Regular arrays of microstructures arise from capillary interactions when a patterned elastomeric mold is placed on top of a line-and-space patterned polymer at an angle and the polymer is heated above its glass transition temperature. The Figure shows a self-organized microstructure obtained from 90°-shifted molds with line-and-space patterns by annealing at 130 °C for 60 min.
