Abstract
Methods of forming an array of patterns on a substrate are provided. An array of protective tiles formed from a protectant resin is provided to cover an array of sub-regions on the substrate. An array of patterns is formed on the substrate by sequentially repeating steps (i) and (ii) for each sub-region: (i) removing the protective tile from one of the sub-regions to expose the first major surface underneath; and (ii) forming a pattern on the exposed first major surface within the one of the sub-regions.
