preferential Substrates

Abstract

Weakly preferential substrates were utilized in a single step process to direct the assembly of symmetric PS-b-PMMA. The thickness dependence of domain orientation on weakly preferential substrates was exploited to dictate the lateral ordering of perpendicular lamellae.
