Generation of combinatorial patterns by deliberate tilting of a polymer-pen array

Abstract

The disclosure relates to a method of forming a pattern having pattern elements with a plurality of sizes on a substrate surface with a tilted pen array that includes choosing a tilt geometry for a pen array with respect to a substrate, inducing the tilt geometry between the pen array and the substrate surface, and forming a pattern having pattern elements on the substrate surface with the titled pen array, whereby the size of the formed pattern elements varies across the substrate surface along the tilted axis or axes. For example, the tilt geometry is in reference to the substrate surface and comprises a first angle with respect to a first axis of the substrate and a second angle with respect to a second axis of the substrate, the second axis being perpendicular to the first axis, and at least one of the first and second angles being non-zero.
